the lake above the level of the Dead Sea, which gives a con- 

 siderable but not extravagant amount of descent for the Jor- 

 dan. Schubert's expedition arrived in Jerusalem, on the 28th 

 March, and quitted the Holy City on the 15th April. During 

 this period, Dr Erdl made 31 barometrical and thermometrical 

 observations, on the first floor of the Latin Monastery of St 

 Salvator. These indicated a variation of only 2". 9 ; for the 

 greatest height was 3i0"'.5, and the smallest was 307'". 6. The 

 height of Jerusalem, as deduced from these observations, and 

 according to SteinheiFs calculation, is 2472.9 Parisian feet 

 (2634 English feet) above the level of the Mediterranean Sea, 

 which agrees perfectly with Russegger's determination, who 

 assigns a height of 2470 Parisian feet to St Salvator. The 

 highest summit of the Mount of Olives is, according to Erdl, 

 only 83 feet (88 English) higher than the Latin Monastery; 

 but the bed of the Kedron, at the tomb of Jehosaphat is 333 feet 

 (355 English) lower than St Salvator. Damascus lies nearly 

 2200 feet (2344 English), the pass of Lebanon at Dschebel 

 Makmel 7154 feet (7G24 English), and the grove of the cedars 

 of Lebanon, 5878 feet (6264 English) above the Sea—CFrom

Rej^rton the Geology of Newfoundland. By J. B. Jukes, Esq. 

 RA. & F.G.S.* 



In the present state of geological science, an observer com- 

 mencing an investigation of a country at a distance from those 

 which have been already described, is very much in the condi- 

 tion of one who begins the science afresh. The nomenclature 

 and classifications with which he has been familiar, have to be 

 discarded, or at all events held as of uncertain application to 

 the things he has now to examine ; and instead of tracing and
