Vid. Mr. White's useful treatise on the management of pregnant and
lying-in women, p. 279.

applications in the ulcerous sore throats, Essays medical and
experimental, Vol. I. 2d edit. p. 377.

[19] The author of these observations.

[20] Directions for impregnating water with fixed air, in order to
communicate to it the peculiar spirit and virtues of Pyrmont water, and
other mineral waters of a similar nature.

[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.
