or such symptoms as denote a reflux of the matter pent up in the bone into the 

 mass of blood ; the operation then will afford very little hopes of success : whereas 

 the spina ventosa that affects the extremities of long bones only, and that which 

 appears in scrophulous cases in the bones of the carpus and tarsus, when the 

 discharge is not great, are best cured by lenient means, and the most pacific 

 methods. 



5. That in that stage of the spina ventosa, in which the bone is carnified, that 

 is, turned into flesh, with a painful fungus shooting out, as well from the callous 

 matter spread over the carious bone changed into flesh, as from the carious bone 

 itself degenerated, that in this case, as there can be no hopes of restoring it to 

 itself, the removal of the bone so degenerated, is the only method to be pursued; 

 as that will make way for the application of the actual cautery, in which the cure 

 principally consists: and if this does not succeed, we must proceed to amputation. 

 This was the case of Mr. Coreho in St. Mary Axe, whose thumb Mr. Sainthill 

 took, off the 26th of October, 1739: the last bone of which, afifected with a 

 spina ventosa about 18 years, was so swelled out, and changed into flesh, that 

 not the least part of this bone, as a bone, was found, but only its cartilaginous 

 covering, in the articulation with the second intemode; all the bone itself being 

 nothing else but a lump of flesh. 



Extract of a Letter from Mr. John Henry Winkler, Grtec. el Lat. Litt. Prof, 

 publ. Ordin. at Leipsic. Concerning the Ejects of Electricity on Himself 

 and his Wife. N°480, p. 211. 



When Mr. W. heard of Mr. Muschenbroek's experiment,* he tried the same; 

 but he found great convulsions by it in his body. It put his blood into great 

 agitation ; so that he was afraid of an ardent fever ; and was obliged to use re- 

 frigerating medicines. He felt a heaviness in his head, as if a stone was lying on 

 it. It gave him twice a bleeding at the nose. His wife, who had only received 

 the electrical flash twice, found herself so weak after it, that she could hardly 

 walk. A week after, she received only once the electrical flash ; a few minutes 

 after it she bled at the nose.
