M. Beyer of Paris has formed in his garden an apparatus 

 of this kind, which is very fimple, and at the fame time 

 can be infolatcd perfectly, effectual without any danger: It is a conductor 

 pk2e. at wn i ch can, alternately at pleafure be infolated, or not infolated, 



and made to aft either with a ball, or with a point. The 

 communications between it and the earth are well eflablifhed, 

 and as the obfervations can be made at more than an hundred 

 feet from the apparatus, there is not the Jeaft danger of any 

 accident.

Balloon projeft. The celebrated Aeronaut Robertfon, who afcended from 



bertfon, 13* feet Pcterfburg lafl, year, is endeavouring to obtain the neceflary 



diameter, afliflance at that place for the conftruclion of an air balloon 



me"" 7 U? 5 ° on a vei 7 Jar £ e fcale; he propofes that it (hall be 732 feet 



in diameter, which he calculates will carry up 37 ton, and 



which he fuppofes, therefore, will eafily fupport 50 people^ 



and all neceflary accommodations for them, 



andaveffel It is to have attached to it a veiTel furnifhed with marts, 



yn ails, c. ^ a jj s ^ anc j ever y th er article requifite for navigating the 



fea in cafe of accidents, and provided with a cabin for the 



aeronauts, properly fitted up, galley for cooking,(proper ftores 



and an internal for flowing proyifians, and feveral other conveniences. To 



parachute 1 , render the afcent more lafe, it is to take up another fmaller 



balloon within it, and a parachute, which will render the 



defcent perfectly gentle, if the outer balloon burfls. 



From its conftruciion it will be calculated to remain in the 

 air feveral weeks, in which time many experiments in natural 

 philofophy, and agronomical obfervations may be made : It 

 is alfo fuppofed, that geography may be confiderabiy improv- 

 ed by its means, as the aeronauts will be neither flopped in 

 their courfe by mountains or forefts ; and fome have even 

 thought, that with the afliflance of the trade winds, a voyage 

 round the earth might be made in it between the tropics. Its 

 coft, it is calculated, will be nearly equal to that of a ftiip of 

 the line.
