124 TESTIMONY OF BENJAMIN SILLIMAN. 



necessary to go into that detail unless the counsel desires it. Says 

 Quevenne, " We place under our eyes a table covering a period of 

 eleven years, 1843 to 1854, upon which are recorded the degrees by 

 the lacto-densimeter and the lactoscope of 103 milks of the 

 purity of which I am sure, they having been drawn from the cow 

 before my own eyes," or words to that effect ; see the results ; mini- 

 mum, 28.8 ; maximum, 36.4; mean, 32.2. .Now, sir, without occupy- 

 ing more of the time of the Court, I will simply add that in the close 

 of this very valuable memoir, which, I think, upon the whole is by 

 far the most valuable contribution we have received to the litera- 

 ture on the subject of milk, there is a resume of 103 analyses. It 

 will be observed that the columns here relate to the date at which 

 the milk was produced, the place of their production, the kind of 

 cow, the age of the cow, the quantity that is furnished by each cow 

 per day, whether milked in the middle of the day or in the evening, 

 and then the degree of density by the lacto-densimeter, and they 

 give the numbers, running from 1 to 103 consecutively ; it is not 

 necessary to read them, but I will give you the resume ; the pages 

 are 192 k> 196 inclusive, the resume being upon the last ; my infer- 

 ence from this is that the statement which I made in my testimony 

 before recess is abundantly supported in the fact that these very 

 competent witnesses appear to rely exclusively upon the lacto-dens- 

 imeter for determining the density of milk. 



Q. Can you refer to any other passages in this book which sus- 

 tain the method or a method similar to that used by the Board of 

 Health in this city ? A. I regard the whole book as responsive to your 

 question. Will you allow mi to add one word of explanation, lest 

 I should be conceived by the honorable counsel or jury to not fully 

 state the matter ; I do not wish to conceal the fact that there are 

 expressions in Quevenne upon the lacto-densimeter in which he 

 states that the instrument as a scientific instrument is not as per- 

 fect as might be desired to meet all the questions of' caseine and 

 sugar, etc., and he criticises the instrument ; doubtless the wit- 

 nesses on the other side will call attention to that ; I will take the 

 time of the Court to do it now if it is desired ; I will read the whole 

 of it to you if you like. 



Q. Will you refer to the bottom paragraph on the first page and 

 translate that ? A. I translate it as follows : " If the guilty ought to
