At 30 days after beginning of treatment the strangles had 
subsided, bare traces remaining, while the effects of the odon- 
tome had almost wholly disappeared. The bulging of face had 
almost completely vanished, discharge from sinus had ceased, 
the trephine opening had closed and the foal left the infirmary 
in excellent general health and in better flesh than at the 
beginning of treatment. The recovery is apparently permanent 
and complete, leaving no noticeable unsoundness or blemish. 
The cyst wall, upon microscopical examination, presented on 
its outer side an appearance identical with the lining membrane 
of sinus, while inside it was lined with a firm, thin opaque white 
corrugated membrane. Its thickness varied, but generally was 
about 1-8 and 3-16 inches in diameter, soft and flexible at most 
parts but at others somewhat cartilaginous, and in places ex¬ 
hibited a hardening, indicating some movement toward the 
formation of dental tissue. 
MODERN ADVANCES IN SCIENTIFIC SURGERY. 
By L. A. Thomas, D.V.S., Atlantic, la. 
A Paper Read before the Iowa State Veterinary Medical Association. 
During the past few years a complete reformation has been 
gradually taking place in the science of surgery; conditions and 
methods handed down from generation to generation have 
become obsolete; many which but ten years ago were advo¬ 
cated as necessary to the maintenance or restoration of health 
have been completely discarded from the annals of modern 
surgery, and are now looked upon as injurious or detrimental to 
successful surgical interference. 
We have arrived at one of those epochs in the history of 
veterinary surgery from which a departure is taken, either in 
relation to its practice generally, or in the development of some 
special department. Among the most important of these 
epochs, so far as the general improvement in veterinary surgery 
is concerned, are those marked by the appreciation of the rules
