26th she was thirsty and languid. The swelling was removed; the
quantity of urine discharged in the last twenty-four hours was about a
pint. She continued to mend from this time, and is now in good health.

A giddiness of the head, more or less remarkable at times, was
observed to follow the use of the Foxglove, and it lasted nine or ten
days.

This is the second time that I have relieved this patient by the
infusion of Foxglove. I used the same proportion of the fresh leaves
the first time as I did of the dried ones the last. The violent
vomiting which followed the use of the infusion made with the dried
leaves, did not take place with the fresh though she took near a pint
made with the same proportion of the herb fresh gathered.

REMARKS.

The above is a very instructive case, as it teaches us how small a
quantity of the infusion was necessary to effect every desirable
purpose. At first sight it may appear from the concluding paragraph,
that the green leaves ought to be preferred to the dried ones, as
being so much milder in their operation; but let it be noticed, that
the same quantity of infusion was prepared from the same weight of the
green as of the dried leaves, and consequently, as will appear
hereafter, the infusion with the dried leaves was five times the
strength of that before prepared from the green ones. We need not
wonder, therefore, that the effects of the former were so
disagreeable, when the dose was five times greater than it ought to
have been. But what makes this matter still more obvious, is the
mistake mentioned at first, of two tea spoonfuls only being given for
a dose. Now a tea spoonful, containing about a fourth or a fifth part
of the contents of a table spoon, the dose then given, was very nearly
the same as that which had before been taken of the infusion of the
green leaves, and it produced precisely the same effects for it
increased the urinary discharge, without exciting the violent
vomiting.

Letter from Doctor JOHNSTONE,
Physician, in Birmingham.

Dear SIR,

The following cases are selected from many others in which I have
given the Digitalis purpurea; and from repeated experience of its
efficacy after other diuretics have failed. I can recommend it as an
effectual, and when properly managed, a safe medicine.

I am, &c.
