V. Mont Venfoiix. 



This mountain is remarkable for the suddenness of its eleva- 

 tion above the surrounding country. It is of limestone ; and its 

 height, as determined by I3aron von Zach, is 985-i- French toises, 

 or tiSOl English feet, above the level of the sea. It is certainly, 

 therefore, one of the highest limestone mountains which are 

 known to exist. The usual calcareous petrefactions abound on 

 the south side of it ; but it is said that none are to be found on 

 the north side. If this be true, it is a very remarkable pheno- 

 menon indeed, and seems hardly susceptible of explanation, 

 unless the petrefactions be confined to the surface of the rock. 

 In that case we are at liberty to suppose that there was a time 

 when the sea washed its south side, while the north side must 

 be supposed to have been always screened from the action of 

 that element. The mountain is covered with angular fragments 

 of a very compact limestone. 



Petrarch was partly educated at the foot of this mountain at 

 Carpentras. He ascended it in 1345 with his brother Gerard, 

 and on his return wrote a spirited account of his expedition in a 

 letter to his friend John Colonna, which is to be found among his 

 Epistote de Rebus Familiaribus. The latitude and longitude of 

 this mountain as determined by Baron von Zach is as follows : 



Latitude 44° 10' 27-6" N. 



Longitude .... 22 56 34-4 E. from Ferro.

VI. Positio)is of various Places in the Coast of the Adriatic Sea. 

 Baron von Zach gives the following geographical positions of 

 various places on the coast of the Adriatic Sea. He gives them, 

 he says, v.ith some reserve, and only provisionally. They have 

 been determined by two Neapolitan astronomers, and doubtless 

 from the best data which they could procure ; but it does not 

 appear that these astronomers determined any of the positions 



by observations of their own.
