REPOET OF THE VETERINARY SURGEON. 311 



In relation to treatment, there is little to be said. Various 

 systems of medication have been faithfully tried, but to no 

 effect; its progress marches steadily on in spite of every min- 

 eral and herb that the land affords, or at present known. 



In tlie chronic forms, where the greatest constitutional 

 prostration occurs, stimulants are surely indicated, but their 

 effects arc very transient. Arsenic and strychnine have been 

 recommended as very efficacious in the treatment of the local 

 affection ; and I would suggest the free use, externally, of 

 carbolic acid for the same purpose. Thus, when every medic- 

 inal remedy has been tried, the mortal canker of this equine 

 plague may still exist, then the pole-axe or the leaden ball is, 

 of course, our last resort. Such should be tlie treatment of 

 every well marked case of this disease. 



And though we cannot cure such afflicted horses, yet we can, 

 by judicious management, prevent others from being exposed 

 to this contagion in one of these infected stables. When a 

 barn has thus become contaminated, no creature of the equi7ie 

 family should be placed within its tainted walls until it has 

 been thoroughly renovated. The floor of the stall, as well as 

 the crib, and the partitions, if old and considerably worn, 

 should be replaced ; but if the material is comparatively new 

 it may be overhauled and planed, and thus rendered harm- 

 less. Where an iron crib is used, or any metallic implement 

 employed about such a horse, it should be carefully cleansed 

 with a weak solution of mineral acid. A strong solution of 

 potash should be effectually applied to the hitching posts, 

 beams, and otlier places wliere such a horse has been recently 

 tied ; and the whole stable whitewashed. Tlie free use of 

 carbolic acid, chloride of lime, and other disinfectants, is of 

 great importance in such a stable. 



Another contagious malady, no less malignant, and one of 

 far more importance to the health of the community, has 

 made its appearance upon the western borders of our state, 

 and is scientifically known, from the organs which it attacks, as 



PLEUROPNEUMONIA, 



or a disease of the lungs and their surrounding membranes, and
