That the date at which a book was last revised 

 should be indicated either on the title-page or 

 iu a bibliographical note. 



(2) Bibliographical Note. — That the biblio- 

 graphical note should, when possible, be 

 printed on the back of the title-page, in order 

 that it might not be separated therefrom in 

 binding. 



(3) Impression, Edition, Reissue. — That for bib- 

 liographical purposes definite meanings should 

 be attached to these words when used on a title- 

 page, and the following are recommended : Im- 

 pression. — A number of copies printed at any 

 one time. When a book is reprinted without 

 change it should be called a new impression, to 

 distinguish it from an edition, as defined below. 

 Edition. — An Impression in which the matter 

 has undergone some change, or for which the 

 type has been reset. Reissue. — A republication 

 at a different price, or in a different form, of 

 part of an impression which has already been 

 placed on the market. 



(4) Localization. — When the circulation of an 

 impression of a book is limited by agreement to 

 a particular area, that each copy of that impres- 

 sion should bear a conspicuous notice to that 

 effect. 



Addendum. — In cases where a book has been 

 reprinted many times, and revised a less num- 

 ber of times, it is suggested that the intimation 

 to that effect should be as follows: e.g.. Fif- 

 teenth Impression {Third Edition). This would 

 indicate that the book had been printed fifteen 

 times, and that in the course of those fifteen im- 

 pressions it had been revised or altered twice. 



GENERAL. 



The Academy of Natural Sciences of Phila- 

 delphia has received from Miss Anna T. Jeanes 

 a gift of $20,000, to be invested and known as 

 the Mary Jeanes Museum Fund, the income to 

 be used for general museum purposes. This is 

 a gratifying instance of continued interest in 

 the welfare of the Academy, which has received 

 substantial benefits from members of Miss 

 Jeanes' family during the last forty-five years. 



The conference of astronomers and physicists 

 held at the Yerkes Observatory in 1897 was so 

 successful that it has been decided to hold a 

 conference this year at Harvard College Obser- 



vatory. It will be in session on Thursday, 

 August 18th, and the two following days, being 

 thus simultaneous with the meeting of the 

 American Mathematical Society and immedi- 

 ately preceding that of the American Associa- 

 tion. 



The fund collected for the Huxley Memorial 

 now amounts to £3,346. The marble statue to 

 be placed in the Natural History Museum is be- 

 ing carried out by Mr. Onslow Ford, and the 

 medal for the Royal College of Science has been 

 completed by Mr. F. Bowcher. About £1,300, 

 which it is hoped will be materially increased, 

 will be left and will be used for a third memorial. 

 The Scientific Memoirs, making a fourth me- 

 morial, are, as we have already stated, in course 

 of publication by Messrs. Macmillan & Co. 



The Academy of Natural Sciences of Phila- 

 delphia has conferred the Haydeu Memorial 

 Geological Award for 1898, consisting of a 

 bronze medal and the interest of the endowment 

 fund on Professor Otto Martin Torell, the Di- 

 rector of the Geological Survey of Sweden, in 

 recognition of his distinguished services to geo- 

 logical science. 



Haevaed University has conferred the de- 

 gree of Doctor of Laws on the eminent chemist, 

 President James Mason Crafts, of the Massa- 

 chusetts Institute of Technology. 



Peofessor O. C. Marsh, of Yale University, 

 has been elected an honorary member of the 

 Geological Society of London. 



The Paris Academy of Sciences has nomi- 

 nated as its first choice M. Lippmann, and as 

 second choice M. Appell, for the vacant place 

 in the membership of the Bureau des longitudes. 



Professor H. A. Loeentz, of Leyden, and 

 M. Emile Picard, of Paris, have been elected 

 foreign members of the London Mathematical 

 Society. 



Professor A. Weismann, Professor B. 

 Grassi and M. Hippolyte Lucas have been 

 elected honorary members of the London Ento- 

 mological Society. 



Nature announces the death, at the age of 

 seventy-two, of Sir James Nicholas Douglass, 

 F. R. S., late Engineer-in-Chief to the Hon. 

 Corporation of Trinity House. During his ten-
