 at regular intervals till the laft, which was filled with 

 the dregs of the ftroakings. Thefe were each 

 weighed, the weight of each cup being fettled fo as 

 to afcertain that the quaiitity of milk in each was 

 precifely the fame; and from a great number of 

 experiments, frequently repeated with many diffe- 

 rent cows, the refult was in all cafes thus : 



The quantity of cream obtained from the firft 

 drawn cup was, in every cafe, much fmaller than 

 from that which was laft drawn ; and thofe between 

 afforded lefs or more, as they were nearer the be- 

 ginning or the end. It is unneceffary here to fpe- 

 cify thefe intermediate proportions j but it is proper 

 the reader fhould be informed, that the quantity of 

 cream obtained from the laft-drawn cup, from fome 

 cows, exceeded that from the firft in the proportion 

 oi Sixteen to one. In other cows, however, and in 

 particular circumftances, the difproportion was not 

 quite fo great ; but in no cafe did I find it fall Ihort 

 of the rate of eight to one. Probably, upon an ave- 

 rage of a great many cows, it might be found to run 

 as ten or twelve to one. 



*xdly. The difference in the quality of the cream, 

 however, obtained from thefe two cups, was much 

 greater than the difference in the quantity. In the
