Father Lana was a friend of his fellow-Jesuit Kircher (q. v. ante), and though believing with most savants of his day- 

 in Perpetual Motion, was a genuine observer and experimenter. He Is also noteworthy as the first snggester of the> 

 Balloon ;see the next article), and his calculations regarding its practicability were checked and approved by Leibxiz. 



' The above work may be regarded as an attempt to explain various theories advanced in the Prodromo [v. infrn'^. The- 

 third volume, Avhich did not appear until the author's death [out of nine volumes intended by him], is said by his. 

 bibliographer Eyries to be 'tr^s-rare'. It would require an explanatory volume to give an idea of this work, which is 

 truly a cyclopaedia of all sciences connected with natural philosophy.'— Libri Catalogut. 



It describes a large number of 'perpetual motion' machines, while one chapter treats 'of motion which !•} called 

 electric attraction '.

Tliis work is of great importance in the history of ballooning as having been the first to formulate a theory of 

 aerostatics. The author proposed — besides many other curious experiments— to exha'.ist hollow globes of copper, which,. 

 being li},'hter than the air, were to raise the vehicle placed underneath. Plate II (No. 2421 ante) illustrates this idea,, 

 which, impracticable itself, nevertheless formed the basis of Montgolfier's invention.
