110 TESTIMONY OF HENRY MORTON. 



Q. What kind of salts are found in milk? A. Salts of lime, soda ; 

 I do not recollect the list of them. 



Q. Are there many ? A. No, those are the principal ones. 



Q. Can you give the specific gravity of the milk of any animal 

 other than the cow ? A. There is no specific gravity of milk of any 

 animal, each lot of milk will differ a little. 



Q. The milk of the lower animals, say the mare, the sheep and 

 the dog, is that on an average lighter in specific gravity or heavier, 

 than cow's milk ? A. My impression is that on an average there is 

 very little difference. 



Q. Do you recollect whether it is heavier or lighter ? A. No, I 

 never attempt to remember such details ; they are easily accessible 

 in books ; I look there if I want them, 



Q. Can you state in these various animals or any two of them 

 liow the ingredients vary in the milk ? A. Not from memory.

 A. I am a resident of Hoboken, New Jersey. 



Q. Have you ever tested New York milk or what you knew to 

 be New York commercial milk with the lactometer ? A. I have not. 



Q. Then how can you testify as you did on your direct examina- 

 tion, that if the commercial milk for sale in New York City is at 90, 

 at 60 Fahr., it is adulterated with water, if you have no acquaintance 

 with New York milk ? A. Simply because commercial milk, whether 

 in New York or in Philadelphia or anywhere else, I fully believe is 

 essentially the same thing. 



By the COURT Q. By commercial milk you do not mean milk of 

 cocoanuts or the milk of mares, but milk of cows ? A. Yes, sir. 



By COUNSEL Q. I understand you to say that butter is not 

 strictly a nutritious portion of milk, is that correct ? A. That is 

 my belief. 



Q. Why is it there is it placed there for ornament ? 



(Objected to ; objection sustained ; exception.)

 York city from which the butter has been removed is forbidden by 

 an ordinance of the Board of Health ? 



(Objected to ; objection sustained ; exception.) 



Q. You mentioned frozen milk in your direct testimony ; have 

 you ever tested that ? A. I have.
