3d. The milk is richer than in the ordinary cow, and consequent- 

 ly yields more butter; the butter is always of a yellow color, and 

 has a taste and flavor superior to that of a cow not castrated. 



There are results of many other experiments given; they all unite 

 in saying that the cow should not be operated upon, until her lacta- 

 tive powers are fully developed, say at the age of 6 years, and 

 about 40 days after calving, when she will continue as long as the 

 owner chooses to keep her, the same flow of milk, her feed and 

 other things being equal. Instances are mentioned of cows having 

 yielded the same quantity for 6 or 7 years. 



Particular directions are given for performing the operation, which 

 some better linguist, than I must translate, as they are full of tech- 

 nical terms. 



To persons who keep cows for milk only, and fo whom the time 

 they are dry and suckling their calves, is a loss of seldom less than 

 three months, an operation of this kind upon their animals would 

 increase their value greatly. 



As the subject was entirely new to me, I have troubled you with 

 it. If you think it worth while to mention it before the Institute, 

 perhaps some of the members may say something about it. The 

 theory, which is obvious, is to me very plausible. 



With great respect, I am, &c., 



HUGH H. BOWNE.
