52 TESTIMONY OF CHARLES F. CHANDLER. 



in your direct examination as sustaining the lactometer , you stated 

 you were familiar with the standard European and American autho- 

 rities on the subject ; I want you to give the names, as far as you 

 can, of those you referred to ? A. May I consult this book ? 



Q. Yes, sir ? A. I have read the Milk Journal for a number of 

 years ; a year or two, at least ; I have examined Wanklyn, HassalL 



Q. What is the full title of those books ? A. The first is the 

 Milk Journal, an English journal. 



Q. What year ? A. Somewhere in the year 1870 ; I have for- 

 gotten the exact date ; Du Lait et de I' Allaitement, by C. Marchand, 

 Milk Analysis, by J. A. Wanklyn. 



Q. What is that edition of Wanklyn? A. The last edition, I 

 presume ; I am not quite sure about that ; I will qualify my answer 

 when I have given the titles of these books ; Food, and its Adultera- 

 tions, the last edition, by Hassall; Gmelin's Ghemie. 



Q. What edition is that ? A. The last German edition. 



Q. Do you recollect the year ? A. No ; because it is in succes- 

 sive numbers, and it has been ten years in publication ; Watts' Dic- 

 tionary and supplements. 



Q. Which supplements, Doctor ? A. Both ; C. Mueller's Anleit- 

 ing zur Pruefung der Kuhmilch. 



Q. When was that published, and what is the edition ? A. It 

 was the first and the last edition ; I have examined them both. 



Q. Is that a New York publication ? A. Published in Germany ; 

 in Switzerland, rather ; I have further read all the papers that have 

 appeared in the Jahresberichfc der Agrikultur Chemie ever since it 

 was published, I think, about ten years ; I have also read everything 

 on the subject of milk that has been published in Wagner's 

 Jahresbericht der Chemischen Technologie, and in the Jahresbericht 

 der Thier Chemie ; these journals contain abstracts of all papers 

 published in Germany on these subjects ; I have forgotten whether 

 your question involved my discriminating with regard to the exact 

 opinion which these authors on the lactometer hold. 



Q. Any other authorities ? A. These are the chief names; I 

 could give them all, if desired to look through my notes carefully. 



Q. If you could name any others, I would like them ? A. I have 

 read Yon Baumhauer ; I would state that many of these books that 

 I have alluded to contain resumes of all the authors on the subject;
