needle through the skin and through the space between the 
rings for about one inch. Should the first attempt be unsuc¬ 
cessful, do not attempt to force the needle through tracheal 
cartilage. Raise or lower the point of the needle, use slight 
pressure, when suddenly the needle will enter the trachea. 
Now, very slowly empty the contents of the syringe into the 
trachea. While emptying the syringe the animal will continue 
the attempt to swallow. If it make rapid attempts at swallow¬ 
ing you will know that the fluid is entering the lungs too rap¬ 
idly. Coughing and sneezing will result and the fluid will be 
thrown up into the mouth and nose. It is advisable while 
giving the injection to have the animal chew some hay. It 
attracts its attention and lessens the tendency to cough. The 
head should continue to be elevated for about five minutes. On 
account of the corrosive action of iodine, the syringe and needle 
should be immediately washed after use. The following is the 
report of the cases as they progressed, with the history of each 
case:

previously \ legs oedematous 5 no appetite \ sero-mucous dis¬ 
charge from both nostrils, tinged with blood. The animal was 
unable to perform the labors which were imposed upon him. A 
veterinarian was called, who pronounced it a case of glanders. 
I saw the patient on the seventh day after the owner first 
noticed that his horse was sick. When first seen it presented 
all the typical and characteristic symptoms of purpura hsemor- 
rhagica. I might also add that he presented a pitiable sight, 
being unable to move ; legs swollen to such a degree that the 
skin cracked, through which oozed a bloody serum. The ster¬ 
num and abdomen were extremely oedematous, as was also the 
left side of the cheek and nose. He was breathing through the 
right nostril. Prostration extreme; temperature 105°; pulse 
90, weak and small; respiration 30, short and quick. From the
