504 GENEKAL DISEASES. 



eggs mixed in it, and by ale or stout, if necessary. If the bowels 

 act freely, the linseed oil may be discontinued, and the turpentine 

 mixed with gruel and eggs as a drench. If constipation be present, 

 administer enemas of Wiarm water. Give green meat and any 

 wholesome food the animal may like to eat. Keep him warmly 

 clothed and nurse him carefully. If the breathing becomes 

 difficult, tracheotomy may be performed, but only as a last re- 

 source ; for the tissues, if wounded, have a great tendency to 

 slough during this disease. For the same reason, the swellings 

 should not be punctured unless with the object of relieving marked 

 distress in breathing. 



Haemoglobinuria {Azoturid). 



DEFINITION.- — A condition characterised by the excretion of 

 dark-coloured urine, excitement, and violent and painful spasms 

 of the croup muscles, usually after a period of good feeding and a 

 few days' rest. 



CAUSES AND NATURE.— In England, this disease is almost 

 always due to work after a period of idleness during which the 

 patient has been liberally fed on corn. I have seen it principally 

 among highly-fed cart-horses, and have never observed it in 

 animals which are regularly worked. Many Continental writers 

 regard cold as the chief cause of this complaint ; although this is 

 not the case in Great Britain, where the cold is much less severe 

 during winter. Mr. Holmes, M.R.C.V.S., of Bourne ("Veterinary 

 Record " for 29th June, 1901), reported the case of a horse which 

 had been turned out on a piece of grass-land that was not worth 

 more than £8 an acre, and had become affected. He was certain 

 that it was not feeding in this case, for the animal had not had 

 any corn for a long time, but it was so bad, that it could hardly 

 turn round in its box. In the same journal, Mr. R. W. Clarke, 

 M.R.C.V.S., remarked that " it is easy to understand why this con- 

 dition should be so common amongst, horses in training either for 

 racing or hunting, and on a cold windy morning it is not an un- 

 common occurrence for several of these cases — which are known to 

 racing men as ' setfast ' — ^to come under the notice of the veterinary 

 surgeon. Fortunately these cases are not of the most severe 

 nature, and being promptly attended to answer in a short time to 

 treatment. When this condition is observed in agricultural horses 

 — which is a comparatively rare occurrence — it will generally 

 happen during the time that corn is being harvested and the horses 

 are allowed to eat at the sheaves of corn while the waggons are
