peculiar and original degeneration in the juices? and whe- 

 ther these diseases of the juices arise wholly from a chauiie 

 in the vital functions of the vessels and solids, or depend 

 chiefly on them ? In case this question be answered in tlic 

 affirmative, Is the change of the juices which appears after 

 the use of medicines, to be deduced chiefly from the action 

 of these medicines on the juices and solids ?" 



The answers to these questions must be written in a 

 strange hand, and furnished with a motto. The name must 

 be written by the author himself in a sealed note. The 

 papers may be written in Dutch, German, but not in Ger- 

 man characters, English, Frencli, or Latin, and must be 

 transmitted, post paid, to the first secretaiT, professor 

 Rossyn, or to the assistant secretary. Dr. Van Toulon, at 

 Utrecht. They must remain the property of the society, 

 and can be printed only by them.

AEROSTATION. 



Bologna, October 8th. 



Yesterday the long announced aerial excursion of Count 

 Zambeccari took place, and in a manner entirely new. The 

 balloon, which was furnished with a lantern, and which 

 the count imagined he should be able to direct by means of 

 two wings applied to it, ascended in the night-time. Dr. 

 Grassetti and M. Andreoli accompanied the aeronaut in tlie 

 car. About one o'clock in the morning the balloon was 

 seen at Cartel -Franco, about twelve Italian miles from Bo- 



losrna.
