MR. SEWELL’S INTRODUCTORY LECTURE, 1827. 41 
has given complete relief, and rendered a useless member 
very tolerably useful, by dividing the flexor tendons, the limb 
being first paralysed by cutting through the nerves. 
Several Members have distinguished themselves by the intro¬ 
duction of remedies. Sulphate of Zinc in solution is strongly 
recommended by Mr. Newport in quittor, in place of employing 
the cautery and the violent caustics which do so much harm: 
Mr. S. has found it very effectual. Mr. Wright, of — in Nor¬ 
folk, has used Hellebore ivith the greatest success in chronic 
diseases. He does business for Mr. Coke of Norfolk. He 
appears to have unravelled the secret in regard to its effects:— 
viz. that he never exhibits it until the animal has been well 
purged, and then he gives it without danger of inflaming the 
stomach and intestines, by which it has in some instances prov¬ 
ed fatal. Mr. Percivall has praised it as being useful in lower¬ 
ing the pulse, remitting it if you find that it does harm. We 
have made trial of it without observing the same effects. 
Within the last four years Mr. S. has been enabled to add 
to the stock of veterinary discoveries by adding a remedy for 
the glanders. Although there are practitioners that condemn 
this, more,” says Mr. S. bear me out: I have a horse that has 
been cured, now, four years. Many of the Profession have 
attempted to accomplish this by the medicine in the solid 
, form; but the same quantity which, so given, would inflame 
the stomach and bowels and destroy the animal, may be ex¬ 
hibited innocuously in a state of solution; and it succeeds 
best when the solution contains some mucilage, as gum arabic.” 
As a general dose Mr. S. recommends 3 vi. dissolved in a 
quart or three pints of fluid. He commonly suffers the animal 
to drink before, and some with advantage also allow him to 
drink after, the exhibition of the medicine. Given in this 
mode, the copper is not found to nauseate the animal or take 
him off his appetite. In fact, the secret (if there be any) con¬ 
sists wholly in giving the medicine in a fluid instead of a 
solid form. The old, diseased, or emaciated subject Mr. S. 
seldom makes any attempts on. He could decide in the dark 
' whether a horse affected with glanders was curable or not, and 
by the pulse alone. If it was 45 in a minute Mr. S. would 
say that the subject had diseased lungs: he can also tell by the 
pulse whether the lung is hepatized or not. 
Another state of lung, besides hepatization, is the tuberculat- 
ed. Here is a specimen of the miliary tubercles. (Showing 
a drawing.) These little tubercles suppurate and by coalesc¬ 
ence form large abscesses which discharge their contents 
through the bronchia: the horse is then considered as glander-
