TESTIMONY OF EOBEKT OGDEN DOREMUS. 197 



Q. Is that more sure on the question of adulteration by water than 

 the lactometer ? A. It is. 



Q. Are you familiar with the authors upon milk ? A. I am, I 

 believe. 



Q. Will you name some of the best of them, or name a number 

 of them? A. Yon Baumhauer, Quevenne, Boucharclat, Hoppe-seyler, 

 Ambrose Tardieu, one of the most distinguished savants in his 

 department, Watts' Chemical Dictionary, Wurtz, the editor of the 

 French Chemical Dictionary, which is not yet quite completed, 

 Wanklyn, Hassal, Bloxam, Letheby, and many others I might men-
