English we use different terms when speaking of the darkness of 
night and the black of a dress; or of the blonde hair and the 
yellowish-white corresponding color of other objects striking our 
eye-sight. The occasional existence of more than one term for 
one color for the reason just alluded to is observed in the languages 
of every portion of the globe. Curiously enough the ved color 
is not often diversified into different shades in the languages con- 
sidered ; in Spanish it is colorado, “ showing color;” this evidently 
means that red is the color striking our eye with the greatest in- 
tensity. 
7. Reduplication of the radix is very often met with in color 
names, but the cause of this is not always the same. In Klamath 
and the Sahaptin dialects it is distribution and repetition, in Da- 
kota it is the idea of intensity that has sedate this synthetic 
feature. 
` We think the inquiry into the color-sense and that into the 
color-blindness among the individuals of a people must be kept 
distinct from each other. It is premature to assume that a whole 
people can be color-blind, though its color nomenclature may 
largely differ from ours, but it is by no means improbable that 
color-blindness is more frequent among hunting and nomadic 
nations than among individuals of civilized races. This question 
can be decided by direct experimental observation only, while in 
the inquiry concerning color-sense, the science of linguistics is 
entitled to take part in the discussion.

THE HABITS OF A TARANTULA. 
BY MRS. MARY TREAT. 
E the past year I have been observing a large burrow- 
ing spider belonging to the family of Lycosidæ. Its habits 
and probably the creature itself, had entirely escaped the atten- 
tion of naturalists until recently. Its habitat is in Southern New 
Jersey. In the grove which’ surrounds the house where my 
_ observations were made, are many burrowing spiders which build 
open tubes lined with a web of silk, and a projecting rim of sticks 
and leaves are firmly held together with web to keep the sand 
and debris from falling into the nest. 
_ Last summer (1878), I accidentally found a covered tuha, per- 
fectly concealed, which aroused my curiosity subicien ty to keep
