Footnote 42:

Formic acid is so named because it was originally obtained from the red ant (Formica rufa). It is now made from starch.

Footnote 44:

Nearly all the chloroform used in Great Britain and her colonies is made in Edinburgh, where the spirit duty is lower than in England. The London druggists have almost ceased to make it, as they find it cheaper to get it from the trade in Edinburgh.

Footnote 45:

The Edinburgh druggists suffered a great loss in 1850 from purifying their chloroform in this way on the recommendation of Dr. Gregory, who was not aware of the consequences, although they had been stated by Dumas (Ann. de Chim. et de Physique, t. lvi, p. 117).

Footnote 46:

I have seen some specimens of chloroform that left a white, limy-looking stain on the hand, which I believe was a minute quantity of crystalline chloride of carbon. These specimens were unobjectionable for all practical purposes, and had the merit of keeping remarkably well.

Footnote 50:

Since the above was written, I have met with an instance in which the pulse was only 40 in the minute, as the effects of the chloroform were subsiding. There was neither sickness nor loss of blood. The case was that of a gentleman in good general health, who inhaled chloroform whilst Mr. Brodhurst endeavoured to make forcible flexion of the femur on the pelvis. He woke without any unpleasant symptoms, and the pulse resumed its natural frequency.
