THE AllMY HORSE. 83 



In the horse there is no disease of wliicli au exact diagnosis 

 is so important as that of o-huulei-s. 



In order to correctly dia<!:nose obscure cases (tliose witli no 

 outward symptoms) Ave must resort to the use of nudlein. 

 This is a liquid, the injection of which will cause a reaction 

 (rise in temperature) in glandered horses apparently enjoying 

 the best of health. 



Treatment. — This disease is not only contagious to horses, 

 mules, and men. but is incurable in all alike; therefore, the first 

 step, when a suspicious case presents itself, is to isolate the 

 animal, and as soon as it is proved that glanders exists, the 

 animal should be killed at once and the carcass burned. Every- 

 thing in the way of partitions, mangers, feed boxes, buckets, 

 and all stable utensils must be burned, and the stalls and sur- 

 roundings thoroughly disinfected. Chloride of lime 8 ounces, 

 in 1 gallon of water, makes a good and efficient disinfectant. 

 "With this solution all parts of the stable in which the affected 

 animal stood must l)e thoroughly washed. 



TETANUS LOCKJAW. 



(Plate XVI.) 



Tetanus is an infectious disease, the specific cause of which is 

 a bacillus or germ which, in most localities, is found in abund- 

 ance in the superficial layer of the earth in gardens, around 

 buildings, stables, etc. 



The disease, when present, always follows a wound, more 

 especially one j)roduced by a nail puncture. 



The germ will not develop in the presence of oxygen ; conse- 

 quently, all punctured wounds of the foot should be freely 

 opened to admit of the introduction of air, as well as to allow of 

 thorough cleansing with an antiseptic. This preventive treat- 

 ment is generally successful. 



In warm countries, especially in tropical climates, cases of 

 tetanus are much more frequent than in cold regions. 



Si/mptom-'<. — Tetanic spasms (spasmodic or continuous con- 

 tractions of the muscles) appear, as a ruk'. in the muscles of the 

 neck and head ; thence they extend to the shoulders, trunk, and 

 extremities; or the stiffness may start in the region of the in- 

 jured organ or member.
