species: for Mr. Clark states that this part varies much in form.), the
mammae differ greatly in shape in different breeds, being elongated in the
common goat, hemispherical in the Angora race, and bilobed and divergent in
the goats of Syria and Nubia. According to this same author, the males of
certain breeds have lost their usual offensive odour. In one of the Indian
breeds the males and females have horns of widely-different shapes (3/102.
Mr. Clark 'Annals and Mag. of Nat. Hist.' 2nd series volume 2 1848 page
361.); and in some breeds the females are destitute of horns. (3/103.
Desmarest 'Encyclop. Method. Mammalogie' page 480.) M. Ramu of Nancy
informs me that many of the goats there bear on the upper part of the
throat a pair of hairy appendages, 70 mm. in length and about 10 mm. in
diameter, which in external appearance resemble those above described on
the jaws of pigs. The presence of inter-digital pits or glands on all four
feet has been thought to characterise the genus Ovis, and their absence to
be characteristic of the genus Capra; but Mr. Hodgson has found that they
exist in the front feet of the majority of Himalayan goats. (3/104.
'Journal of Asiatic Soc. of Bengal' volume 16 1847 pages 1020, 1025.) Mr.
Hodgson measured the intestines in two goats of the Dugu race, and he found
that the proportional length of the great and small intestines differed
considerably. In one of these goats the caecum was thirteen inches, and in
the other no less than thirty-six inches in length!
