son), although lysol was originally recommended, and the more 
common antiseptics may be efficient enough when these are not 
at hand. I place the udder for disinfection and infusion upon 
a white oil-cloth, because I have experienced that cows some¬ 
times sudden y react during the infusion with a hind foot 
throwing up dust, which must be guarded against most scrup- 
u ouslv. Then I introduce the milking-tube into one teat after 
another while an assistant is pouring the iodide solution into the 
umiel, dividing it equally into four parts for the four teats I 
also have him cover the funnel with filter-paper to prevent con- 
tammation of its contents. The massage of the udder during 
and after infusion I perform now myself, because I consider it

treatment for future statistical material.

culosis, which we hope you will distribute to cattle owners who 
are your friends and patrons. We are making an effort to en- 
courage the more general private application of the tuberculin 
test. Much practical experience in its use, as well as the testi¬ 
mony ot others having larger experience, makes us firm believ- 
ers m its value to dairymen, not only in purifying their herds, 
but Mso of pecuniary advantage to them in making it possible 
tor them to weed out tuberculous cattle early in the course of 
ie disease before they have become such a prolific source of in- 
rection as to contaminate an. entire herd, resulting in great loss 
to the owner. Besides this there is a further advantage greatly -
