There will be a peculiar dropsical swelling and these patechial spots, or 

 it may show itself in connection with the eyes, and there may be blood 

 extravasation without external symptoms. It may affect the bowels, liver, 

 lungs, etc. The swelling is due to extravasation of blood. A peculiarity 

 of purpura is, that the swelling may disappear from one place and appear 

 in some other part, which is difficult to account for. The animal usually 

 stands, perhaps from difficulty in moving the limbs. It is necessary to 

 watch the case closely, for the flies will attack him, and he will be filled 

 with maggots. Sloughing may take place ; the entire sheath, or patches 

 upon the body may slough off, and there may be paraphimosis. If influ- 

 enza prevails, and you have swelling of the legs, examine very carefully. 



Treatment. — The duration of this diease is from eight to thirty days. 

 It generally takes about a month for an animal to completely recover. 

 Place in a comfortable place. Give chlorate of potash, not for any stated 

 properties, but from its action on the blood. If the bowels are costive I 

 recommend giving from one to two ounces of turpentine in six or eight 

 ounces of oil. Afterwards give as much as one or one-and-a-half ounces 

 of chlorate of potash during twenty-four hours ; give it in his water, as 

 there may be difficulty in giving a drench. Give, as a styptic, the tinc- 

 ture of the chloride of iron, once or twice a day, in doses of two or three 

 drachms. If the pulse is strong and the appetite good, repeat the tur- 

 pentine and oil in one or two days ; and I have seen cases where a pur- 

 gative was given with advantage, say five or six drachms of aloes, but 

 not if there is any other trouble with the bowels. Sponging the nostrils 

 may do good, according to the season of the year — cold water in the sum- 

 mer. Hot is sometimes used, but is not good, as it tends to encourage 

 the exudation of the blood. Local remedies are of but little benefit, for 

 the disease comes from an improper condition of the blood. Support the 

 system by nutritive diet : watch the case closely, and see that the animal 

 does not get too much to eat, as it might produce colic. If the pulse is 

 not very quick and no tendency to lung disease, I think exercise is of 

 benefit. It is good practice to move the animal away from the stable 

 where he has been kept. You may have to perform tracheotomy if the 

 animal is likely to suffocate, but in most cases, although you afford tem- 

 porary relief, the animal will not get along very well. 



After-Treatment. — Chlorate of potash and tonics, good food, regular 

 exercise, etc., and if the flies attack him, use carbolic acid, just to pre- 

 vent the flies from attacking him. It is liable to very sudden changes. 

 You may think he is doing very well, and the next time you see him he 

 will be very bad. You may use some styptic, as acetate of lead, etc. It 

 is not best to open up with a knife, but in exceptional cases it may be 

 necessary. 



Strang-les.— This is a very common disease among Canadian and 

 American horses. It is called strangles from a peculiar suffocating 

 breathing, and is known as strangles in most of our works. It is an 

 eruptive fever peculiar to the horse, and generally attacks him when 

 young, from two to four or six years old, but may be found in older horses. 

 Some call it a catarrhal disease. It shows itself by affecting the organs 

 of respiration more or less, and the formation of a tumor in the submax- 

 illary space. It is hard and small at first, but gradually enlarges and 

 suppurates. This tumour may form in other parts of the body, on the 

 point of the shoulder, in the groin, etc., and when it takes on this form 

 it is called irregular strangles. Most horses have it while young, 

 but some escape it. It is contagious, and many animals in the same 

 stable may become affected at the same time. It is said to attack the 

 same animal but once, but there are some cases that show that
