This disease is known to physicians by the name of coma somnolentum, in which the patient complains of a constant drowsiness. The patient often falls asleep at meals, in conversation, and in the midst of business, and when he is awaked he soon falls asleep again. It is not attended with any fever.

There arc two kinds; the one is serous or watry, and the other sanguine. The first requires the serous evacuations to be restored or promoted. Sneezing powders are of great use, be-cause they discharge the serum through the nose, and stimulate. When there is a load of viscid phlegm on the stomach, give two grains of emetic tartar, with an ounce of manna, dissolved in water gruel, and this will carry it off upwards and downwards.

In the sanguine kind, when the blood circulates slowly thro the head, or Magnates there, as in those that are hypochondriac or scorbutic, all hot spirituous remedies are as bad as poison; but bleeding, clysters, gentle laxatives, cooling and nervous powders are useful. A red face, and eyes turgid with blood, show that bleeding is necessary.

Warm baths are bad in sleepy disorders, as well as saffron and opiates. Volatile spirits and salts are good in the cold se-rous kind, but not in the sanguine. Sneezing powders should not be used in the beginning of this disease if the body is full of blood, because they cause the humours to flow to the head, which may occasion an apoplexy.
