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 suggester of tha. 

 Balloon (see the next article), and his calculations regarding its practicability were checked and approved by LEIBNIZ:. 



' The above work may be regarded as an attempt to explain various theories advanced in the Prodromo [_v. infra\ The- 

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

 bibliographer Eyries to be 'tres-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 Catalogue. 



It describes a large number of 'perpetual motion' machines, while one chapter treats 'of motion which is called) 

 electric attraction '.

This 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 exhaust hollow globes of copper, which,, 

 being lighter 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.

'John Landen attacked this [Clarke's ' Dissertation on the Summation', etc.] in a pamphlet, on the ground that the* 

 method was contained in Simpson's ' Mathematical Dissertations'. Clarke replied in a 'Supplement' (1782), and to a 

 further attack in ' Additional Remarks ' (1783). The controversy is noticed in Button's Mathematical Dictionary.'

There was no copy of any edition of this rare work in the Libri Collection, nor was it known to Brunet, Graesse, or 

 Poggendorff. Professor de Morgan, who seemingly had never seen a copy of it, only refers to the author in his ' List of 

 loSO Names of Authors of Works on Arithmetic ' as Landus, nor is the work mentioned in Mr. R. Brown's ' Bibliography 

 of Book-Keeping.'
