All that we as yet think ourselves authorised to assert is, 

 that the flattening of the earth cannot at any rate be greater 

 than l-300dth.

AEROSTATION. 



Garnci'iu^s 33d Ascent, 



vVN the 1st of July Garnerin, accompanied by Mrs. Gar- 

 ncrin, ascended in his balloon at Petersburgh in presence of 

 their imperial majesties, a great number of persons of di- 

 stinction, and an immense concourse of spectators. This 

 ascent, being Garnerin's 33d, took place in the garden of 

 the first corps of cadets, where a tent had been erected for 

 their majesties, who repaired thither at six o'clock in the 

 evening. After they had examined the balloon, Gan:ierin 

 presented to the emperor a small one filled with inflammable 

 air, which his majesty let off himself. Other balloons of 

 a similar kind were then presented to their majesties, and 

 to his royal highness the grand duke Constantine, who let 

 them off in like manner, in order to ascertain the direction 

 of the wind. The state of the atmosphere was exceedingly 

 favourable. At half after seven the aerial travellers entered 

 the car. The signal was given, and the balloon ascended in 

 a majestic manner. At eight o'clock it began to descend, 

 and the aeronauts reached the earth in safely on the little 

 Ochta at some distance from Petersburgh. 



Mr. Rolertson's Balloon. 



Mr. Robertson about the middle of .Tuly ascended in a 

 balloon at Hamburgh, accompanied by his friend M.Lliocrit. 

 The following are the details published by Mr. Robertson 

 himself: 



'' On the day on which I determined to make my ascent, 

 I resolved to rise to as great an elevation as my health and 

 strength would permit. M.Lhocst, my friend and com- 

 panion, having determined to accompany me, we took, 

 besides provisions, as large a quantity of ballast as the car 

 could convenientlv contain. After hovering some time ovtr 

 the city of Hamburgh, we resolved to ascend higher; and, 

 having tin-own out some ballast, we rose to such a height 

 that the elasticity of the air distended our balloon so much, 

 ihat wt yverc obliged to open the valve and suffer a certain 



quantity
