The results are excellent by both methods, and, as is seen, not 
only were practically all the globules above two divisions of the 
micrometer scale in diameter removed in the cream, but also by — 
far the larger proportion of those present whose diameter was 
above one division of the scale were also recovered in the cream, 
since the ratio'in number of globules less than one division in the 
skim-milk was to the number of those between one and two. 
divisions as 100 to 67, while the ratio in the normal milk was as 
100 to 186, thus proving that even if some of the globules below 
one division were recovered in the cream —a most unwarrantable 
supposition — there were recovered nearly two-thirds (sixty-four 
per cent) of those globules between one and two divisions in 
diameter, and practically all of those larger. 
It will also be observed that while there was upon an average 
half as many fat globules in the skim-milk as in an equal volume 
of normal milk, the skim-milk contained only four per cent as 
much total fat as was present in the full milk. 
These results are entirely in accord with the facts set forth in 
the table giving the “Per Cent of Total Fats in the Different Sized 
‘ Globules,” where it was shown that the Holderness milk con- 
tained but .3 per cent of its fat in globules of less diameter than 
one division of micrometer scale, and 24.7 per cent in ‘those 
globules from one to two divisions of the scale in diameter;
