monstrosities. In reflecting on the varieties, which every 
practitioner must have observed, he will find that, however 
strange these forms may be, all are reconcileable with the law of 
excess or defect — defects of which the Anidia are the simplest 
examples. They exhibit none of the ordinary forms of 
animals, yet, from the origin and the perfectness of the

[We remember to have received, a few years ago, from a

reached the College did not allow of its being preserved. 
If we remember rightly, it was given birth to by a cow, and

AND SURGERY. 
Part II. 
By John George Dickinson, M.R.C.V.S., Boston. 
The diversified nature of my cases in these contributions 
is such that the adoption of a special method in their descrip- 
tion is out of the question. I cannot well classify my mate- 
rials, and therefore I give preference to the insertion of the 
cases of longest standing in my note book. I have engaged 
in another work since I left London, and that is to keep a 
statistical account of the diseases prevalent in those parts 
to which my daily travels extend, with observations on the 
several agencies which influence their production. This, as 
may be imagined, takes some time to fill up, but from it I 
expect, at the expiration of each successive year, to draw 
most valuable information. Meanwhile I offer no systematic
