admittedly cause isolated cases here as elswhere. 
Dr. A. H Baker, of Chicago, viewing the disease from a 
distance, attributes its wide prevalence in the west to bites and 
lough handling by other horses when in pasture. Dr. WanM, 
of Pennsylvania, observing the disease in the extreme south¬ 
west attributes it to rolling on stones due to the torments of in- 
sects. 
But these reasons do not explain the sudden appearance of 
the diseases ,n a large per cent, of horses over a certain area and 
its disappearance again in the course of a few years. 
In Montana it prevails very extensively now, some cases in 
unbroken animals on smooth ranges devoid practically of seri¬ 
ous insect pests. But it is more common in small bands of 
orses kept in pastures in the valleys, not worked, ridden or 
stabled, and having no perceivable reason for suffering from any 
unusual number of traumatisms—yet it will suddenly appear in 
two or three or even six or eight horses in one small band, in 
some as poll-evil, in others as fistulous withers and not infre- 
quently both appear at once in the same animal, or one may 
closely follow the other. Both show a very marked tendency to 
spontaneous recovery through suppurative processes. It occurs 
m the stable, too, as well as in the field, and I have seen poll- 
evil and fistulous withers appear simultaneously in isolated 
horses kept in good stables, with good care.

A PRACTICAL USE OF GUTTAPERCHA IN VETERINARY DENTAL 
SURGERY. 
By R. C. Moore, D.V.S. 
A paper read before the Missouri Val ley Vet erinary Association, October 3, 1894. 
For some years past I have successfully used Guttapercha in 
certain dental operations in a manner which I have never found 
any account of in our literature or other sources. So I thought 
it might be of interest to the profession.
