Further experiments of the Somali arrow poison by B. Haines, M. B., assistant surgeon (from Transactions of the Medical and Physical Society of Bombay. No. 2. new series 1853-1854.) "Having while at Ahmednuggur received from the secretary a small quantity of Somali arrow poison, alluded to by Mr. Vaughan in his notes on articles of the Materia Medica, and published in the last volume of the Society's Transactions, and called 'Wabie,' the following experiments were made with it:-- "September 17th. 1. A small healthy rabbit was taken, and the skin over the hip being divided, a piece of the poisonous extract about the size of a corn of wheat was inserted into the cellular tissue beneath: thirty minutes afterwards, seems disinclined to move, breathing quicker, passed * *: one hour, again passed * * * followed by * * *; has eaten a little: one hour and a half, appears quite to have recovered from his uneasiness, and has become as lively as before. (This rabbit was made use of three days afterwards for the third experiment.) "2. A full-grown rabbit. Some of the poison being dissolved in water a portion of the solution corresponding to about fifteen grains was injected into an opening in the peritoneum, so large a quantity being used, in consequence of the apparent absence of effect in the former case: five minutes, he appears to be in pain, squeaking occasionally; slight convulsive retractions of the head and neck begin to take place, passed a small quantity of * *: ten minutes, the spasms are becoming more frequent, but are neither violent nor prolonged, respiration scarcely perceptible; he now fell on his side: twelve minutes, several severe general convulsions came on, and at the end of another minute he was quite dead, the pulsation being for the last minute quite imperceptible. The chest was instantly opened, but there was no movement of the heart whatever. "September 20th. 3. The rabbit used for the first experiment was taken and an attempt was made to inject a little filtered solution into the jugular vein, which failed from the large size of the nozzle of the syringe; a good deal of blood was lost. A portion of the solution corresponding to about two grains and a half of the poison was then injected into a small opening made in the pleura. Nine minutes afterwards: symptoms precisely resembling those in number two began to appear. Fourteen minutes: convulsions more violent; fell on his side. Sixteen minutes, died.
