"The author is to be congratulated on producing a work that contains an
immense amount of information with a good bibliography on the subject. He
has given us an excellent general and unbiassed view of the facts and theories
of colour vision."-Nature

"The vast literature of colour vision consists almost entirely of papers written
in support of some particular theory. It is therefore with unusual pleasure
that we welcome this excellent all-round résumé of the subject....We can only
refer our readers to this storehouse of information. The bibliography provided
is excellent...and throughout Mr Parsons treats his subject with a scientific
feeling that is admirable."-The Lancet
