TESTIMONY OF CHARLES A. DOREMUS. 227 



milk ; I made another experiment and I took milk which I knew 

 was pure, a milk which stood high and which stood low and mixed 

 them in equal quantities, and again the calculated average of specific 

 gravity was at fault, the resulting specific gravity by experiment 

 was one degree below the calculated average. 



Q. Then from the table presented this morning of those 11 

 samples the deduction of 101 and something is not a true method 

 of arriving at the result ? A. It is perfectly impossible to state 

 what the average specific gravity of mixed milks will be by 

 figures. 



Q. Would the different quantities of milk have something to do 

 with it ? A. A great deal to do. 



By the COURT Q. What quantities of milk did you buy? A. I 

 mixed equal quantities. 



Q. I mean what quantities did you originally buy ? A. I sent 

 out and bought a pint of each milk. 



Q. Did you test them by the lactometer ? A. I took a fraction 

 of a pint of each. 



Q. After you tested each ? A. Then I mingled them in equal 

 quantities. 



Q. You tested each quantity of milk, that is the parcels of milk 

 that you bought, with the lactometer ? A. I did, sir. 



Q. Now, if you had added to each of the parcels of milk you 

 bought two gills of water and put in your lactometer, then after 

 adding it, would not that fact affect the gravity? A. Certainly. 



Q. The quantity being a pint and then say two gills of water 

 added to the pint, that would make a pint and two gills after the 

 water was added ; can you tell about how much those two gills of 

 water would have reduced the specific gravity of a specimen of 

 milk ? A. If I took a sample of milk standing at 120 and a sample 

 of milk standing at 105 



Q. You have got a given quantity of three different milks, 'all at 

 different places or at the same place, you keep them separate, you 

 test the specific gravity of each by the lactometer ; one shows so 

 much and the other so much ; you add two gills to each, and now 

 you put in your lactometer at a temperature of 60, what will be the 

 result ? A. They will all be lower in specific gravity undoubtedly. 



Q. About what ratio of the lessening of the specific gravity would
