EXPERIMENTAL PROOFS

OF THE PROPERTIES OF HEAVY CARBONATEDHIDROGEN GAS.

THE properties of this gas being similar to those of the otherhidro-carbonates, it is unnecessary to exhibit experimental proofsof them ; those already advanced under the head of light carbo-nated-hidrogen gas, will explain them all with the exception ofits characteristic property of producing oil with oxigenated mu-riatic acid gas which shall be inserted here with a few otherinteresting remarks.

Experiment I.

Production of oil ly the mixture of heavy carlonated hidrogengas , with oxigenated muriatic acid gas.

Take a glass tube, send up into it three parts of fresh pre-pared heavy carbonated hidrogen gas, and add to it graduallyfour parts of fresh prepared oxigenated muriatic acid gas. Aftereach addition of the gas, shake the mixture; an absorption willtake place, caloric will be liberated, and the tube will becomefilled with white vapours. When the gases have totally disap-peared an oil of a pearl grey colour will be deposited.

This oil is heavier than water, its odour is agreeable andpenetrating, its taste is rather sweet. It becomes yellow by ex-posure to air.
