. This distention acts like magic, and seems hardly to admit of
failure in securing a successful outcome.

It can not, however, be recommended as absolutely devoid of dangers and
serious complications. To get the best results it should be applied only by
one who has been trained in the careful antiseptic methods of the
bacteriological laboratory. Some readers will recall the case of the
injection of the udders of show cows at Toronto to impose upon the judges.
The cows treated in this way had the udders infected and ruined, and
several lost their lives. There is no better culture medium for septic and
other germs than the first milk (colostrum) charged with albumin and
retained in the warm udder. Already in the hands of veterinarians even the
Schmidt treatment has produced a small proportion of cases of infective
mammitis. How many more such cases will develop if this treatment becomes a
popular domestic resort, applied by the dairyman himself in all sorts of
surroundings and with little or no antiseptic precautions? Even then,
however, the losses will by no means approach the past mortality of 50 to
70 per cent, so that the economy will be immeasurable under even the worst
conditions. A fair test and judgment of this treatment, however, can be
obtained only when the administrator is trustworthy and painstaking, well
acquainted with bacteriological antisepsis and with the general and special
pathology of the bovine animal.

The necessary precautions may be summarized as follows:

(1) Provide an elastic rubber ball and tubes furnished with valves to
direct the current of air, as in a common Davidson syringe.

(2) Fill the delivery tube for a short distance with cotton sterilized by
prolonged heating in a water bath.

(3) In the free end of the delivery tube fit a milking tube to be inserted
into the teat.

(4) Sterilize the entire apparatus by boiling for 30 minutes, and, without
touching the milking tube, wrap it in a towel that has been sterilized in a
water bath or in live steam and dried.

(5) Avoid drawing any milk from the teats; wash them and the udder
thoroughly with warm soapsuds; rinse off with well-boiled and cooled water,
and apply to the teats, and especially to their tips, a 5 per cent solution
of carbolic acid or lysol, taking care that the teats are not allowed to
touch any other body from the time they are cleansed until the teat tube is
inserted. It is well to rest the cleansed and disinfected udd
