the same direction, and the cerebellar chamber projects considerably
beyond the cerebral.

When the gravest errors respecting points so easily settled as this
question respecting the posterior lobes can be authoritatively
propounded, it is no wonder that matters of observation, of no very
complex character, but still requiring a certain amount of care, should
have fared worse. Any one who cannot see the posterior lobe in an
ape's brain is not likely to give a very valuable opinion respecting
the posterior cornu or the hippocampus minor. If a man cannot see a
church, it is preposterous to take his opinion about its altar-piece or
painted window--so that I do not feel bound to enter upon any
discussion of these points, but content myself with assuring the reader
that the posterior cornu and the hippocampus minor, have now been
seen--usually, at least as well developed as in man, and often
better--not only in the Chimpanzee, the Orang, and the Gibbon, but in
all the genera of the old world baboons and monkeys, and in most of the
new world forms, including the Marmosets.*
