' Its value as a work of reference was at once recognised. Its clear statement of facts and lucid reasoning closed a long 

 controversy, and proved the physical structure of the Weald to be the result of subaerial denudation in other words, due 

 to the action of rain and rivers. 1 Prof. Brniney, pr., F.R.S.

'II parvint cornme Torricelli a former des microscopes d'une grande puissance, qu'il executait lui-meme au moyen de 

 petits globes de verre. A 1'aide de ses microscopes il se proposa d'etudier le mouvement insensible des parties constitu- 

 antes des corps organises, le chyle, le Bel, les fibres, les muscles, le cerveau, et surtout le sang, dont les elements selon lui 

 consistaient en une multitude de petits anneaux roulant les uns sur les autres.' Biogr. Gen. 



The first two plates illustrate the microscope and accessory parts. Among the microscopic objects illustrated are 

 podura scales and the blo<xl.

His de Motu Gravium contains important observations on liquids discharged through orifices in the bottom of vessels, 

 which made him ' the founder of the theory of hydrodynamics ' (E. Much). The first treatise gives the author's quadrature 

 of the logarithmic spiral, while his de Motu Projectorum contains important ballistic investigations.

' His great discovery was the interpretation of the previously known fact that water will rise in a suction pump only to 

 the height of about 32 feet the idea that the column of fluid is sustained by the pressure of the atmosphere on the open 

 surface of fluid. The vacuum in the barometer is the Torricellian vacuum; and the barometer is sometimes called the 

 Torricellian tube. Torricelli also effected the quadrature of the cycloid in this he was anticipated by Roberval and 

 made other mathematical discoveries. To him is due the fundamental principle of Hydromechanics ; and he made and 

 greatly improved both telescopes and microscopes.'
