Concerning Stones voided per Anum. By Mr. David Martineau, Surgeon at 



Norwich, N° 380, p. 433. 



These stones were voided by a poor woman per anum, on the 26th, 27th, 

 and 28th of March, 1723, being then pregnant about the llth or 12th week. 

 On the 23d, she seemed in the extremity of a convulsion fit, attended with 

 violent vomitings, which when over, she complained of great pain in her back, 

 from her reins downward to the anus. She continued with much pain the whole 

 day; and on the 24th, in the night, her fits returned with double force, her 

 pains also increasing like labour pains. Glysters were attempted, but none 

 could be thrown up, though repeated by some of the most experienced nurses; 

 on which Mr. M. gave her a gentle draught, which she observed increased her 

 pain with a strong tenesmus, that continued near 3 hours before the largest 

 stone appeared ; after some hours she voided 2 more stones ; and the next day, 

 at 4 hours distance, other 2. She recovered perfectly, and was delivered of a 

 very fine live girl, on the 24th of August following. She had been frequently 

 troubled, for 14 years past, with pains in her side and stomach, without 

 vomitings. 



The size of the stones, their seat and substance, are what seem wortliy of 

 speculation ; their being all alike in colour and weight, according to their 

 dimensions, is the reason Mr. M. broke but one.

In this and the following letter of Mr. Leuwenhoeck's there is nothing suffi- 

 ciently interesting for translation. In the concluding part of the second letter 

 Mr. L. gives an account of an experiment, in which, during an attack of what 

 he terms a palpitation of the diaphragm, he inspired air through a glass tube 

 filled to the height 3 transversorum digitorum with spirit of wine impregnated
