THE COMPOSITION OF THE FEEQING STUFFS 



was determined by analyzing a part of them, and by reference to 

 the table in Bulletin No. 4, page 16, for the remainder. The re- 

 sults of the analyses are shown in the following table : 



THE COMPOSITION OF THE RATIONS 



is shown in detail in the next table, which gives the amount of 

 food used for a cow weighing one thousand pounds. Each ration 

 is designated at the top of the column by a letter (a, b, c), which 

 serves to distinguish it in the succeeding tables where the effect 

 of the food on the butter is shown : 



THE NEXT TABLES 



in order give the details of feeding-periods, with the ration fed, 

 the date of taking the sample, the group or cow, and composition 

 of the butter. The figures for volatile acids signify the number 

 of cubic centimeters of deci-normal barium hydroxid solution, 

 which are equivalent to the volatile acids in five grammes of butter- 

 fat. The iodine number means the number of parts of iodine ab- 

 sorbed by one hundred parts of butter-fat. (This explanation of the 

 figures is given for the satisfaction of other chemists who may 

 read this article, and is as clear as can be given in a few words.)
