202 TESTIMONY OF ROBEBT OGDEN DOEEMUS. 



sugar, and does not that vary in different milks ? A. The amount 

 of sugar is one of the most uniform of all the constituents of 

 milk. 



Q. Does it not range from 2 to 6 per cent? A. This chart 

 expresses it, yes, sir 2.8. 



Q. It varies from 2.8 to what ? A. Up to 6, that is according 

 to this series of tables taken from Wurtz' Dictionary of Chemistry, 

 the last edition ; the work is still incomplete ; yonder chart will 

 give you the specific gravity of the serum. 



Q. Do I understand then that the maximum that that table pre- 

 sents is the percentage of 6 of sugar ? 



(Objected to.) 



A. Yes, sir. 



Q. Did you hear the citations read from Wanklyn, upon the 

 examination of witnesses for the prosecution as to the necessity of 

 fixing a standard for milk ? A. Well, I believe I heard them read, 

 but I did not pay particular attention to them, for that author gives 

 such sweeping denunciations of the lactometer, that I was surprised 

 to hear any reference made to it. 



Q. Have you found this in reading Wanklyn, " In dealing with 

 milk supply on a large scale, we are little concerned with the 

 possibility of single animals giving abnormal milk, and need only 

 concern ourselves with milk of normal quality, all departures from 

 the standard being looked upon as sophistications." A. I heard 

 that. 



Q. Do you agree with him or not ? A. I agree with him. 



Q. You do agree with him ? A. Yes, sir ; this is the work, your 

 Honor, in which it says, " From a careful consideration of the whole 

 subject, I am convinced that one of the most necessary steps to be 

 taken in milk analysis is to abandon the use of the lactometer." 



Q. Are you familiar with this Dictionary of Hygiene, by 

 Professors Tardieu and Blythe ? A. I know of it. 



Q. I suppose one of the works referred to by you ? A. No, sir ; 

 I referred to another one of Tardieu. 



By the COURT Q. You have said that the percentage in pure 

 milk of water as distinguished from the other constituents of milk, 

 ranged from 80 to 90 ; now that being, so far as you have stated, 

 the range of quantity, is not the specific gravity of a given specimen
