Cabrolias Observ. 28, at the latter end of his Alphabetum Anatomicum, 

 notices a kidney he found imposthumated in a dead body, which weighed 14 lb. 

 occasioning symptoms that were supposed by several of the medical persons 

 who were consulted, to proceed from a stone. 



Account of a Stone of the Bladder, ivhich iveighed 5 1 Ounces, and a Stone out of 

 the Bladder ivhich adhered to it. By Dr. Charles Preston. N° '22'2, p. 310. 

 In the Hospital of Charity at Paris, is preserved, among a great number of 

 stones extracted from the bladder by the operation of lithotomy, one of a 

 prodigious size, weighing about 51 oz. or 3 lb. 3 oz. ; it was taken from one of 

 the religious brothers in the house, who attends the sick, in the month of June, 

 l6gO; but he died in the operation ; for the stone being so large, it could not 

 be extracted till after his death. It is kept as a great curiosity. 



In the month of June, 1696, while I was at Ghent attending his majesty's 

 hospital, a very singular case happened in the operation of lithotomy, viz. a 

 stone adherent to the bottom of the bladder : this was found by M. Parfaim, 

 lithotomist of the place, who, when he made the operation, could not extract 

 the stone, but was obliged to leave his patient in that case : there ensued an 

 imposthume, so that 8 days after lie extracted it with great ease. The next 

 day he showed me the stone, to which the fibres by which it was tied were yet 

 attached, and could be easily observed by the naked eye, without the help of a 

 microscope ; so that I could not question any thing as to the matter of fact. 

 All those that I had occasion to converse with of lithotomy, while at Paris, deny 

 that the stone is adherent to the bottom of the bladder, and that they never 

 observed the same ; and I do not remember of any author that writes of it, so 

 that it seems to be a case altogether new. 



Effects of a very extraordinary Thunder near Aberdeen in Scotland. In a Letter 

 to Dr. Geo. Garden. N° 222, p. 311. 

 This happened July 24, l6y5. The day was clear and pleasant, till about half 

 past 3 afternoon; when some rain fell ; then two claps of thunder, rather mode- 

 rate ; then fell a heavy shower of hail, accompanied with a third clap of thun- 

 der, very tremendous, attended with great damage to the houses and people. 

 In a school were the master and 15 boys; the building was perforated and shat- 

 tered in several places, illuminated as with a strong and sudden fire, attended 

 with a suffocating and sulphureous smell and dark smoke. The persons were 

 all either struck down, or badly wounded and bruised. Four were killed out- 

 right, the rest recovered in due time. In the parts where they were struck, 

 which was cluePiy about the shoulders, the fiesh was much discoloured, and the 

 clothes there cut or perforated, to appearance as if eaten by rats.
