SIR,

ABOUT three weeks ago I put into your hands an extract of a letter,

I had then received from Dr. Whytt, containing a postscript to his

_Observations on Lord_ Walpole’_s Case_; and slightly mentioning some

doubts he had then about the justness of Dr. Springsfeld’s experiments

with lime-water, from some trials he himself had made, upon reading

that gentleman’s curious treatise on the extraordinary lithontriptic

quality of the waters at Carlsbad in Bohemia. Within these few Days,

Dr. Whytt having favoured me with a full account of those experiments,

I have herewith sent you his paper, in order, if you please, to lay

it before the Society; which the author desires may be done, in case

these observations should be judged useful.

The other paper inclosed was sent me by the same hand, to be likewise

presented to the Society, as a well-attested instance of the electrical

power in the cure of a palsy. To the other testimonies I have subjoined

what Dr. Whytt says in his letter to me, by way of strengthening the

evidence. I shall only add, that since Mr. Brydone, the author of

this account, has omitted telling how long the patient has continued

in perfect health since the operation, it appears she must have been

well for some months before the date of his paper; because, before the

end of last summer, Dr. Whytt transmitted the same case to me, which

I then returned, in order to have it drawn up in a fuller manner, and

with other vouchers besides the gentleman, who performed the cure. The

Doctor has been so good as to comply with my request, having procured

a more ample account of the circumstances from Mr. Brydone, and the

attestation of two ministers, besides that of the patient herself.[200]

My difficulties being thus removed, I believe I may now with freedom

offer this very curious case to the attention of the Society.
