Cream-test bottles. Special forms of bottles have

89. The Winton cream bottle. The ercam-test bottle 

 devised by "Winton/ (fig. 32), has a neck of the usual 

 length, and of sufficient width to measure 

 30 or 50 per cent, of fat. The scale of 

 the neck is divided into parts represent-

 each, but readings of a quarter 

 of a per cent, can easily be esti- 

 mated. Such readings of 

 cream tests are sufficiently ex- 

 act for most commercial pur- 

 poses. This form of cream bot- 

 tle will be found very conven- 

 ient in making tests of com- 

 posite samples of cream. 



Cream test bottles of a small 

 bore are greatly to be preferred 

 to those with wide necks (fig.

 rate readings to a quarter of a per cent. 



Other forms of cream-test bottles which 

 allow the testing of 50 or 55 per cent, cream 

 have been placed on the market during late 

 rears by some manufacturers. These bot-
