Up to the 15th there was no visible change. Each day the animal 

 ate part of its food. 



On the i6th the condition was graver. Temperature 39"8° C. ; 

 pulse 52 ; respiration 28. Mechanical pneumonia from passage of 

 food into the trachea was feared. Auscultation and percussion of the 

 chest revealed nothing abnormal. The laryngeal region was slightly 

 painful on pressure. The animal refused most of its food. 



From the 17th to the 20th, three and a half fluid ounces of alcohol 

 were given daily in the drinking-water, and three antiseptic fumigations 

 made. The symptoms persisted, and were accompanied by attacks of 

 coughing. 



On the 2ist there was trifling double-sided muco-purulent dis- 

 charge ; the submaxillary glands were swollen and sensitive ; the 

 temperature 39*6° C. 



On the 22nd discharge was more abundant ; the pituitary mem- 

 brane was deep red. The submaxillary swelling had become fluctuat- 

 ing. Temperature sg'S*^ C ; respiration 22 ; pulse 56. The abscess 

 was opened, and the cavity irrigated with carbolic solution. 



Next day the general condition had improved. The neck and 

 head were more freely moved. The animal ate all its food with the 

 exception of a little hay. Temperature 39*2° C ; respiration 28 ; 

 pulse 78. During the next few days the last symptoms of sore throat 

 disappeared, and the tonic contractions became less and less marked. 



On the 28th there was still slight stiffness of the ears and tail. ' 



On the 30th cure was complete. 



191, A ten-year-old entire horse, entered hospital February 3rd, 

 1897. For the previous three weeks a wound caused by the collar 

 had existed on the upper part of the neck. On the 3rd February the 

 animal worked during the whole morning, but towards two o'clock the 

 driver noticed signs of stiffness about the limbs and difficulty in 

 breathing. He took it to a veterinary surgeon, who diagnosed tetanus. 

 The animal was brought to Alfort during the evening. 



State on Examination. — On its arrival symptoms of tetanus were 

 clearly marked. Walking was difficult, the hind limbs especially being 

 affected. The neck was stiff, the head extended, and the tail elevated. 

 There was slight trismus. Temperature 38*3° C. No other wound 

 except that on the neck could be discovered. 



Treatment. — The patient was immediately placed in a dark box, and 

 the wound disinfected with 5 per cent, carbolic solution and tincture of 

 iodine. Three and a half ounces of sodium sulphate and one and a 

 half ounces of sodium bicarbonate were given in the drinking-water. 

 Milk ad libitum was allowed. The horse ate all its food, though masti- 

 cation was difficult. 



Next day the condition had become slightly worse. The breathing, 

 which had previously been normal, was rapid and short. Temperature 

 38*4° C. The same treatment was continued, but in addition eight 

 ounces of '8 per cent, salt solution were subcutaneously injected. This 

 was repeated during the following days. From the 5th fever ceased. 



On the 9th slight improvement was noted. Movement was less
