intensity of the palpitations; revulsive irritants applied to the 
skin, such as setons and blisters ; and antispasmodics internally ; 
the administration of two ounces of valerian root each day, and 
one ounce of purple digitalis mixed up with five or six ounces of 
meal. This sufficed to remedy the disease. Care was taken not 
to leave off this medicine too speedily when the beating of the 
heart ceased; but gradually to diminish the dose. Copious 
drinks of barley or marsh-mallows were given to the patient, 
whose bowels were also kept open. For the first few days no 
solid food was permitted, and after that only small quantities, 
which were progressively increased. 
5. Three horses, and a mare three months gone with foal, and 
aged from four, to twenty years, died in our infirmary of teta¬ 
nus ; two in August, one in September 1830, the third in April 
1831. The first at the end of two days, the second five, the 
third six, and the last eleven days. 
If we have not been so fortunate as to cure them, we have at 
least been able to study the divers parts of their organization, and 
seek out the lesions which this terrible disease leaves behind it. 
In these four subjects the sinuses of the dura mater, the su¬ 
perficial vessels of the brain, and those of the plexus choroides, 
were more or less injected ; a quantity of serum, more abundant 
than in the healthy state, was found in the large ventricles of the 
brain, and also on the cerebral surface. The consistence of the 
spinal marrow appeared more firm in two of these subjects, but 
it became spotted with red when an incision was made into it* 
In others the consistence did not differ from the healthy state. 
The arachnoid membrane of the brain in the one, and that of the 
lumbar region of the spinal cord in the other, had a red tinge, 
but which a maceration of about twelve hours in cold water quite 
got rid of. In one of these carcasses the spinal marrow had a sort 
of leaden tint, and was rather soft; and before death an infiltra¬ 
tion of the cellular tissue, of the thighs and quarters, with an'ap- 
pearance of gangrene, was manifested. The arachnoid membrane 
of the spinal cord in two subjects contained more serosity than 
usual; in one of them only its tint was doubtful. 
Lastly, the nerves of the spinal cord in neither of these car-
