T. F. WINCHESTER. 
subject cannot be said to be spoken of at all, and in one in¬ 
stance, the author, in referring to it, states that it does not 
occur in this country (England), although it appears quite 
frequently in Germany. 
In referring to the journals of the present day (in English) 
one can almost count the articles on this subject on his hand, 
and that being the case, 1 came to the conclusion there must 
be a few veterinarians that are not aware of the importance of 
this subject. 
The examinations and investigations 1 have made in this 
subject, with the able assistance of Dr. J. M. Parker, of Haver¬ 
hill, only again very forcibly brings to my mind the fact that 
we must not take too much for granted, but make original in¬ 
quiry for ourselves. It is not necessary that all the work 
shall have to be done with the microscope. It is not a fact, 
that in making post-mortem examinations we only look for a 
condition that, in our opinion, would cause death, and never 
once think enough about it to look and try to find out if there 
is a tangible cause for the effect produced. How often have 
we made a post-mortem examination and have been unable to 
find lesions that would satisfactorily explain the cause of 
death, when, possibly, by a closer examination, the cause 
might have shown itself? 
t ^Certainly there must be cause for this laxity in our post-j 
ortem examinations, and I am inclined to think that, per¬ 
haps, the principal cause may be laid at the door of our in¬ 
structors, in a great many instances; but oftentimes the 
pressure of business is the cause. 
Can we afford to allow the coming generations of veterina¬ 
rians to look back upon us as not having the same powers of 
observation as the generation gone before us? Why is it that 
the Continental literature is so much more instructive than 
the rest? The articles on record regarding this malady are 
interesting, but, with the exception of Dr. W. L. Williams, 
they are confined to unusual cases, where the parasites are 
very numerous, or the lesions gross. In Dr. W. L. Williams’ 
article the several cases he cites are in animals that had been 
in pasture and the season wet, thus favoring, according to the
