Several facts are shown by these analyses which may not be 

 new, but which are worthy of special mention. 



(1.) The order of richness of the milk is Jersey, Ayrshire and 

 Holstein, the Jersey leading the other two breeds by a large dif- 

 ference. 



(2.) It is noticable that the milk of two cows for a time fell 

 below what is considered in some states the legal standard, and 

 would be condemned by an inspector as watered milk. 



(3.) Analyses made of milk of three of the cows from one to 

 two weeks after parturition showed it to be much richer than it 

 was a month later, when it dropped to the point of least solids. 

 In this decrease the Jerseys did not share. From the point of 

 least solids there was a gradual increase in the percentage of solid 

 matter up to the time of going dry, excepting with the Jersey 

 "Agnes." This increase was not of fat alone, or casein alone, but 

 took place with all the solids. 



(4.) The lowest percentage of solids found for any cow was 

 with the Holstein Jansje, 10.12 per cent, on July 2.5th, 1888, and 

 the highest was with the Jersey Ida, 17.63, on July 16th, 1889. 

 The percentage of fat in the two cases was 2.29 and 6.71 

 respectively.
