A message came shortly with the Queen's commands that I should repair to the palace on the following afternoon to be presented to her Majesty. It was near morning when I got back to the hotel. 8th.

The Secretary of State, Ka (the Earl of Clarendon), invited me to an interview with him in the afternoon, when, in addition to other conversation, he stated that the Queen had spoken approvingly of me, and also that, being aware I was about to visit other countries, he had been good enough to send communications notifying the fact, in order that wherever I went I might find hospitable entertainers. This is kindness and attention for which one should certainly feel grateful. Went next to the Earl of T.'s, where a large party of distinguished guests were invited, and where the lady of the house treated me with the utmost hospitality. After a time we repaired to the garden, and looked on while the lady visitors played at ball (croquet), during which time music was discoursed by a band. The assemblage of elegant toilettes was truly a sight to behold! 20th. Rain. The Duke of P. invited us to a public assembly to witness a ball. The number of guests of both sexes was considerable (lit. exceeded several tens). All the officials present wore their court uniforms, the same as at the palace entertainment. It was 2 A.M. when I got back to the hotel. The majority of the guests, it was stated, were Scottish, and of the ladies two or three in every ten had white hair, though their faces were youthful and blooming. In answer to my inquiries I was told that the hair was artificially whitened. One not conversant with the fact might almost have taken youthful matrons for grand mothers! 22nd. Mr. B. of the Crystal Palace invited us to see the fountains. The landscape scenery and grottoes which they went through with us were very pretty sights. Returned home after a dinner in the evening. It was close upon midnight when we got back. On this day we saw a native of the province of Hu-peh, not more than three feet high, and also a man from Ngan-hevei, eight or nine feet in height- both remarkable specimens of humanity. A foreigner has brought them for a tour in this country. 23rd. Fine. At 9 A.M. embarked on board a steamer and left port for Holland. From Chambers' Journal. OZONE. RECENTLY, the singular gas termed ozone has attracted a large amount of attention from chemists and meteorologists. The vague ideas which were formed as to its nature when as yet it had been but newly discovered, have given place gradually to more definite views; and though we cannot be said to have thoroughly mastered all the difficulties which the strange element presents, yet we know already much that is interesting and instructive. Let us briefly consider the history of ozone. Nine years after Priestley had discovered oxygen, Van Marum, the electrician, noticed that when electric sparks are taken through that gas, a peculiar odour is evolved. Most people know this odour, since it is always to be recognized in the neighbourhood of an electrical machine in action. In reality, it indicates the presence of ozone in the air. But for more than half a century after Van Marum had noticed it, it was supposed to be the " smell of electricity." In 1840, Schönbein began to inquire into the cause of this peculiar odour. He presently found that it is due to some change in the oxygen; and that it can be produced in many ways. Of these, the simplest, and, in some respects, the most interesting, is the following: "Take sticks of common phosphorus, scrape them until they have a metallic lustre, place them in this condition under a large bell-jar and half-cover them with water. The air in the bell-jar is soon charged with ozone, and a large room can readily be supplied with ozonized air by this process.' Schönbein set himself to inquire into the properties of this new gas, and very interesting results rewarded his researches. It became quite clear, to begin with, that whatever ozone may be, its properties are perfectly distinct from those of oxygen. Its power of oxidizing or rusting metals, for example, is much greater than that which oxygen possesses. Many metals which oxygen will not oxidize at all, even when they are at a high temperature, submit at once to the influence of ozone. But the power of ozone on other substances than metals is equally remarkable. Dr. Richardson states that, when air is so ozonized as to be only respirable for a short time, its destructive power is such that gutta-percha and india-rubber tubings are destroyed by merely conveying it. The bleaching and disinfecting powers of ozone are very striking. Schönbein was at first led to associate them with the qualities | the combination of two special forms of of chlorine gas; but he soon found that oxygen- the positive and the negative; they are perfectly distinct. It had not yet been shewn whether ozone was a simple or a compound gas. If simple, of course it could be but another form of oxygen. At first, however, the chances seemed against this view; and there were not wanting skilful chemists who asserted that ozone was a compound of the oxygen of the air with the hydrogen which forms an element of the aqueous vapour nearly always present in the atmosphere. It was important to set this question at rest. This was accomplished by the labours of De la Rive and Marignac, who proved that ozone is simply another form of oxygen. Here we touch on a difficult branch of modern chemical research. The chemical elements being recognized as the simplest forms of matter, it might be supposed that each element would be unchangeable in its nature. That a compound should admit of change, is of course à thing to be expected. If we decompose water, for instance, into its component elements, oxygen and hydrogen, we may look on these gases as exhibiting water to us in another form. And a hundred instances of the sort might be adduced, in which, either by separating the elements of a compound, or by rearranging them, we obtain new forms of matter without any real change of substance. But with an element, the case, one would suppose, should be different. However, the physicist must take facts as he finds them; and amongst the most thoroughly recognized chemical facts we have this one, that elementary substances may assume different forms. Chemists call the phenomenon allotropy. A well-known instance of allotropy is seen in red phosphorus. Phosphorus is one of the chemical elements; and, as every one knows, the form in which it is usually obtained is that of a soft, yellow semi-transparent solid, somewhat resembling bees'-wax in consistence, poisonous, and readily taking fire. Red phosphorus is the same element, yet differs wholly in its properties. It is a powder, it does not readily take fire, and it is not poisonous. Ozone, then, is another form of oxygen. It is the only instance yet discovered of gaseous allotropy. or, as he called them, ozone and antozone. He shewed that, in certain conditions of the air, the atmospheric oxygen exhibits qualities which are the direct reverse of those which ozone exhibits, and are distinct from those of ordinary oxygen. In oxygen thus negatived, or antozonised, animals cannot live any more than they can in nitrogen. The products of decomposition are not only not destroyed as by ozone, but seem subject to preservative influences, and speedily become singularly offensive; dead animal matter rapidly putrefies, and wounds shew a tendency to mortification. But the theory of positive and negative forms of oxygen, though still held by a few physicists, has gradually given way before the advance of new and sounder modes of inquiry. It has been proved, in the first place, that ozone is denser than ordinary oxygen. The production of ozone is always followed by a contraction of the gas's volume, the contraction being greater or less according to the amount of oxygen which has been ozonized. Regularly as the observers - Messrs Andrews and Tait — converted a definite proportion of oxygen into ozone, the corresponding contraction followed, and as regularly was the original volume of the gas restored when, by the action of heat, the ozone was reconverted into oxygen. And now a very singular experiment was made by the observers, with results which proved utterly perplexing to them. Mercury has the power of absorbing ozone; and the experimenters thought that if, after producing a definite contraction by the formation of ozone, they could absorb the ozone by means of mercury, the quantity of oxygen which remained would serve to shew them how much ozone had been formed, and thence, of course, they could determine the density of ozone. Suppose, for instance, that we have one hundred cubic inches of oxygen, and that by any process we reduce it to a combination of oxygen and ozone occupying ninetyfive cubic inches. Now, if the mercury absorbed the ozone, and we found, say, that there only remained eighty-five cubic inches of oxygen, we could reason in this way: Ten cubic inches were occupied by And now we have to deal with the diffi- the ozone before the mercury absorbed it; cult and still-vexed questions of the way in but these correspond to fifteen cubic inches which the change from oxygen is brought of oxygen: hence, ozone must be denser than about, and the actual distinction between oxygen in the proportion of fifteen to ten, the two forms of the same gas. Schönbein or three to two. And whatever result holds that common oxygen is produced by might have followed, a real absorption of the ozone by the mercury would have as satisfactorily solved the problem. But the result actually obtained did not admit of interpretation in this way. The apparent absorption of the ozone by the mercury, that is, the disappearance of the ozone from the mixture, was accompanied by no diminution of volume at all. In other words, returning to our illustrative case, after the absorption of the ozone from the ninety-five cubic inches occupied by the mixture, there still remained ninety-five cubic inches of oxygen; so that it seemed as though 0 cubic inches of ozone corresponded in weight to five cubic inches of oxygen. This solution, of course, could not be admitted, since it made the density of ozone infinite. The explanation of this perplexing experiment is full of interest and instruction. We follow the account recently given by Mr. C. W. Heaton (Professor of Chemistry at Charing Cross Hospital) in the pages of a scientific contemporary, slightly modifying it, however, so that it may better suit our columns. cubic inches of oxygen gave up their atoms, each atom combining with one of the remaining oxygen doublets, so as to form a set of ozone triplets. Clearly, then, fifteen cubic inches of oxygen were transformed into ozone. They now occupied but ten cubic inches; so that the mixture, or ozonized oxygen, contained eighty five cubic inches of oxygen and ten of ozone. When the mercury was introduced, it simply transformed all the ozone triplets into oxygen doublets, by taking away the odd atom from each. It thus left ten cubic inches of oxywhich, with the remaining eighty-five, constituted the ninety-five cubic inches observed to remain after the supposed absorption of the ozone. It follows, of course, that ozone is half as heavy again as oxygen. But, as Mr. Heaton remarked, "this beautiful hypothesis, although accounting perfectly for all known facts, was yet but a probability. One link was lacking in the chain of evidence, and that link M. Soret has supplied by a happily devised experiment. Although mercury and most substances are only capable of converting ozone into oxygen, oil of turpentine has the power of absorbing ozone in its entirety. Thus, when the experiment was repeated, with oil of turpentine in the place of the mercury, the ozone was absorbed, and the remaining oxygen, instead of occupying ninety-five inches, occupied but eighty-five. After this, no doubt could remain that Dr. Odling's ingeniously conceived hypothesis was the correct explanation of Messrs. Andrews and Tait's experiment. Modern chemists adopt, as a convenient mode of representing the phenomena which gases exhibit, the theory that every gas, whether elementary or compound, consists of minute molecules. They suppose that these molecules are of equal size, and are separated by equal intervals so long as the gas remains unchanged in heat and density. The view serves to account for the features of resemblance presented by all gases. The features in which gases vary are accounted for by the theory that the molecules are differently constituted. The molecules are We recognize, then, in ozone a sort of supposed to be clusters of atoms, and the concentrated oxygen, with this peculiar qualities of a gas are assumed to depend on property, that it possesses an extraordinary the nature and arrangement of these ulti-readiness to part with its characteristic third mate atoms. The molecules of some elements atom, and so disappear as ozone, two-thirds consist but of a single atom; the molecules of its weight remaining as oxygen. of others are formed by pairs of atoms; those of others by triplets; and so on. Again, the molecules of compound gases consist of combinations of different kinds of atoms. It is to this peculiarity that ozone owes the properties which render it so important to our welfare. We are indeed, as yet, in no position to theorize respecting this element, our knowledge of its very existence being so recent, and our information respecting its presence in our atmosphere being of still more recent acquisition. Now, Dr. Odling, to whom we owe the solution of the perplexing problem described above, thus interpreted the observed phenomena. A molecule of oxygen contains two atoms, one of ozone contains three, and Indeed, it is well remarked by Mr. Heathe oxydizing power of ozone depends on the ton, that we had, until quite lately, no reaease with which it parts with its third atom son for confidently adopting Schönbein's of oxygen.
