EDITORIAL. 
both by private and official labors, it becomes important to be 
acquainted witli the probability of errors that may be easily en¬ 
countered. To guard against such our readers will be interested 
in the article presented by Mr. Megnin on that special subject, 
to the Society of Biology of Paris. The characters given by the 
gentleman, as differential between trichina and individuals of the 
gender Spiroptera, which are commonly met in some lower 
mammalia and other lower classes of animals, will be read with 
interest. 
NEW OUTBREAK OF PLEURO-PNEUMONIA IN PENNSYLVANIA. 
From a recent communication we learned that contagious pleuro¬ 
pneumonia had been stamped out in Pennsylvania, and that the 
only danger of a new outbreak was from importation from other 
States, principally from Maryland. We were about registering 
this good news when we received from Dr. Gadsden, U. S. 
Veterinary Inspector, a paper from Philadelphia announcing the 
report of a new outbreak, which we reprint in the pages of the 
Review. To a certain extent Pennsylvania was placed like New 
York at the end of the last Commission ; the funds were cut short, 
hence the stopping of the good work, hence probably the new 
outbreak. 
This speaks for itself, and shows the error of considering a 
State free from disease, until sufficient time has elapsed to warrant 
confidence against all dangers and providing all necessary measures 
had been taken. This new state of affairs will not help us to get rid 
of the English restrictions. The best thing we can recommend 
to Pennsylvania is the creation of a veterinary bureau with proper 
veterinary officers. 
DR. E. von HERING. 
In our last number it was our sad duty to record the death of 
this celebrated veterinarian. To-day we have published from 
the pen of one of our correspondents a bibliography of the Doc¬ 
tor, whose life has been such a long series of labors and investiga¬ 
tions in behalf of the veterinary profession.
