 XXV. 345. 



A beam resting on a cun'ed surface, answering the pur- 

 pose of Guerike's manometer, which was a thin ball sup- 

 ported by a bent lever balance ; but perhaps no improve- 

 ment. 



Manometer. E. M. A. VI. 734. 

 Gerstner's air balance. Gren. IV. 172. 

 Kramp's manometer. Hind. Arch. III. 233. 



Like Caswell's, an open hemisphere, to be depressed to a 

 given mark, by weights put in a dish. 



•fSay's areometer, with Arnim's remarks. 



Gilb. II. 230. 

 Journ. Phys. LVI. 366. 



Berger brought portions of air from different heights in 

 well stopped bottles, and compared the quantities of mer- 

 cury that was forced into them. But the method does not 

 appear to be very accurate.

Variations of the Barometer in 

 general. 



*Beaieon the barometer. Ph. tr. 1665— G. I. 

 153, 163. 



Boyle on the barometer. Ph. tr. l665 — 6. I. 



181. 

 Halley. Ph. tr. 1686. XVI. 104. 



The mercury is commonly low in calm weather before 

 rain, higher in serene settled weather ; lowest in high 

 winds, even without rain ; highest in E. and N. E. winds ; 

 high in calm frosty weather : it rises fast after storms of 

 wind ; it varies most in high latitudes, within the tropics 

 very little. It has been observed by others, that N. and 

 N. E. winds are heavier than S. and S. W., as being colder. 



Lister on the barometer. Ph. tr. 1 684. XIV. 



790. 

 Leibnitz on the cause of the changes. A. P. 



1711. H. 3. 



Leibnitz invented a machine to illustrate the variations of 

 the barometer by the effects of the fall of a body upon the 

 equilibrium of a balance. 



Desaguliers on the variation of the barome- 

 ter. Ph. tr. 1717. XXX. 570.
