THE PRINCIPLES OF BOTANY. 
Mr. F. Bulley, F.R.C.S., saw the disease in situ , and 
suggested the use of the actual cautery in preference to the 
knife, and kindly assisted me in the examination of the parts 
removed. At the request of Mr. — Moxhay, I attended, as 
a visitor, two monthly meetings of the Pathological Society, 
held at the Royal Berkshire Hospital in this town, when the 
morbid specimens were introduced to the notice of the 
members of the Society. My thanks are due for the courtesy 
with which they were received, and the suggestions which 
were offered. 
In ‘ Histological Demonstrations/ by Messrs. Harley and 
Brown, the articles on scirrhus and encephaloid are peculiarly 
interesting to any one meeting with cancer, and the book 
should be in the possession of every veterinary surgeon. I 
agree with its authors in the opinion that surgical operations 
often accelerate the appearance of secondary cancer in parts 
distant from the original seat of the disease, and that its re- 
currence is especially characteristic of its malignancy. The 
case before us proves the truth of this, although there is every 
probability that infiltration would have taken place without 
the operation; and even supposing such would not have 
occurred, I was compelled to remove the parts to enable the 
animal to be used by his owner. 
I also know of a case in the human subject, in which I 
assisted the operator a short time since, in which secondary 
cancer developed itself in the parotid and submaxillary glands, 
subsequent to the removal of a cancer from the point of the 
ear. At the moment of my writing the patient is past hope.

As we have examples of different kinds of fairy-rings in our 
home meadow, we commence this article with a description 
of them. 
In a survey of the rings of this field, made in 1869, we 
constructed a chart of more than thirty rings, more or less 
perfect in outline, and being very variable in size. 
At the present moment, however, we cannot make out 
more than half of the number of the previous year, but many 
of these possess a most perfect outline, but the rest appear
