 particular attciition to the cleansing and disinfecting of the 

 gutters. For freciuent flushing of the gutters use a satu-

 in this case it is important to observe the precautions cited 

 under heading No. 5, using a separate apparatus for each 

 bull. 



APPENDIX NO. 2. 



A PRELIMINARY REPORT UPON FORAGE-POISONING OF 

 HORSES (SO-CALLED CEREBROSPINAL MENINGITIS). 



By Leonard Pearsox, B. S., v. m. d. 



The disease or horses commonly known as cerebro-spinal menin- 

 gitis has long been supposed to result from the ingestion of food 

 that has undergone fermentation or putrefaction or that has become 

 mouldy. The evidence in favor of this view has, however, never 

 been of a direct but only of a circumstantial nature. While the 

 disease has in many instances occurred on farms and in stables 

 where horses were fed on mouldy or musty grain or ground feed, 

 damaged hay or spoiled ensilage, and it has been assumed that such 

 foods produced the disease, there has always been a lack of proof, 

 first, that these foods were poisonous, and, second, that some other 

 influence had not produced the disease. This absence of proof is 

 due to no lack of efforts to fix the responsibility on suspected food- 

 stuffs. Experiments have been made in large numbers in which 

 suspected materials have been fed to horses in the attempt to pro- 

 duce the disease called cerebro-spinal meningitis, but all of these 

 trials have resulted negatively. So far as the literature of this 

 subject shows, cerebro-spinal meningitis, so-called, has never been 

 produced artificially or under experimental conditions.
