 The slighter effects of arsenic are said to have been repeatedly observed of late in this country from inhaling the products of the combustion of arsenicated candles,—an article of recent invention, in which arsenic, to the extent of three or four grains and a half in each candle, is introduced for the purpose of hardening the stearine chiefly used in manufacturing them. It is unnecessary to say, that such candles are prejudicial and ought to be prohibited. In a set of experiments made to try their effects by Messrs. Everitt, Bird, and Phillips in 1838, birds were killed in no long time, and small quadrupeds were severely affected, when kept in an apartment lighted with them.

Analogous to the effects of inhaling oxide of arsenic are those lately observed from the incautious inhalation of arseniuretted-hydrogen gas. Gehlen the chemist died of this accident, but no particular account has been published of the symptoms he suffered. Two cases, however, have been detailed within a few years. In one of these, which has been related by Dr. Schlinder, of Greifensberg, the individual inhaled in forty minutes about half a cubic inch of the gas, which is equivalent to about an eighth of a grain of arsenic. In three hours he became affected with giddiness, and soon afterwards with an uneasy sense of pressure in the region of the kidney, passing gradually into acute pain there and upwards along the back. General shivering ensued, with coldness of the extremities, and gouty-like pains in the knees, shoulders, and elbows. The hands and lower half of the fore-arms, the feet and legs nearly to the knees, the nose and region of the eyebrows, felt as if quite dead, but without any diminution of muscular power. There was also acute pain in the stomach and belly generally, painful eructation of gas, and occasional vomiting of bitter, greenish-yellow mucus. The most tormenting symptom, however, was the pain in the kidneys, which soon became attended with constant desire to pass water, and the discharge of deep reddish-brown urine, mixed with clots of blood. The whole expression of the countenance was altered, the skin becoming dark brown, and the eyeballs sunk, yellow, and surrounded by a broad livid ring. Warm drink brought out a copious sweat and removed the sense of numbness; but next day there was little change otherwise in the symptoms, except that the urine was no longer mixed with clots, and that the hair on the benumbed parts had become white. On the third day the pains had abated, and the urine became clear; but there was hiccup, an excited state of the mind, and a feeling as if a great stone lay in the lower belly. In seven days he was much better. In the third week the whole glans and prepuce became covered with little pustules which were followed by small ulcers. It was not till the close of the seventh week that he recovered completely. Dr. O'Reilly has related the following case, which arose from the inhalation of hydrogen gas impregnated with arseniuretted-hydrogen in consequence of the sulphuric acid used
