MENINGITIS 149 



in amounts varying according to the weight of the pa- 

 tient. I give half an ounce of Fowler's solution and a 

 dram of potassium iodid at each dose for a twelve-hun- 

 dred-pound horse. Beginning with the Fowler's solu- 

 tion, I have the attendant administer a dose of the iodid 

 three hours later; again three hours later the arsenic 

 solution, and so on every three hours from early morning 

 to late at night. I keep this up until an ounce of the 

 potassium iodid has been given ; then I continue Fowler's 

 solution alone every four or five hours. 



"With this treatment I have had some remarkable results

 eral condition, such as the appetite, temperature, and so 

 on. Neither do I worry about the position of the patient ; 

 if recumbent, I have him turned over every three or four 

 hours. 



As a prophylactic measure, hexamethylenamine should 

 be administered to other horses in the stable where a ease 

 exists. This drug can be relied upon to prevent the de- 

 velopment of this disease if it is used before infection has 

 occurred. From one to two drams should be given in a 

 pail of water twice daily. 



As it is quite generally conceded that the infectious 

 matter gains entrance to the body in feed or drinking 

 water, both should be changed if possible. On general 

 principles all cases of this disease should be handled as 

 are those of transmissible diseases, even though doubt 

 exists about the transmissibility. 



In exceptional instances the infecting agent seems to 

 be so weak or inactive that the symptoms produced are 

 very mild and diagnosis is difficult. In such cases, if 

 one is not familiar with the vagaries of this condition, 

 the cases are easily mistaken for influenza. Doubt can 

 usually be dispelled, however, if the horse is excited. 

 Cracking a whip and threatening the patient with it, will
