have done honour to any station ; who, unawed by the difficulties 
by which they were beset, came forward to contend with these 
difficulties, and nobly surmounted many ; and this their writings, 
&c. testify. 
To whom, then, is due what has been done but to these men here 
alluded to 1 But, can a few men of learning, here and there, ac- 
complish that which in a bod}' they might 1 To whom do we look 
to realise our future hopes in the profession but to those who are 
now entering it 1 Then, is it not to be desired that something be 
done to aid in realising these hopes, let the instrument be ever so 
feeble ! We grant that numerous are the evils which have been 
rooted out ; but we should bear in mind this useful maxim, “ never 
eradicate an evil without planting a virtue in its stead.” The 
time ought to be nearly arrived when the veterinary profession 
should be viewed as one that had acquired strength, that those 
who nutured it in its infancy might now take their rest, as it 
were, transmitting the care of it to their junior brethren. Every- 
thing must have a beginning, “ Arbor virga fuit.” The veterinary 
profession has had its beginning, or rather its regeneration, and 
that we may say within this century : it has had its difficulties, 
and those numerous ones : some have been overcome, some remain 
to be overcome. It is, Sir, then with the hope that this subject 
may be taken up by those in whom the power rests as one grand 
object that would tend to lessen these difficulties and enhance the 
value of the profession, that has induced me to trespass (I fear too 
long) on your time : the only excuse I can offer is, that I am what 
I subscribe myself, 
A devoted Friend to the Veterinary Art. 
SINGULAR MORBID CONDITION OF THE PLEXUS 
CHOROIDES. 
Dear Sir, — ALONG with this you will find enclosed a diseased 
specimen, which I have procured from the brain of an old pony. 
The mass appears to consist of cartilaginous granules, which are 
all embedded in the substance of the plexus choroides. The spe- 
cimen I send you is a longitudinal section of one-half of the mass, 
from the left ventricle. More particulars I will send you soon. 
Your’s, truly, 
W. Haycock. 
Huddersfield, 13 Nov. 1847. 
*** Many thanks for the specimen. The particulars of so rare 
and curious a case will be looked for with interest by the 
Ed. Vet.
