This work is important as containing the first account of the air-pump invented by OTTO v. GUERICKE, the author's 

 friend. 



'Reading in 1657, in Schott's Mechanica hydraulico-pneumatica, of Guericke's invention of exhausting the air in a closed 

 vessel, ROBERT BOYLE set Robert Hooke to contrive a method less clumsy, and the result was the so-called macnina 

 Boyleana, completed towards 1659, and presenting all the essential qualities of the modern air-pump.' Agnes M. Clerke.

 inventor of the Torricellian tube. 



It includes full accounts of the aerostatic experiments of ROBERT BOYLE and OTTO y. GUERICKE.

 Impoitant as giving the author's linal conclusion as to the presence of an atmosphere on Venus. ' It was founded, 

 first, on the rapid diminution of brilliancy towards the terminator, attributed to atmospheric absorption ; next, on the 

 extension beyond the semicircle of the horns of the crescent ; lastly, on the presence of a bluish gleam illuminating the 

 early hours of the Cytherean night with what was taken to be genuine twilight.' Agnes M. Clerke.

With dedication to George III. ' Schroter was the founder of descriptive astronomy in Germany, as Herschel was in 

 England . . . With instruments of gradually increasing power, he studied during 34 years the topography of the moon 

 and planets. The field was then almost untrodden . . . and he has since had no equal in the sustained and concentrated 

 patience of his hourly watchings . . . He laid the foundation of the comparative study of the moon's surface, and 

 the descriptive particulars of the planets laboriously collected by him constituted a sto:e of more or less reliable informa- 

 tion hardly added to during the ensuing half century.' Agnes M. Clerke,
