Live stock : a cyclopedia for the farmer and stock owner including the breeding, care, feeding and management of horses, cattle, swine, sheep and poultry with a special department on dairying : being also a complete stock doctor : with one thousand explanatory engravings . it isill some foals. One haunch may pass into the inlet before the other, how-ever, and thus facilitate the passage. AVith the cow the mechanism of parturition in this presentation to that in the mare, Saint-Cyr shows, from actual measurementsof cow and fcetus, that the head of the calf can easily pass into the inlet,owing to its less diameter; and that the principal difficulty is encounteredby the foetal thorax, which is slightly larger in every sense than the inlet. The bicoxo-femoral diameter of the croup slightly exceeds the bis-iliacdiameter of the pelvis; but it is possible that the pelvis of the calf, beingmore cartilaginous and supple than that of the foal, may be submitted to aslight temporary compression. It is to be remarked, however, that theprogress of the calf through the pelvis must be more protracted than thatof the foal, owing to the greater length of the maternal pubic symphysis,and the more considerable extent of the pelvic walls, as well as the peculiar.

And, as we haveseen, such is really the case, the duration of parturition being shorter inthe mare than in the cow. With regard to the other animals, the same remarks will apply. Wemay just note that with the common-bred bitch, which has a more or lesselongated muzzle, when fecundated by a dog of the same conformationand size, and which in due course brings forth from five to eight young,there is usually no difficulty in delivery. The conical form of the muzzleof the puppies, and the softness of their tissues, permits their enter
