the same month, when, finding no material alteration for the better, he ordered 

 her a brownish mixture, of which she was to take four spoonfuls every 4 hours ; 

 which, he informed Mr. G. was a decoction of the bark ; and said, on taking 

 this, she was better, as the mortification seemed inclined to stop. But as it was 

 a bad case, he advised the woman to be carried to an hospital : and in this con- 

 dition was she brought in, when she was immediately put into a course of the 

 bark, taking 1 dr. of the powder every 4 hours ; and in 48 hours taking it there 

 was a perfect separation of all the mortified parts. She was then ordered to take 

 it only 3 times in 24 hours ; and pursuing this method for 8 days, there was 

 a very good digestion from the parts above the mortification. The mortified 

 part became now so offensive, that the poor woman pressed him much to take oft' 

 her hands, assuring him she would go through the operations with good courage, 

 being very desirous to live, though in this miserable condition. 



July the 24th he took oft' both her hands : he had very little more to do 

 than saw the bones, nature having stopped the bleeding, wJien she stopped the 

 mortification. In a day or two after, he took oft' all the toes from both feet, 

 and now discontinued the bark, the parts appearing in a healing condition ; 

 which went on so for 5 weeks, when, on a sudden, the parts began to look 

 livid, her stomach failed her, and she was feverish ; but, on taking 1 oz. of the 

 bark, in 36 hours her sores began again to look well. She was not suff'ered to 

 leave off" the bark so soon this time, but continued taking it twice a day for a 

 month. She was then almost well : that part of her face from which the nose 

 mortified, was healed in 7 weeks ; the stumps of both arms were entirely healed; 

 and both feet were well, only waiting for 1 piece of bone scaling oft', wliich he 

 believed would be in a very short time ; and she was then in good health.

In this letter Dr. P. states that he had communicated to Dr. Birch Dr. 

 Whytt's postscript to his observations on Lord Walpole's case, with some reflec- 

 tions on Dr. Springfield's account of the lithontriptic quality of the Carlsbad 

 mineral waters : also an instance of the efficacy of electricity in the cure of a 

 palsy by Mr. Br}done. 



Postscript to Dr. WhytCs Observations on Lord /Falpole's Case. 



Making some experiments with diff'erent calculi, there was one almost as white 

 as chalk, but less hard than the others ; and which was not in the least degree 

 dissolved or softened by being infused 20 days in oystershell lime-water, but 

 yielded somewhat to a solution of Spanish soap in common water. From this 

 experiment it may be concluded, that it is better to prescribe both soap and lime 

 water for the stone, than either of them alone ; and that if one of these reme-
