longer than this ; they are all on the same principle ; they are 

 areometers ; if it is a heavy liquid 



Q. Are you able to swear that there is no difference ; are you 

 able to say positively that there is not a difference upon the scale 

 of degrees upon this lactometer ? A. I doubt if I could ; I have not 

 observed it critically. 



Q. Is it not stated that the smaller intervals on the hydrometer's 

 scale may always be subdivided into equal parts by estimation or 

 otherwise, without appreciable error ; is not that the rule laid 

 down? A. I know in Watts' Dictionary very distinctly that a 

 full page is devoted to the correction of these irregularities in the 

 measurements of instruments giving figures as to how much wider 

 they should be. 



Q. How many specimens of milk of cows did you take for ex- 

 amination of those which you have testified about in Orange 

 county ? A. Of those that I first spoke of? 



Q. How many were there ? A. I believe about a dozen. 



Q. And were there more than five of those that fell below the 

 standard? A. No, sir. 



Q. Only five ? A. No, sir. 



Q. And that lowest one that you have testified to to-day was 

 the milk of the black cow ? A. That was not obtained by myself 

 personally. 



Q. But the one you have mentioned ? A. As low gravity, 

 simply ? 



Q. That was the black cow, was it? A. It was. 



Q. How came you to go to Orange county? A. I was asked by 

 Mr. Lawrence if I would make an examination. 



Q. That is the counsel in this case ? A. The counsel in this case. 



Q. And have you been for several years employed by the milk 

 association ? A. I have not, sir ; at the time I went I was not 

 aware that there was a milk association in New York. 



Q. Who went with you ? A. Two gentlemen, one Mr. Pond, 

 an American gentleman, a most original character, and another, Mr. 

 Schaffer, whom I have since learned was president of the milk asso- 

 ciation, which I was not aware of at the time. 



Q. Did Mr. Pond belong to the milk association ? A. Not to my 

 knowledge ; it is an association, I believe, of Germans.
