peace with every one ; but it is high time that that language 
should be discarded by the best of us, which would disgrace the 
lowest, and to which the lowest should not, cannot submit. 
I shall not ask Mr. Charles Clark how long it is since he dis- 
covered that The Veterinarian was so vile a publication. 
The November number of it contains a case of his, and appended to 
that was a promise that I should be furnished with a series of 
them. Let them come; — non unde sed quid is my motto. 
One thing more I must say ; — I think that the reference to 
the unsent reply of Mr. Bracy Clark to me was not quite in good 
taste. 
I feel it imperative on me to publish this correspondence ; for 
while I am replying to you, I am saying that which I wish every 
one clearly to understand. 
I have the honour to be, Sir, 
Your obedient servant,

LECTURE IX. 
The Medulla Oblongata , and the Nerves from it. 
Having taken a rapid sketch of the diseases of the nerves 
proceeding from the sensitive and motor columns of the spinal 
cord, we should complete our review of the pathology of the 
sensorial system of animal life, by considering the natural and 
morbid structure and functions of the organs of smelling, sight, 
hearing, and taste. This, I acknowledge, would be the regular 
course ; but I shall not be much out of order, if I complete our 
examination of the spinal cord before I leave it ; and that will 
give me the opportunity, some months sooner than I otherwise 
could, of addressing you on a malady of too frequent occurrence, 
and on which you have again and again pressed me to lecture ; — 
namely, rabies, a disease principally of the organic system. 
The Medulla Oblongata.— The spinal cord commences at the 
posterior edge of the pons varolii, or tuber annulare ; and that 
portion of it which is contained within the cranial cavity is 
termed the medulla oblongata. It is of an oblong form — broad 
and thick towards the tuber, and diminishing in width and thick- 
ness as it approaches the foramen magnum. There is no part of 
the nervous system in which there exists so essential a difference
