    Since Refearch III. has been printed, I have endeavoured to afcertain the quantities of nitro- gene produced when nitrous oxide is refpired for a conliderable time. In one experiment, when I breathed about four quarts of gas in a glafs bell over impregnated water for near a minute, it wasdiminifhed to about two quarts; and the refiduum extinguiflied flame. Now the experiments in Refearch II. prove that when nitrous oxide is decompofcd by com- buflible bodies, the quantity of nitrogene evolved is rather greater in volume than the pre-exifting nitrous oxide. Hence much of the nitrogene taken into the fyflem during the refpiration of nitrous oxide, mufl be cither carried into new combinations, or given out by the capillary veflcls through the Ikin. It would be curious to afcertain w’hether the quantity of ammoniac in the faline matters held in folution by the ferreted fluids is increafed after the refpiration of nitrous oxide. Experiments made upon the confumption of nitrous oxide mingled with atmolpherie air
