74 VETERINARY LECTURES 



observation, I have met with it in certain breeds of horses, and have 

 generally traced it to hereditary causes, and have usually found it 

 associated with heart affections. 



142. Treatment of rheumatism is not very satisfactory, but 

 when much pain and constitutional fever are present, ounce doses 

 of sulphate of magnesia or sulphate of soda, along with \ oz. of 

 nitrate of potash, may be given night and morning, in a mash, with 

 2 to 3 drachms of salicylate of soda at noon, or quinine in 1 to 2 

 drachm doses twice a day ; if the pain is very acute, hypodermic 

 injections of morphia are useful. 



143. Cripples, or Crockles, is a rheumatic affection of the 

 muscles from which cattle sometimes suffer, and which is generally 

 known by these names, most frequently occurs on strong, undrained 

 land or on sour, mossy ground. The animal suffering arches its 

 back and walks as if on stilts ; it becomes hidebound, milk and flesh 

 disappear rapidly, and the beast is very fond of chewing bones, 

 stones, and foreign bodies. A change of pasture, with doses of 

 10 ounces linseed oil and 1 ounce of turpentine, twice or thrice 

 weekly, I have found to answer best in such a case. Dressing the land 

 with lime or salt is also to be highly recommended. In some farm 

 buildings young bulls under twelve months old are occasionally 

 affected in a similar manner, and I attribute it to the arrangement 

 of the boxes, their imperfect sanitation and ventilation, but more 

 particularly their ground floor, which is frequently found to be laid 

 with old red sandstone flags, having bad drainage, and with ground 

 damp evaporation. In these cases I always recommend that the 

 floor be pulled up, the soil dug to the depth of 8 or 10 inches, 

 then filled with stones, bricks, sand, etc., and paved on the top with 

 the old-fashioned blue cobble or fluted stable bricks. Dry wooden 

 portable beds, raised 4 to 6 inches, also answer admirably. The 

 animal also ought to have the run of a large yard or paddock in dry 

 weather, while half the quantity of oil and turpentine mentioned 

 above should be given. Two-drachm doses of salicylate of soda 

 may also be given once or twice a day.
