Notes. 
There are no laboratories for the professors of botany, geology, 
mineralogy, and comparative pathology. There is no botanical 
gallery, though there is a considerable botanical collection 
awaiting arrangement. There are no funds for utilising the land 
bought in the Bois de Vincennes for cultural experiments. 
There is no marine zoological station attached to the museum ; 
the galleries of palaeontology need improvements ; an additional 
assistant is required to classify the anthropoda, and another for 
the mollusca, &c. The anthropological gallery and library need 
enlargement. The library contains 100,000 volumes, and was 
built to receive only 30,000. 
According to “ Science,” the decrease of the forests in the 
Russian provinces of Moscow and Nishni-Novgorod has been 
attended by a deterioration of climate and a diminution of fer- 
tility. The Moscow Government used to be rich in fruit trees, 
but apples and cherries have now greatly fallen off in number, 
whilst pears have wholly disappeared. 
Herr Christiani (“ Verhandl. Physiol. Gesell. Berlin ”) has dis- 
covered in the brain the centre of co-ordination, — that is, a 
defined spot, the integrity of which is essential to the co-ordina- 
tion necessary for locomotion, and for the maintenance of equili- 
brium during sitting and standing. Its destruction involves 
immediate and permanent abolition of the normal use of the 
limbs. It is situate in front of the inspiratory centre of the third 
ventricle.
