On the further success of the Blood-staunching Liquor. By a Surgeon of his 



Majesty s Fleet. N°97, p. 6ll5. 



Sir — I doubt not but you have heard, with what admirable success the royal 

 styptic liquor was used in the last engagement against the Dutch, by the 

 chirurgeons of the Earl of Ossory, Sir Edward Spragg, and Sir John Berry, and 

 others. A very good physician in Yarmouth, several credible persons also in 

 London and other places, some of whom have taken it inwardly themselves, 

 give the like commendation of it for stopping bleeding upon eruption or aper- 

 tion of a vessel in the lungs, or other internal parts, being administered accord- 

 ing to the printed direction. 



The Figures of some of Mr. LeewenhoelC s Microscopical Observations, formerly 

 published in N° 94, p. 66, with their Explication. N° 97, p. Q\\6. 



In fig. 7, pi. 2, AB is the great sting, or rather the sheath or case of the 

 hee,^ out of which were taken the two stings which he formerly noticed ; E is 

 the cavity of the sheath, in which the two stings, by and by to be described, 

 lie ; like a quill pulled out of a fowl's wing, and of that cut off a third part in 

 length, and by its sides bent a little inwards towards E. D is the thickness of 

 the case beneath: and about DA the two stings show themselves, each in a 

 place by itself. 



In fig. 8, HI is part of the sting taken out of the sheath AB, which appears 

 a little sideways ; whence it is, that the crooks or barbs KK do not show so 

 large nor sharp, as indeed they are. L is the back of the sting without barbs ; 

 which side or back is almost as broad as one of the sides of the sting, when the 

 barbs appear. 



In fig. 9, MN is the whole sting, taken also out of the sheath AB in fig. 7, 

 and with its back, which is without barbs (as has been shown in fig. 8, by L,) 

 turned to the eye. Here the barbs show themselves, though turned from the 

 eye, through the sting, as appears by R. The upper part of the sting NQ is 

 closed round about, and hollow within ; and the lower part QS is open. SM 

 is a part of the broken sinew, which is very near as long as the whole sting ;
