SYSTEMATIC INDEX TO PSYCHE, VOL. 3. 
(According to the Dewey decimal system.) 
By GEORGE DIMMOCK. 
[The Index to volume 2 of Psyche was based upon the Dewey decimal classification (Amherst, author, 1876), 
which had, however, by its author, been developed only to three places of decimals. For all extensions of 
the system into greater detail the author of that index was solelv responsible. In the use of the system some 
errors were committed, and in its extension some ij consistences, which haye been avoided in the present 
index. The authorized extension of the system, the publication of which has been expected soon, for the last 
two years or more, dit not appear until October 1885. The final revision of the following index, mostly in 
manuscript, was not therefore possible unti! after that date. This index has now beer’ made to correspond, 
in its details, with the new edition of the Dewey decimal classification and relative index (Boston, Library 
Bureau, 1885), a work indispensible to every possessor of a library, or worker with literary material. 
In addition to the correction of errors, as compared with the index to volume 2 of Psyche, a few changes 
have had to be made in consequence of minor changes (which are however great improvements) in the author- 
ized index itself. B: Pickman Mann.]
