not only in every public library, but on the 

 study table of every serious student in every 

 department of science. 



The above report is submitted not as an 

 elaborated plan, but as a suggestion of the 

 end to which effort should be directed. 

 Your committee would further express the 

 hope that some plan may be put into oper- 

 ation at an earlier date than the year 1900, 

 the time suggested in the circular of the 

 Koyal Society. 



In accordance with the views above set 

 forth the committee respectfully recom- 

 mends the adoption by the University 

 Council of the following votes: — 



1. That, in the opinion of the University 

 Council, the establishment of a catalogue of 

 scientific literature to be maintaiued 

 through international cooperation is both 

 desirable and practicable. 



2. That a copy of this report be trans- 

 mitted to the Royal Society as the sugges- 

 tion of a way tu which this plan may be 

 successfully carried out. 



3. That the Corporation be requested 

 to contribute a suitable sum toward the 

 carrying-out of this enterprise, provided the 

 plan finally adopted by the Royal Society 

 shall appear to the University Council to be 

 practicable.

SCIENTIFIC LITEBATURE. 

 Systematic Survey of the Organic Colouring Mat- 

 ters. By Drs. G. Schultz and P. Julius. 

 (Translated and edited, with extensive 

 additions, by Aethue G. Green, F. I. C, 

 F. C. S., Examiner in Coal-tar products

 tute.) London and New York, Mac-

The industi-y of the organic coloring mat- 

 ters has within a comparatively few yeai-s 

 grown to enormous dimensions, and it is 

 becoming difficult even for the specialist in 

 organic chemistry to keep track of the new 

 products. In this valuable book a carefully 

 classified list is presented of 454 dj'e stufis 

 which have been patented, and many of 

 these are now iu extensive use. All of them 

 are derived indirectly fi-om coal-tar. Under 

 each dj^e we find the common name, together 

 with other names sometimes used ; the scien- 

 tific name ; the empirical formula ; the 

 constitutional formula ; the method of pre- 

 paration ; the year of discovery ; the name 

 of the discoverer ; reference to the patents 

 granted ; behavior with reagents ; shade 

 and dyeing properties, and method of em- 

 ployment. The original German edition is 

 so well known, and it has acquired such a 

 high reputation that any words of praise for 

 the book would be superfluous. The trans- 

 lator's work seems to have been done with 

 care, and he has not only furnished a trans- 

 lation of the original, but brought the work 

 up to date, that is to say, up to the date of 

 publication, for it must be borne in mind 

 that a book treating of organic coloring mat- 

 ters bears to the general subject somewhat 

 the relation that an instantaneous photo- 

 graph bears to the rapidly moving object 

 which it attempts to represent. 



The authors tell us that : " The average 

 quantitj'^ of gas tar worked up per annum 

 is given at 350,000 tons for England, and 

 530,000 tons for the whole world, whilst the
