to be derived from the French authorities and from what range of 

 observation ? 



(Objected to as calling upon the witness to state the contents of 

 those authorities.) 



Q. From what range of observations reported in the best stand- 

 ard French writers upon the subject of milk and its tests has the 

 best opinion been derived about a fixed standard of milk and the 

 use of the lactometer ? 



(Objected to as calling on the witness to state opinions of others 

 and to discriminate between them ; objection overruled ; exception.) 



A. The tests reported are stated to be 6,000 by Quevenne and 

 the statement is made by Dr. Christian Mueller, the director of the 

 milk station in Thun, in Switzerland, who is considered an expert 

 in that business. 



Q. At what range of observations there ? A. In Switzerland 

 there are a number of observations ranging from twenty to forty at 

 a time, but I do not remember exactly in what proportion, yet I 

 remember that it is about such a proportion as ten. 



Q. Is the opinion that you have expressed according to the best 

 authorities in regard to the use of the lactometer for detecting the 

 watering of milk ? A. The lactometer is not an instrument to de- 

 tect small quantities of water in the milk within that scale. 



Q. I ask, is the opinion which you have already expressed as to 

 the use of the lactometer for detecting the watering of milk con- 

 sistent with the best authorities on this subject ? A. Yes, sir, the 

 lactometer is recommended by Mueller himself in consequence of 

 experiments by himself throughout Germany and other countries. 



Q. Is your opinion that you have expressed at variance with or 

 in accordance with the best opinion of the best authorities ? 



(Objected to ; objection overruled ; exception). 



A. I think it is. 



Cross-examined : 



Q. Now, Professor, won't you give us the names of the standard 

 authorities to which you refer ? A. Of standard authorities I might 

 name Fleischmann, Vogel, Mueller ; these are principally some of the 

 original investigators ; those who have compiled I have not taken 

 care of.
