The Relative Weight of the Brain of Regulus satrapa and 
Spizella domestica compared to that of Man.—In the no- 
tices given by different writers on the relative weight of the brain 
to that of the body in different animals man has been given the 
foremost position. Thus, Landois* says the elephant has aéso- 
/utely the heaviest brain, but man has relatively the heaviest brain. 
Surely this writer must have overlooked the little golden-crested 
taken in their native habitat last summer, were weighed with a 
view of comparison, with these results: 
Body. Brain, 
Golden-crested kinglet ( Regulus satrapa)... ess... 974 4 
Chipping sparrow (Spizella domestica)......seseeesseseen 1734 og 
Designated in grains. 
As generally stated, man’s brain weighs 4} of that of the whole 
‘body. So far as the above figures show, the comparison bears 
out the following: the kinglet’s brain weighs 3}, the sparrow’s 
brain yy, or nearer 7, of that of the entire body respectively, 
the kinglet consequently having relatively the heaviest brain:—

Zoological News. Protozoa.—Dr. A. C. Stokes, of Trenton, 
N. J., describes eleven new species of American fresh-water 
Infusoria in the February number of the Journal of the Royal 
Microscopical Society, illustrating the same with a plate. Dr. 
okes thinks that identical species of Infusoria are not often 
found in the fresh waters of both the Old and the New Worlds, 
in which he will not receive the unanimous support of other 
workers in the same field.
