size, generally weighing from forty to sixty stone, 

 although some have been known to weigh seventy 

 stone. Their form is shorter than the Lancashire 

 breed, and otherwise resemble them, except in their 

 want of horns. They fatten on the most valuable 

 parts, and their beef is finely marbled or mixed. 



MILCH COWS. 



Great differences are known to exist in the 

 quantity of milk which cows yield, as well as the 

 quality of the milk itself 



The short-horned and Ayrshire breeds give most 

 milk ; more cream is thrown up on its surface, and it 

 produces a greater proportion of cheese. Some persons 

 think the Alderney breed the best suited for dairies, 

 as yielding a great proportional quantity of milk and 

 cream, and also for consuming a smaller quantity of 

 food. The Suffolk duns are also remarkable for the 

 quantity and excellence of their milk. 



TUBERCULOSIS. 



The bodies of all animals are open to invasions of 

 a growth generally termed " tubercle," and no organ 

 is exempt. The human subject and cattle are especi- 

 ally liable to this invasion, and it is calculated that 

 tuberculosis proves fatal to 25 per cent, of the human 

 race, and invades from 25 to 50 per cent, of milch 

 cows. 



If we examine these tubercles as we find them in 

 the lung of the human subject, they are seen to be 

 little, round, hard, grey-coloured bodies, about the 

 size of a millet seed, and yielding no fluid when 

 crushed (miliary tubercle). In a more advanced stage 

 it is of a yellowish colour, and of the consistency of 

 putty or cheese (yellow tubercle).
