SPECIAL NOTICE. 



After the chemical work was completed of which this 

 Bulletin gives an account, and the matter was prepared 

 for the press, a circular was received at the office of the 

 Experiment Station from parties selling the fat-measure 

 used in this process, as well as the right to use it, under 

 a patent. On further inquiry it proved that such a 

 patent had been applied for. No mention was made of 

 this in the original article on the method, in the Jour- 

 nal of , Analytical Chemistry, and this circular gave us 

 the first intimation of any such patent claim. 



But even if the method is patented, it was decided, 

 after careful consideration of the matter, that it may be 

 no less useful to dairymen, and the issue of the Bul- 

 letin was therefore proceeded with. 



The fat-measure and the right to use it can be ob- 

 tained of A. Marshall & Son, 220 N. Fifth St., Phila- 

 delphia, Pa. All the other materials can be obtained 

 there also, and probably at about the price for the whole 

 outfit given on page 22 of the Bulletin,
