 would, almost to a certainty, be transmitted to descendants. 



"These remarks, with regard to breed and parentage, apply to 

 the selection of the bull, which, as experience demonstrates, acts 

 like the cow in transmitting the milking qualities which distinguish 

 the breed and stock. 



DIGESTIVE ORGANS. 



"These organs have a powerful influence on the exercise of 

 all the functions, and particularly on the secretion of the milky 

 glarfds. Where the digestive organs are defective, good milk 

 cows are rarely met with. 



"A good state of the digestive organs is evinced by the fol-

"Animals possessing these anatomical and physiological prop- 

 erties, eat well, drink much, and if they are properly fed, make 

 much blood, and yield large quantities of milk. 



RESPIRATORY ORGANS. 



"The respiratory organs complete the system of nutrition. 

 The object of the lungs is to bring the substance furnished by 

 the food into contact with the air, and make it capable of nourish-

 form, and a healthy condition of the organs of the chest, are 

 necessary to the production of much milk. 



"Their ability to fulfill their functions is evinced when they 

 are large, and lodged in a spacious cavity ; in other words, when
