ner Statements of the number of pas

and offensive gases which appear insep-
arabic from the use of steam.
Professor Ramsay believes that the par
ticular defect giving rise to color blind
ness lies, not in the eye itself, but in the

lie accordingly argues that in such per-
sons the brain is at fault, and thence
proceeds to the assumption that it may
be equally true that the inability to per-
ceive certain colors is not due to defect
in the instrument of sight by the eye,
but to the power of interpreting the i'm
prcssions conveyed TO the brain by the
optic nerve.
