The thoracic cavity of a dog which died in 10 minutes after the injection of 14 grains of the poison, contained acetate of morphia, as did also the small intestine of a cat, and the duodenum of a dog-, after the poison had been injected into those parts. Thirty-six grains of acetate of morphia were injected into the crural vein of a dog, and 30 grains into the jugular vein of a horse, but none could be detected in the blood, drawn li hour after injection from the opposite vein; but on repeating the experiment, and bleeding the animal in 10 minutes after the poison was injected, it was found in the blood. M. Lassaigue concludes from his experiments, 1. That in many cases of poisoning by acetate of morphia, sensible traces of that vegetable poison may be chemically detected. 2. It is alvvajs found in the viscera in which it was first deposited. o. The contents of the stomach, ejected by vomiting soon after the injection of the poison into it, contain ponderable quantities of the acetate of morphia. 4. All attempts to detect its presence in the blood of animals poisoned by acetate of morphia, have been ineffectual.--(Journ. de Pharmacie.). 2. Cause of the Odour of Hydrogen Gas. In our last number we quoted some observations by Berzelius respecting the oil which communicates to hydrogen gas, its peculiar odour: as the circumstance, although well known to chemists, has been seldom adverted to, we shall lay before our readers a brief account of some facts which had been previously ascertained respecting it..About the year 1800, Proust stated, in a memoir read before the National Institute, that this peculiar odour resides in a volatile aromatic oil, of a bituminous flavour, which is held in solution by the gas; and in support of his opinion, lie add...
