AEROSTATION. 



HE attention of the public has been lately directed to 

 this art, almoft forgotten in England, by the arrival oi 

 M. Garnerin from Paris with two aeroltatic machines of 

 confiderabl-e fize, and a parachute, which have been exhi- 

 bited for fome time pair in the Pantheon. As this art, how- 

 ever little it may promife in other refpects, has been found 

 beneficial in military tactics, and might be employed with 

 great advantage in making meteorological and ftatical ex- 

 periments, it is well worth the notice of icien title- men : 

 we therefore hope that the following particulars refpecti'ng 

 M. Garnerm's two aerial excurfions in England, on the 28th 

 of June and 4th of July, will be gratifving to. our readers* 

 and particularly to thofe who had not an opportunity of feeing

 hiftorical view of the progrefs of aeroftation, with an engrav- 

 ing of M. Garnerin's balloons and his parachute.

 to promife weather urfiicfantiy favourable for the purpoie, 

 though it was rainy. At eleven o'clock, therefore, he begaa 

 the chemical operation;- neeeffarv for the production of the 

 inflammable gas. The balloon filled rapidly, though confi- 

 TdeAbly agitated by the wind. 



From one o'clock to halt pnft four, the wind continued to 



increafe, and at length blew fo violently, that,, had he made
