ACADEMY OF GENOA. 



On the 26th of January last this academy had a public 

 meeting, which was attended by the chancellor of the ex- 

 chequer Le Brun, member of the French National Institute, 

 and other distinguished inhabitants. M. Cotardo Solari 

 opened the meeting with a discourse on the following sub- 

 ject : *' That learning, when not regulated by wisdom, is 

 productive of more injury than benefit to a state." The fol- 

 lowing prize questions were afterwards announced : 



1. Has any other of the heavenly bodies, besides the sun 

 and moon, any influence upon the meteorological appear- 

 ances of the world ? 



2. Which is the best method of rendering the harbour of 

 Genoa more secure and convenient for shipping ? 



3. Whether is it more advantageous for the inhabitants of 

 the Ligurian republic to encourage the wine or oil trade? and 

 what is the best method of cultivating the vine, and the plants 

 %vhich produce oil ? 



The prize for the best answer to each of these questions is 

 a gold medal of 400 ducats in value : the second best dis- 

 course will be rewarded with a silver medal. The discourses 

 ^nust be given in on or before the 1 3th of November next.
