series, A new, but this time a true, system of phrenology will be 
founded upon them; by this, however, I do not mean that it will 
be possible to tell a man’s faculties by the configuration of his 
skull, but that the various mental faculties will be assigned to defi- 
nite territories of the brain, as Gall and Spurzheim long ago main- 
tained, although their geography of the brain was erroneous.—

Dr. Brown Sequard has called in question the conclusions given 
above in lectures delivered in Boston last March. 
Rate or Growrn mm Man.—In an interesting account of the 
life and works of -the late Belgian anthropologist and statistician, 
Adolphe Quetelet, published in-‘*La Revue Scientifique,” occur 
the following remarks on the rate of growth in man. “The most 
rapid growth takes place immediately after birth; the infant in 
the space of a year grows about two decimetres.* The increase 
in size diminishes gradually as its age. increases, up towards the 
age of four or five years; when about three it attains half the 
size which it is to become when full-grown. When from four to 
five years of age the increase in size is very regular each year up 
to sixteen years, that is to say up to the age of puberty; this 
` annual increase is nearly fifty-six millimetres. After the age of 
puberty the size continues to increase, but feebly ; when from six- 
teen to seventeen years old the individual increases four centi- 
metres (+60 inch). In the two years following, it increases only 
One inch. The total increase in size of man dies not appear to 
be entirely terminated when he is twenty-five years old. The 
mean size is a little larger in cities than in the country.”

EW Rorarine Mrcroscore.— Mr. Browning has introduced 
into Cae the continental fashion of attaching the bar of the 
microscope to the stage which is made to revolve carrying the 
body with it. This, of course, gives a rotating stage without any 
difficulty in regard to centring. Any tremor, also, connected 
With oe revolving apparatus is common to the object and the 
ifying apparatus, and is therefore of little consequence. 
For objects illuminated from below, this arrangement is prac-
