*Teat cups fell off while milking. 
It will be seen from these results that there was no observ- 
able difference with the two kinds of cotton used in these tests. 
If considerable care had not been taken to remove the moisture 
before aplying the absorbent cotton the showing would un- 
doubtedly have been markedly in favor of the ordinary kind. 
On account of its mechanical advantages and markedly lower 
cost there is every reason why ordinary cotton should be used 
in the filter cups on a milking machine and so far as these 
studies have gone there are no known disadvantages in its use. 
The count obtained from Nora on November 11 shows the 
result of the accidental falling off of the teat cups during the 
milking process. Since these results were obtained as the 
result of abnormal conditions of milking they were not included 
in the averages. ,

While the most important points in the handling of the 
milking machine seem to group themselves logically around
