In a recent number of SctENcE, Professor 
Carus has presented most serious objections 
to the bibliographical methods proposed by 
the Royal Society’s Committee. For the 
professional zoologist such a verdict needs 
no criticism. For no one else can possibly 
claim to have such a wealth of experience 
at his disposal as this Nestor of scientific 
bibliography. 
Severe as the criticisms of Professor Carus 
are, they may be supplemented by others 
which will make the case against the pro- 
posed schedules still stronger. Book bib- 
liographies may entirely dispense with arbi- 
trary symbols; the real test of a numer= 
ical system is to be sought in the application 
of the system to cards. Since I have been 
the pioneer in the publication of an extensive 
card catalogue of scientific literature, it was 
natural that the editors of Science should 
invite me to express in their columns a judg- 
ment upon the new proposals; but my 
criticisms, if frankly expressed, would have 
to be so severe that I was loath to take a 
position which would seem to place me in 
opposition to an enterprise to which I had 
already pledged allegiance. I feel, however, 
that I cannot withhold the following state- 
ment: 
No one without extensive experience can 
possibly foresee the complications that arise
