Page 102 - Some of our countrymen, engaged of late in conducting the principal mining association in Mexico *, carried out with them some English greyhounds of the best breed, to hunt the hares which abound in that country. The great platform which is the scene of sport is at an elevation of about...
Page 201 - French races, which are individually lost in the preponderance of English blood, and disappear almost entirely, leaving the improving type in the ascendant. The influence, in fact, of this type was so decided and so predominant, that all the lambs produced strikingly resembled each other, and even Englishmen took them for animals of their own country. But what was still more decisive, when these young ewes and rams were put together they produced lambs closely resembling themselves, without any marked...
Page 138 - Mr. Meynel's fox-hounds are likewise quoted as an instan.ce of the success of this practice; but upon speaking to that gentleman upon the subject, I found that he did not attach the meaning that I do, to the term in-and-in. He said that he frequently bred from the father and the daughter, and the mother and the son. This is not what I consider breeding in-and-in; for the daughter is only half of the same blood as the father, and will probably partake, in a great degree, of the properties of the mother.
Page 409 - I did not believe this to be the case, but this table shows that there is some foundation for the opinion. In order fairly to try this, the cows who calved before the 260th day, and those who calved after the 300th, ought to be omitted as being anomalous cases, as well as the cases in which twins were produced ; and it will then appear that, from the cows whose period of gestation did not exceed 286 days, the number of...
Page 198 - The lambs thrive, wear a beautiful appearance, and complete the joy of the breeder. He thinks that he has achieved a new cross-breed insuring great improvement, and requiring thenceforth only careful selection to perpetuate by propagation among themselves the qualities which he has in view. But he has reckoned without his host. For no sooner are the lambs weaned, than their strength, their vigour, and their beauty begin to decay as the heat of our summer increases. Instead of growing, they seem to...
Page 209 - ... are perpetually breaking out, yet, unless the characteristics and conformation of the two breeds are altogether averse to each other, nature opposes no barrier to their successful admixture ; so that, in the course of time, by the aid of selection and careful weeding, it is practicable to establish a new breed altogether. This, in fact, has been the history of our principal breeds.
Page 179 - Mr. Wilde, whose observations included the whole of the deaf and dumb population in Ireland, states that " ninety-eight deaf and dumb persons — sixty males and thirtyeight females .... were married. In eighty-six instances — fifty-four males and thirtytwo females — only one patient was deaf and dumb ; from the marriage of these, two hundred and three children resulted, among whom there was but one instance of mutism, a male, in the county of Limerick. Six instances have been recorded of the...
Page 367 - Animals that have been imperfectly nourished during growth, have their bones disproportionately large. If such deficiency of nourishment originated from a constitutional defect, which is the most frequent cause, they remain weak during life. Large bones, therefore, generally indicate an imperfection in the organs...
Page 30 - ... remarkable of the many examples known to me, is that of a family where four out of five children, otherwise healthy, became totally blind from amaurosis about the age of twelve ; the vision having been gradually impaired up to this time. What adds to the singularity of this case is the existence of some family monument long prior in date, where a female ancestor is represented with several children around her, the inscription recording that all the number were blind."* But not only are structural...
Page 50 - George had only four children; there were two girls with six fingers and six toes; there was one girl with six fingers and five toes on the right side, and five fingers and five toes on the left side, so that she was half and half.
