of the members, &c. He then proceeded to make a few 
remarks on the physiology of the brain, and also on the 
difference of the symptoms between disease cf that organ 
and disease of the stomach. Towards the close of his remarks 
he spoke as follows : 
“ Briefly reviewing what has been advanced as the phy- 
siology of that part of the brain I purpose alluding to, at the 
outset it will be found, 
“ 1st. That the encephalon, viewed as a whole, appears to 
represent a chain of centres, each exerting a certain de- 
finite amount of influence over the functions of the mind 
and body. 
“ 2d. To four of the aforesaid centres we have, and with 
apparent justice, defined their functions or offices to consist 
in presiding over the intellectual , the volitional , the sensitive t 
and the visional actions. 
“3d. That the centre of intellectual actions apparently 
resides in the convolutions of the cerebrum, and the fibres 
which pass from and by which it is joined to the corpora 
striata and the thalami optici. 
“4th. That the centre of volition is resident in the corpora 
striata, and other parts of the medulla oblongata, unnecessary 
here again to enumerate. 
“5th. That the thalami optici, in connexion with other 
parts of the medulla oblongata, constitute the centre of 
sensation. 
“ 6th, and lastly. That the quadrigeminal tubercles are the 
centre of vision. 
“ With these remarks upon the physiology of the brain, 
and my premises being received, it shall now be my endeavour 
to turn them to account, and to show how far such physio- 
logical knowledge will afford us service when diagnosing 
between stomach staggers and tumours in the brain of cattle; 
and in order to do this, I purpose giving the history of a case, 
with its symptoms, and then bringing our physiological 
knowledge to bear in order to elucidate these symptoms. 
“ Case , Sfc. — I was requested to inspect an aged milk-cow, 
of the Ayrshire breed, the property of Wm. Montgomery, 
Esq., Cockhill, Dundonald. I was informed she had been 
under the treatment of a veterinary surgeon for recurrent 
stomach staggers for upwards of four months. 
“ Symptoms . — The animal was standing in a loose box, very 
much emaciated, although a good feeder, and appeared wild 
and uneasy at the approach of strangers. When made to 
walk, she staggered , carried the head to the right side, and 
turned towards the left . On close inspection I discovered 
that she was labouring under paralysis of the right optic
