That the toxins of various infectious diseases are eliminated with the mammary secretions when the gland is active is a well-known fact, and that these frequently prove fatal to suckling animals is also well known.

While the case recorded does not definitely set at rest the question as to whether the milk of animals affected With tetanus is innocuous to sucklings, still it may act as a more or less valuable contribution to the literature of tetanus, for the reason that in this particular instance the attack was a decidedly severe one. OBSERVATIONS ON PURPURA HEMORRHAGICA IN THE HORSE WITH ADDENDA OF ALLIED By Fred C. Mahon, M. R. C.

V. S. Recently encountering some bad cases of purpura hemorrhagic in two instances following upon bastard strangles, in another a seauel of influenza, and adopting follow in my experience I am afraid I cannot give a precise reply. Whilst -writing of Adrenalin and its use in purpura, let me quote a very able American writer, observer; and clinician '(vide "Veterinary Materia Dr. J.

H. King, of the Kansas City Stock Yards, states that he finds Adrenalin is a reliable means of diagnosing the presence of "heaves" (broken wind, asthma, emphysema of lung tissues). Even tho the horse has been drugged with stramonium or other sedative, he says "I noticed that upon injecting intravenously 30 minims of Adrenalin Chloride solution in i-ounce of normal salt solution the breathing became accelerated in about one minute, and if the animal was only slightly affected with the disease it would immediately show the double respiratory act, or double abdominal breathing, accompanied by the usual action of the costal muscles unabated for several minutes. I have used Adrenalin Chloride as a diagnostic agent for the past three years with the greatest confidence. In order to verify my diagnosis, I have kept "track of these cases, and have always found afterwards that I was correct." I refer to these notes, as it was by accident in using, the same in Case 2 of purpura in another aged mare on the farm where my thirty-year-old "nag-mare" had strangles, followed by purpura and broken wind setting in suddenly, that after the ii st injection of 90 minims of Adrenalin Chloride my patient's breathing became normal, and this condition remained so "for thirty-six hours approximately, and with the hemorrhagic infarctions, petechial spottings of mucous membranes, and edema, the broken wind was again noticeable.

This to my mind opens up a serious "question as to whether fraud is not possible by injections of horses prior to sale, and particularly if put to the crucial point. Post-mortem results and chemical analysis would not afford the practitioner or purchaser of a broken-winded horse much satisfaction, if any. Briefly, Case 1, a twelve-year-old mare (heavy van). Cardiac weakness marked; temperature, 98.6 F. pulse, submaxillary, -68 per minute, cardiac 90; both small, weak intermittent edema of all four legs, causing animal to remain a fixture in her stall.

Head pendulous for two days, and animal stupefied, forcing head into a corner, and remaining in this position for hours. Here adrenalin repeatedly used. Saved this case. In fact, I have only attended her for a week. Value originally knacker's price.

Today worth "20. a' line of treatment far remote from the orthodox, I. am induced to record the same, One subject was a thirty-year-old bay mare "which had not previously had a day's illness" according to the owner. Grazing on herbage already invaded by some army and other animals the mare had suffered severely from strangles febris oyogenica was evidently invaded by the poison, and to sucluan extent mat at one time I feared dissolution. The paroti-deal swelling, and resultant abscess after blistering and opening of the same, took on a bad ulcerative process, the cavity measuring 13 inches in circumference at one time.

Thruout the seizure the appetite was never remiss, and temperature did not exceed 104.3 F. In this case my treatment was by tonics, as acid hitro-hfdrochloric dil, solution of ammonium acetate, and infusion of gentian in scalded hav, chaff, corn, and In lieu of cantharides, or mercurial blister, I used repeatedly mustard oil, an agent I employ extensively. I give hypodermatically injections of strychnine and electuary of potassium iodide, belladonna, and glycerin.
