or what comes to the same thing, I0.8 Fall, for 101.2 English 

 feet. If we take the case of the observatory as the starting 

 point for the temperature where it is at 53°.06 Fah., 21°.24 Fah. 

 will then be given as the augmentation for 1222.5 English 

 feet, which corresponds to 103.348 English feet for each centi- 

 grade degree. 



6. Effects of Clearing a Country. — As new facts proving the 

 influence of clearing a country, in lowering the temperature and 

 diminishing the streams of water, M. Devize de Chabriol com- 

 municated to the Academy of Sciences a notice, in which he 

 established that, according to old charters of the 13th and 14th 

 centuries, the slope of the hill of Saint Flour was at that time 

 under vine cultivation ; he adds that now-a-days its cultivation 

 no longer proceeds. The chestnut, also, has now disappeared 

 from many districts in which it formerly flourished. Hence 

 numbers of villages which were situated near the summit of the 

 mountains have been abandoned, and many old springs have 

 also dried up. 



7. Fossil Bones of Sansan. — In Vol. xxii. p. 403 of this Jour- 

 nal, we inserted a notice regarding the fossil bones of the tertiary 

 formation of Simorre, Sansan, &c. More recently a large col- 

 lection of the organic remains of the Sansan deposit has been 

 sent to Paris by M. Lartet ; and, from the report made on the 

 subject to the Academy of Sciences by M. de Blainville, we now 

 extract the following summary of the animals hitherto found at 

 this highly interesting locality. Class Mammalia — Monkeys 

 belonging to a group analogous to the Gibbons, but not identi- 

 cal with the true Gibbons : of the insectivorous carnivora the 

 genus Talpa ; of the plantigrade carnivora the genus Ursus and 

 another genus resembling/it ; of the digitigrade carnivora the 

 genera Felis, Viverra, and a new genus Amphicyon ; there is 

 one fragment of a lower jaw which seems to indicate an animal 

 of the Seal family ; of the terrestrial edentata, a genus allied to 

 the Oryctcropus ; of the order Glires, the genera Myoxus and 

 Lepus ; of the elephants the genus Mastodon ; of the laman- 

 tines, the genus Dinotherium ; of the pachydermata, the genera 

 Rhinoceros, Pahcotherium, Equus, Sus, and Anoplotherium ; 

 of the ruminantia, the genera Cervus and Antilope. Class Avcs 

 —Two species of a genus not yet determined. Class Reptilia
