iron, 4 feet long, and an inch and a quarter broad, having a polished brass bar 

 of the same length and width screwed to it before, with 4 steel screws, and being 

 also capped (b) with steel, and thereon a lever (c) moving on a stud of steel, 

 which communicates with another less lever (d) also on a stud, having a chain 

 (e) at the end of it, which laps round an axis (f), to which the index was fixed, 

 which shows the degrees marked on a semicircular arch (g) ; under the steel 

 screw-heads there are small slits in the brass bar, except the lowermost, which is 

 fixed, which admit of its expanding, by which it protrudes and operates on the 

 first-mentioned lever, which being raised moves the less lever, and so draws the 

 chain which turns the axis fixed to the index, which shows the degree of warmth 

 of the weather marked on the semicircular arch. At h is a screw through two 

 studs, to draw the great lever backward and forward, as occasion may be ; i is a 

 counter-balance to the small lever to draw the hand back when the brass bar 

 shrinks. 



To the above the editor adds the following note. 



In the beginning of the year 1735, I invented, and caused to be constructed, a thermometer on the 

 same principles as this : 1 found that a rod of brass 3 feet long was sensibly affected by the changes 

 of heat of the weather, having one exposed in my garden during the hard frost of the winter 1739 

 and 40. And my instrument was very sensible with either a brass rod or an iron rod, when the 

 bottom of it was placed in a sand-heat for chemical uses ; but I shall refer the reader to the appendix 

 to the preceding number, where I have given a full description of my invention, and the reasons why 

 I did not publish it before; though I have shown the instrument to scores of people ever since May 

 1735, and sent a description and draught of it to M. BufFon, superintendant of the Royal Physic 

 Garden at Paris in the year 1744., in order for his laying it before the Royal Academy of Sciences at 

 Paris, from which I had some time before received a diploma on having the honour of being ap- 

 pointed one of their corresponding members. C. M. — Orig. 



j4n Abstract of the Remarkable Case and Cure of a Woman, from whom a Fetm 

 was extracted, that had been lodged 13 Years in one of the Fallopian Tubes. 

 By Dr. J. Mounsey,* Physician to the Army of the C%arina.\ N° 486, 

 p. 131. 



A soldier's wife, of Abo in Finland, who had been the mother of 2 children, 

 being pregnant a third time in the year 1730, was afflicted with violent pains 



* After his return from abroad Dr. Mounsey was elected physician to Chelsea Hospital. This situ- 

 ation he enjoyed for a number of years, to the great disappointment of several other physicians, to 

 whom the reversion of that place had been promised. Dr. M. was a very eccentric character ; and 

 although the few written documents, which he has left on medical or other subjects, possess no re- 

 markable excellence ; yet we are told that in his conversation he discovered great strength of under- 

 standing, joined to an exquisite degree of humour. He died in Deer. 1788, at the advanced age of 96. 

 In the morning on which he died, he said to his attendant, " I shall certainly lose the game." Being 

 asked what game ? he replied, "The game of 100, which I have played for very earnestly many 

 years; but 1 shall now lose it, for I expect to die in a few hours :" and his prediction proved true.
