Experimental Methods ’ and ‘ Physiology of 
the Organism as a Whole’ a new paragraph 
entitled ‘General Physiological Phenom- 
ena,’ or something similar. 
Regarding one of these general phenoma 
a further word may be said. It has been 
thought best to give ‘ Fatigue’ a special 
place, numbered 35, under both ‘ Muscle’ 
and ‘ Nerve.’ This is probably wise, but if 
it is recognized here, why not elsewhere, 
and why is not the same number reserved 
for itin other groups? Under ‘Spinal Cord’ 
85 signifies ‘ Relation to Sensations’; and 
under ‘ Cerebral Hemispheres’ it signifies 
‘Tracts of Association and Commissures.’ 
Doubtless any scheme of bibliographical 
classification must be guilty of inconsisten- 
cies, but there seems no necessity for this 
one. 
I need not emphasize that I am greatly 
interested in the proposed catalogue, and I 
trust that nothing, not even differences of 
opinion regarding the scheme of classifica- 
tion, will prevent its prompt inauguration.

P. PSYCHOLOGY. 
A scHEmeE of classification for psychology 
has not been submitted with the other 
schedules. This is unfortunate, as the sub- 
ject-matter of psychology and its classifica- 
tion require careful consideration. This 
can scarcely be given in Great Britain, 
where the science is more backward than in 
Germany, France and the United States. 
The Zeitschrift fiir Psychologie und Physiologie 
der Sinnesorgane and the Psychological Review 
publish annual bibliographies and the Index 
of the Psychological Review is republished in 
the Année psychologique. It is to be hoped 
that the committee of the Royal Society 
will consult these journals and profit by 
their experience. The Psychological Index for 
1898 contains 2,558 titles, has been issued 
within three months of the close of the year, 
and is sold for $1.00. The total cost of the 
SCIENCE. 173 
Psychological Index (500 copies) is about 
$250. For the book catalogue of the Royal 
Society’s plan the cost per science with 
2,500 titles is estimated at $1,700 (which 
does not include the real work of classifi- 
cation done by the regional bureaus), and 
the volume is to be sold for $5.00. It is by 
no means certain that the somewhat cum- 
brous machinery proposed will furnish a 
better bibliography of psychology than that 
of the Psychological Review, and it does not 
appear that psychology will profit greatly 
by the International Catalogue unless the 
card catalogue is undertaken. ‘This I re- 
gard as far more important than the book 
catalogue. 
While no schedule for psychology has 
yet been proposed, there is a certain 
amount of psychology in the other sched- 
ules. I do not understand why the ob- 
solete psychological classification of physies 
has been partially followed. ‘Theory of 
Wave Motion’ is given as a sub-heading 
under ‘ Vibrations, Waves and Sound’. 
Heat with a sub-heading ‘ Radiation’ is 
given earlier, while ‘ Light’ comes later. 
There is given a heading ‘ The Sensation of 
Sound’ under Physics, and one on ‘ Hear- 
ing’ under Physiology. In both sciences 
we find,e. g., a sub-heading ‘ Limits of 
Audition dependent on Intensity and 
Pitch.’ In neither science is there a corre- 
sponding heading for Vision. Sensation and 
Perception should be confined to the sched- 
ule for Psychology.

Q. ANTHROPOLOGY. 
Tur classification of Anthropology sug- 
gested in the ‘ Report of the Committee of 
the Royal Society of London’ does not seem 
to be very systematic. It does not quite 
exhaust the subject-matter of anthropology, 
and, on the other hand, certain topics are 
repeated under different headings. In 
drawing up a schedule of this kind it
