REMARKS ON THE POREGOING CASES. 
Amongst some half dozen or more cases which have 
occurred in my practice where tumours have been found within 
the brain, or its substance has been interfered with by the pro¬ 
cess of diseased action, in connection with, or independent of 
abnormal growths, I have met with none where the organ 
was so extensively disorganised as in the instance of the black 
horse just related. Comparing these lesions, both with regard 
to the outward and physical indications as well as their in¬ 
ward morbid condition, with others in which the various 
parts have undergone extensive derangement, one cannot 
but feel greatly surprised to witness the few symptoms which 
mark the real amount of disease actually going on within 
in the latter; and the vast interference in such as the 
former, with the natural habits of the animal and func¬ 
tional arrangements where symptoms are exceedingly violent, 
and actual disease apparently trifling. We may be excused 
somewhat in the want of accuracv which characterise our 
* 
diagnosis of these diseases, probably by the nature, habits, 
and requirements of our patients, and the paucity of general 
information on the subject; but I am inclined to believe that 
by an attentive observation of the symptoms manifested during 
life, especially if the patient has been known for a lengthened 
period to the practitioner, with a careful examination of the 
affected parts after death, a great deal will not only be 
revealed thereby, but more will become of paramount im¬ 
portance. Certain morbid appearances will be seen to depend 
upon some unusual indications and physical signs, which as 
they reveal themselves under peculiar phases and conditions, 
may at least render an estimate more decisive if not absolutely 
perfect. In these particulars we must undoubtedly experience 
the value of association. At our periodical meetings the 
bringing forward of such accounts, which I have on this 
occasion attempted with, I must say, neither the erudition 
or the attainments which such subjects are known to require, 
but with sincerity, must be valuable. Coupled with this, we 
have valuable echoes which resound from the pages of our re¬ 
presentative journals, cheering us onwards as the career seems 
blighted and cloudy, dispelling as it were the. mists of doubt 
and uncertainty, and cordially assisting us by the publication
