But his account of Caripe was fully corroborated by my host, who had gone there last year, and, by the help of the magnesium light, had penetrated farther into the cave than either the bishop or Humboldt.

Fortunately they were not delayed by lack of magnesium powder, a large quantity having been found in one of the laboratories.

He found that it contained small quantities of silica, iron phosphate, magnesium carbonate, calcium carbonate, calcium sulphate, potassium nitrate, potassium sulphate, sodium borate, sodium sulphate, and a considerable quantity of sodium chloride.

Magnesium flares and pistol lights were kept going almost without ceasing, while the artillery made a regular practice of loosing off a stated number of rounds per night.

Suitable febrifuges are found in potassium nitrate, potassium chlorate, sodium sulphate, or magnesium sulphate, either of which or a mixture of two or more of them, the animal will readily take in his drinking-water.
