difficult ; the neck less stiff; the nostrils less dilated; while respiration 

 was slower and easier. The injections of artificial serum produced 

 considerable struggling, but nevertheless were continued until the 

 14th. 



From the 15th to the 25th treatment was reduced to daily adminis- 

 tration of four and a half ounces of sulphate and one and a half ounces 

 of bicarbonate ot soda. Improvement was slow. 



From the 25th to the 30th injections of artificial serum were re- 

 peated, but they caused such violent struggling that finally they had to 

 be suspended. Treatment was, therefore, again restricted to adding 

 sulphate and bicarbonate of soda to the drinking-water. 



During the early part of March improvement occurred more 

 rapidly, and by the loth recovery was complete. 



192. An eleven-year-old mare, entered hospital October 15th, 1897. 

 On the 25th September had fallen and injured the right forearm and 

 knee. On the 14th October symptoms of tetanus appeared. The 

 animal was brought to the school next morning. There was trifling 

 generalised muscular contraction and slight trismus. Temperature 

 was normal. The animal could still eat. 



Treatment. — Disinfection of the wound and of the knee and forearm 

 with 3 per cent, creolin solution, followed by tincture of iodine. Eight 

 fluid ounces of warm i per cent, salt solution were injected into the 

 jugular, five ounces of sulphate, and two ounces of bicarbonate of soda 

 were given in the drinking-water. In addition enemata containing 

 chloral were administered. 



During the next two days the condition remained stationary. 

 Respirations 20 ; temperature 38° to 38*4° C. The animal took gruel, 

 hay, and oats. Treatment as before. 



On the i8th the trismus was a little more pronounced. Tempera- 

 ture 38*2° to 38*5° C. Nine and a half fluid ounces of artificial serum 

 were subcutaneously injected. These injections, together with the 

 internal and local treatment, were continued until the 26th, on which day 

 improvement appeared. As the animal became difficult to approach 

 the enemata were discontinued. 



Until the 12th November a daily dose of i to if ounces of sodium 

 bicarbonate was given in the drinking-water, and from time to time 3 to 

 5 ounces of sodium sulphate. At the date mentioned recovery was 

 complete. The animal left hospital on the 15th November. 



193. A twelve-year-old gelding, entered hospital November 29th, 

 1896. Had been castrated four months previous!}- ; one of the wounds 

 had become sinuous. A week before, the animal's left hind pastern 

 had also been injured by a fragment of glass. On the 29th November 

 the owner noticed that the horse moved with difficulty. The head was 

 extended on the neck, the tail was elevated, and the limbs were stiff. 



State on Entry. — The patient showed symptoms of acute tetanus. 

 Tonic muscular contraction was intense and generalised ; at rest the 

 limbs were stretched out on either side, and during movement were 

 advanced without being flexed. The tail was lifted; the head
