REMOVAL OF A TUMOUR FROM THE PENIS. 15

I cannot conclude this paper without expressing a hope that it 
will lead to a still more careful and extensive examination of the 
blood in various diseases than has hitherto been attempted. The 
microscope may become as important an instrument to the patho- 
logist, and even to the medical practitioner, as the stethoscope. If 
my results should be confirmed, it is hardly too much to expect 
that some important discovery, particularly in diagnosis, may be 
made by a patient investigation of the blood in many malignant 
diseases, such as cancer : it is not long since the urinous fever, as 
it is called, was found to depend on the accumulation of urea in 
the blood. 
REMOVAL OF A TUMOUR FROM THE PENIS OF A 
BULL. 
By Mr. HICKMAN, Shrewsbury . 
Mr. MEREDITH, of Uppington, in the county of Montgomery, a 
highly respectable farmer and a great agriculturist, purchased a valu- 
able bull of the pure Hereford breed, for forty-nine pounds. In the 
early part of last autumn he observed an enlargement round the end of 
the sheath, and a great deal of discharge from it. He had the parts 
well washed every day for some time ; but the discharge did not 
decrease or the swelling get less. He then called in a veterinary 
practitioner from Welshpool, who ordered a solution of sulphate of 
zinc to be applied daily, which was continued about two months, 
without any benefit to the animal. 
Mr. M. then requested me to come to his house and examine 
the parts, which I did on the 26th of December last. On making my 
examination, I discovered an enlargement upon the end of the 
penis, about the size of a walnut, and the external surface very 
much resembling the shell : it was remarkably tender, and when the 
bull was loosened out of his box to a cow he did not shew his 
usual desire, nor did he ever attempt to draw his penis. I told 
Mr. Meredith the only mode of relief would be to remove the 
substance by means of the knife. Mr. M. had a very great ob- 
jection to this, because he fancied it would render him incapable 
of serving the cows, and he would then be a great loser, after gi ving 
so large a price for him. In this opinion he was strengthened by 
several farmers who were present. I repeated, that I could do 
nothing that would be of use in any other way than the removal 
of the tumour. 
Mr. Meredith consulted the gentlemen present, and it was finally
