ing ail open air life does not invalidate this position but merely 

 shows that other pathogenic conditions may be too potent to be 

 overcome by this hygienic one. 



A liberal allowance of sound grain is essential to success, even 

 in the case of patients sent to pasture. Those that have recovered 

 or improved at pasture, should be retained in the country and on 

 no account returned to the same city stables in which they con- 

 tracted the disease. Even in the country a different stable should 

 be secured if possible. 



Any food that has manifestly contributed to the disease, should 

 be withheld (bran, millet, musty or fermented food or that drawn 

 from particular fields). 



Overwork must be forbidden, and indeed any work at all dur- 

 ing the active stage of the disease. The victim should also be 

 withdrawn from breeding, at least until it has fully recovered the 

 normal consistency of its bone. 



In cases aggravated by cold or wet, or which show the rheu- 

 matic propensit}^ to shift from place to place, sodium salicylate in 

 ounce doses several times a day may appear to benefit, and as a 

 germicide this may be tried on all cases. Salicin, salol, or phen- 

 acetin may be used as substitutes. Where the disease has been 

 largely localized, blisters have appeared to be beneficial. 



Phosphates and phosphorus have been lauded b}' German 

 veterinarians, but in other hands, and when the morbid process 

 was active they have proved useless, or even hurtful. Bone dust 

 or phosphate of lime or soda may be freely used at any time and 

 appears to act as a general tonic, beside supplying lime and phos- 

 phoric acid wliich may possibly be availed of for bone nutrition. 

 Phosphorus and phosphorated oil in excess always softens the bone 

 and much more so when this process is already excessive. In 

 small doses (gr. \ to ^) and after the process of rarefaction has 

 ceased, it is valuable in hastening bone consolidation and fitting 

 the patient to return to work. 



Bitters, iron and other tonics are valuable in improving the 

 general tone and indirectly the bone nutrition. 



Cary had prompt improvement in connection with intravenous 

 injection of barium chloride once a week for four weeks, and ^ 

 oz. doses of sodium salicylate thrice a day. It remains to be seen 

 whether or not this is generally applicable.
