TESTIMONY OP ROBERT OGDEN DOREMUS. 199 



Q. Is the milk of the lower animals or of some of them of much 

 heavier specific gravity than that of the cow ? 



(Objected to ; objection sustained ; exception.) 



Q. Doctor Doremus, on which side of this question are the 

 greatest number of authorities, the question as to the sufficiency of 

 the lactometer to test the adulteration of milk by water, as to the 

 lactometer being a sufficient test for the adulteration of milk by 

 water, on which side of that question are the most authorities? 

 A. They are antagonistic to it and some of them, as I have stated, 

 express, in the most vigorous terms that their language is capable 

 of allowing, their opposition to its use, in the manner which has 

 been described. 



By the COURT Q. Do they express opposition to the use of the 

 lactometer for the purpose of ascertaining the specific gravity ? A. 

 To its sole use ? 



Q. For the purpose of obtaining that simple fact ? A. No, sir ; 

 I misunderstood you that is the adulteration of milk. 



Cross-examined by Mr. PRENTICE : 



Q. Doctor, you have mentioned the most important authorities 

 which give the view that you have just expressed concerning the 

 determination concerning the specific gravity of milk, have you 

 not ? A. I have mentioned a few. 



Q. Have you mentioned the most important, or have you left 

 the most important uninentioned ? A. I think I mentioned some 

 of the most important. 



Q. Are there any as important as those that you have mentioned ? 

 A. There are many others ; I gave a list which I was excluded 

 from reading. 



Q. I will ask you, Dr. Doremus, are the reports of Doctor Yoelc- 

 ker, the chemist of the Royal Agricultural Society of England, upon 

 the examination of milk, its supply and adulteration, authorities on 

 this question ? A. They are, sir. 



Q. Has Doctor Voelcker in a paper published in the year 1875, 

 in England, expressed this opinion, that " a great many experiments 

 have led me to the conclusion that within certain limits specific 

 gravity is the most trustworthy indicator of quality ? " A. He has ;
