Aphorism II, 



If milk he put up in a dijhy and allowed to ft and till it 

 throws up cream, that portion of cream which rifes 

 jirft to thefurface is richer in quality y and greater in 

 quantity y than what rifes in afecond equal portion of 

 time J and the cream that rifes in thefecond interval 

 cf time is greater in quantity and richer in quality 

 than that which rifes in a third equal fpace of time ; 

 and that of the third than the four thy andfo on, the 

 cream that rifes decreafes in quantity y and declines in 

 quality continually y as long as any rfes to thefurface. 



My experiments not having been in this cafe 

 made with fo much accuracy as in the former, I 

 have not been enabled to afcertain the difference in 

 the proportion that takes place in equal portions of 

 time i but they have been fo often repeated as not 

 to leave any room to doubt the fad y and it will be 

 allowed to be a fa6l of no fmall importance in the 

 management of the dairy. It is not certain, how- 

 ever, but that a greater quantity of cream may upon 

 the whole be obtained from the milk by taking it 

 away at different times, but the procefs is fo trou- 

 blefome as not to be counterbalanced by the in- 

 creafed quantity obtained, if 'indeed an additional 

 quantity be thus obtained, which is not as yet 



fully certain.
