32 TESTIMONY OF JOHN BLAKE WHITE. 



Q. What is the average gravity of cream ? A. 1.012. 



Q. What is that on the lactometer ? A. It will stand about 77. 



Q. Now, won't you state what the ingredients of milk are and in 

 what proportions ? 



(Objected on the ground that that is not material.) 



A. The ingredients of milk are water, butter, sugar, caseine, and 

 ash. 



Q. What are the proportions of each ? A. The maximum of 

 water is about 88 per cent. 



Q. What is the minimum ? A . The minimum I found 86 per 

 cent, in pure milk ; the sugar is 4 per cent., the butter about 3 per 

 cent., the ash 0.29 per cent., and the caseine 3.16 per cent. 



Q. Are you quite sure as to the correctness of those propor- 

 tions ? A. I have given you them as near as I can. 



Q. Let me call your attention to the proportion of ash, have you 

 not misstated that ? A. I should like to refresh my memory in 

 regard to the analysis. 



Q. By the COURT Do you mean the notes of the analysis made 

 by you. A. Yes, sir. 



COUNSEL I object to the witness being allowed to refer to his 

 notes. 



WITNESS Well, sir, I have found in one analysis .5 of ash, .and I 

 found .29 psr cent, in the specimen I analyzed some time ago. 



Q. What is the average quantity of ash ? A. I should say the 

 average would be near .50 per cent., if not a little more. 



Q. How many per cent, of water do you say the accused's milk 

 was adulterated with ? At least 15 per cent. 



Q. Now state what influence the temperature of milk has upon 

 its gravity ? A. The specific gravity of the fluid varies with the 

 temperature, because in chemistry fluids expand when warmer, and 

 their specific gravity is lightened. 



Q. To what extent does that exist ? A. I have found that to 

 vary. 



Q. How much ? A. From two degrees in specific gravity to 

 three in temperature, about that variance ; that is the greatest 

 amount of variance. 



Q. Do you always get milk up to the temperature of 60 Fahr. 

 when testing it? A. Yes, sir, I do.
