plained, for intelligent volition is shown to bea true cause of 
bodily movement, seeing that the cerebration which it involves 
would not otherwise be possible. This monistic theory thus 
serves to terminate the otherwise interminable controversy on the 
freedom of the will; for the theory shows it to be merely a mat- 
ter of terminology whether we speak of the mind or of the brain 
as the cause of bodily movement. That particular kind of phys- 
ical activity which takes place in the brain could not take place 
without the occurrence of volition, and vice versa. All the re- 
quirements alike of the determinist and of the free-will hypotheses’ 
are thus satisfied by a synthesis which comprises them both in 
one. Mr. Romanes afterwards reviewed the opinions of the late 
Professor Clifford upon this subject, and concluded by observing 
that if it were true that the voice of science must of necessity 
speak the language of agnosticism, at least let them see to it that 
the language was pure; let them not tolerate any barbarisms in- 
troduced from the side of aggressive dogma. So would they find 
that this new grammar of thought did not admit of any con- 
structions radically opposed to more venerable ways of thinking, 
and that the often-quoted words of its earliest formulator applied 
with special force to its latest dialects—that if a little knowledge 
of physiology and a little knowledge of psychology incline men 
to atheism, a deeper knowledge of both, and still more a deeper 
thought upon their relations to one another, could only lead men © 
back to some form of religion, which, if it be more vague, will 
also be more worthy than that of earlier days. 
ANTHROPOLOGY.' 
FURTHER CONFIRMATION OF THE POST-MORTEM CHARACTER OF 
THE CRANIAL PERFORATIONS FROM MiIcHIGAN Mounps.—In a 
paper entitled “ Burial Customs of our Aborigines,” read by the 
writer before the Ann Arbor meeting of the American Associa- 
tion, August 28, 1885, two fragmentary crania, recently exhumed 
from a mound on the Detroit river, Michigan, and presenting 
good examples of the peculiar custom of cranial perforation, 
were exhibited as illustrations in the anthropological section. 
The cephalic index of the first specimen would throw it into the 
medium or orthocephalic group, or to follow the nomenclature of 
Professor Broca, the mesaticephalic division. The single circular 
perforation occupies, as usual, a central position at the vertex of 
the skull, being situated on the sagittal suture, about 0.6 of an 
inch back of its junction with the coronal suture. The perfora- 
tion is 0.4 of an inch in diameter, and was probably made in the 
Same manner as were all those I have seen, by a rude stone imple- 
ment rotated by hand. r 
The second specimen is evidently not of as great antiquity as
