72 TESTIMONY OF CHABLES F. CHANDLER. 



statement, or guess, or evidence, to the effect that for every three 

 degrees of the thermometric temperature milk decreases two degrees 

 in specific gravity ? 



(Objected to.) 



A. There may have been in some sample that he tested. 



Q. Is that a safe general scale or average ? A. It is not, nor is 

 any other scale safe, nor is any used by the inspectors of the Board 

 of Health. 



Q. Doctor, you demonstrated yesterday, did you not, that skim- 

 med milk stands much higher on the lactometer than milk which is 

 pure or comparatively pure ? A. It does. 



Q. Now, if your inspectors come across skimmed milk, will they 

 not pass it by as pure ? A. Not necessarily ; they detect it by the 

 fact that it stands high on the lactometer ; looks blue and thin to the 

 eye and tastes peculiarly, and they take samples if necessary and 

 have them analyzed. 



Q. In the Kneib case were you not asked the question : " In case 

 he," meaning the inspector, " came across skimmed milk he would 

 invariably pass that by as good milk"? and did you not answer, 

 " Yes, sir, most undoubtedly " ? A. I think, very likely ; I have 

 learned a great deal about skimmed milk and cream since the 

 indictment in that case. 



Q. Did you not make that answer ? A. I did ; I had not inves- 

 tigated at that time the question of whether it would be easy to 

 detect skimmed milk by the means of the lactometer and the 

 senses. 



Q. But that was about a year ago ? A. It was, I think, about a 

 year ago. 



Q. At that time you testified, did you not, that you had been a 

 chemist about twenty years ? A. I had. 



Q. That you had made the subject of milk analysis a specialty ? 

 A. Yes, sir. 



Q. Your lactometrical standard was the same as it is now ? A. 

 I never was after skimmed milk, and I never had been accustomed 

 to experiment with skimmed milk ; I testified I was not aware it 

 was possible to detect skimmed milk ; I made that reply. 



Q. Then within the past year you have made the discovery that 

 the evidence of the senses will enable the inspectors to tell the
