The Case of a Clergyman's Lady, at Cottered near Baldock, Herts, who had a 

 Stone under her Tongue. By JVm. Freeman, Esq. F.R.S. N° 401, p. 5. 



This substance, seemingly a concretion of stone or chalk, was voided in July 

 1748, from under the root of her tongue, just on the left side of the middle 

 string among the blood-vessels. It was lodged in a cell formed by itself, the 

 traces being left behind exactly answering. It was voided without pain, or effu- 

 sion of blood. 



The patient began to feel in the part afi'ected some uneasiness about 18 months 

 before the discharge. The pain extended itself sometimes along the jaw almost 

 to the ear ; the glands being at times swelled, and a salt rheum flowing into the 

 mouth. The swelling of the part gradually increased to about the size of a large 

 nutmeg ; and felt hard to the finger. 



About a fortnight before the discharge, some white specks appeared ; on which 

 it was supposed that matter was gathering ; and being still hard, a common 

 poultice of white bread and milk was applied ; after which it presently dislodged 

 itself, without any application, and left the patient ever since free from complaint. 



On Glasses of a New Contrivance, for preserving Pieces of Anatomy or Natural 

 History in Spirituous Liquors. By Claud. Nic. le Cat, M. D., F. R. S. &c. 

 Translated from the French by T. S., M.D., F.R.S. N° 491, p. 6. 



Having, in 1739, begun to make a collection of preparations in anatomy and 

 natural history, M. le Cat soon felt the necessity of contriving some kind of 

 vessel, or some way of closing the common glasses, which might prevent, or at 

 least diminish the quantity of spirituous liquor lost by evaporation. 



After trying several methods, he fixed on the glass, which is represented in 

 figures 10, and 11, pi. 10. Its difference from the common glasses consists in 

 having, quite round the edge of its orifice, a circular groove or channel, aa, 

 fig. 11, an inch deep for the smaller sizes, and 2 inches for the larger. This 

 circular groove is intended to receive a border, bb, of the same figure on the 

 cover c : in the middle of the concavity of this cover is a double hook, on which 

 the threads are to be fastened, which suspend the piece or preparation to be put 

 into the glass. 



In putting the piece into the glass, which contains the preserving liquor, care 

 must be taken to place it on the hooks in the same position, which you intend
