EDITORIAL NOTES AND COMMENTS
The symptoms of cocain poisoning usually appear quite promptly. They are ushered in by a period of nervousness and excitation, sometimes almost of hysteria. Respiration is rapid and deeper than normal, and the pulse is markedly accelerated. The throat is dry, and the patient may complain of a choking sensation. The pupils are dilated, owing possibly to direct action on the muscular fibers of the iris.
