Page 99 - ... example, very little increase of lung capacity can be expected ; yet even here, I have noted a decided improvement in the contour of the chest, as well as the acquirement of increased respiratory power. It is during childhood, however, that the greatest successes of physical culture are to be noted, and it is not difficult to understand why this should be the case. All the conditions are at that time favorable for development. The bones and cartilages forming the framework of the chest contain...
Page 39 - A personal and apparently immaterial event produced a revolution of public feeling, for which it would be difficult to find a parallel in the history of English politics.
Page 64 - Practically, therefore," adds Sir L. Bell, " the combustion of a unit of carbon burnt to carbonic oxide in a blast furnace of 80 feet gives nearly as good an effective result, although it evolves only 2,400 calories, as the same quantity of carbon burnt to carbonic acid in a low fire, although, in the latter case, 8,000 calories per unit of carbon are generated. There is, however, this marked difference between the two examples, that whereas the 7,992 heat units referred to in the case of the blast...
Page 65 - ... is indeed visible in the flame and incandescence at the surface of the fuel. On the other hand, in a blast furnace of 80 feet the materials are, it is true, red hot for more than 50 feet above the hearth, but the upper surface of the materials, instead of being red hot, exhibits little or no signs of incandescence, proving a comparative freedom from waste due to this cause.
Page 315 - Fuller's earth to the extent of 5 per cent of the weight of the tallow is added and the whole mass agitated about thirty minutes.
Page 470 - Law from the standpoint of the Law. In neither case are we able to call in question the propriety, or indeed the historical necessity, of such a line of procedure ; at the same time we cannot shut our eyes to the great difficulties which arise for thoughtful minds from this employment of conceptions belonging peculiarly to the antiquated standpoint in establishing and formulating the truth of the new principle. The contradictions and theoretical stumbling-blocks which are the inevitable consequences...

Page 370 - I think it has no equal ; as a melter 'it is inferior to many ; as to endurance it was the shortest-lived of any, and as to convenience of repairs it was one of the most difficult.
Page 228 - ... not only the virulence with which the febrile poison acts on the blood, but also the particular organic lesions which occur. Now these variable lesions which occur in various epidemics, and which are known to modify the duration of fevers, not being sufficiently characterized by symptoms during life, it is impossible to speak with any degree of confidence as to the precise organic lesion in them ; so that no numerical calculation will afford much aid to the practical physician in single cases....
