Experiments and Observations on Different Kinds of Air Part 20

[21] Referring to the case communicated by Mr. Hey.

[22] He languished about a week, and then died.

[23] The vegetables which are most efficacious in the cure of the scurvy, possess some degree of a stimulating power.

[24] This refers, to an experiment mentioned in the first publication of these papers in the Philosophical Transactions, but omitted in this volume.

[25] The first account of this curious process was, I believe, given in the Mem. de l'Ac. de Sc. de Paris for 1742. Though seemingly less volatile than the vitriolic ether, it boils with a much smaller degree of heat. One day last summer, it boiled in the coolest room of my house; as it gave me notice by the explosion attending its driving out the cork. To save the bottle, and to prevent the total loss of the liquor by evaporation, I found myself obliged instantly to carry it down to my cellar.
