The high temperature of Trieste agrees well with its bare and burnt 

 surroundings. In Croatia, far from the sea and where there are woods 

 in the jilain, it is cooler, warmer again in the Hungarian prairies, but 

 50 or i)° cooler in southern Hungary and Banat, where the vegetation is 



luxuriant.

Poti is in the midst of the swamps and forests of Mingrelia and its 

 temperature is 4° lower than in the Dalmatian towns on the Adriatic. 

 Even Kutais is cooler than Eagusa, though the former lies far in the in- 

 terior and the forests have been cut freely in its vicinity.

The low temperature of Lenkoran is especially noteworthy because it 

 is deep in the interior of a continent and the cloudiness and rainfall 

 are light. Yet in the vicinity are extended forests Avith luxuriant 

 vegetation. It is on the Black Sea, while Poti is on the Caspian. Near 

 l)oth are extensive forests. If the July temperature is reduced to 42'^ N. 

 but not corrected for elevation it proves to be 73°.6, only 0^.4 higher 

 than that of Poti. 



Dr. Woeikoff also calls attention to ih^ remarkable relations of 

 Bosnia, Herzegovina, and Dalmatia, along latitude 44° N. The tem- 

 peratures are here the animal means.
