SCIENCE. 



ticable the phenomena observed. Among 

 others the problems of buried mountains, 

 bolsen deserts, 'mesas and the structure of the 

 western Sierra Madres have had much new 

 light thrown upon them, if they have not been 

 solved. Edmund Otis Hovey. 



NEWSPAPER SCIENCE. 



To THE Editor of Science: In the interest 

 of the dignity of scientific research I wish to 

 repeat the statement, made by me on a former 

 occasion, that I have not authorized the sen- 

 sational reports concerning any work; and 

 that I am in no way responsible for the idio- 

 syncrasies of our daily press.

A BIOGRAPHICAL DIRECTORY OP AJIERICAN MEN 

 OF SCIENCE. 



The undersigned is compiling a ' Biograph- 

 ical Directory of American Men of Science.' 

 It was begun as a manuscript reference list 

 for the Carnegie Institution of Washington, 

 but arrangements have now been made for its 

 publication. The book should be ready in the 

 autumn, nearly 4,000 biographical sketches 

 being in type. The proofs have been corrected 

 by those concerned, but in order to secure as 

 great accuracy as possible a revised proof will 

 be sent in the early autumn. 



This letter is written with a view to secur- 

 ing biographical sketches from those living in 

 North America who have carried on research 

 work in the natural or exact sciences but who 

 have not received proof of a sketch for cor- 

 I'ection. Some of those who were asked to 

 send the information required did not reply 

 even in answer to a second and third request, 

 and there are, of course, many who should be 

 included in the work but who for one reason 

 or another did not receive the request for 

 information. 



It is intended that each biographical sketch 

 shall contain information, as follows: 



1. The full name with title and mail address, 

 the y)art of the name ordinarily omitted in corre- 

 spondence being in parentheses. 



2. The depailment of investigation given in 

 italics. 



.3. The place and date of birth. 



4. Education and degrees with dates. 



5. Positions with dates, the present position be- 

 ing given in italics. 



(i. Temporary and minor positions. 



7. Honorary degrees and other scientific honors. 



8. Membership in scientific and learned socie- 

 ties. 



9. Chief subjects of research, those accomplished 

 being separated by a dash from those in progress. 



The undersigned will be under great obli- 

 gations to those men of science who will send 

 him biographical sketches of themselves or 

 who will secure sketches from those who 

 should be included in the work — those who 

 live in the United States, Canada, Newfound- 

 land, Mexico or Cuba, and who have con- 

 tributed to the advancement of one of the 

 following sciences: mathematics, astronomy, 

 physics, chemistry, geology, botany, zoology, 

 pathology, physiology, anatomy, anthropology, 

 psychology. 



The compiler of the book hopes that any 

 assistance given him to make it as complete 

 and accurate as possible will be at the same 

 time a contribution to the organization of 

 science in America.

THE NOMENCLATURE OF TYPES IN NATURAL 

 HISTORY. 



Practical work in the arrangement and 

 cataloguing of ' types ' and other museum 

 material has shown us that the present nomen- 

 clature is not yet sufficient for critically dis- 

 tinguishing all the different classes of such 

 specimens. Further, some of the terms which 

 have been proposed for the purpose are al- 

 ready employed in other ways: for instance, 

 homotype is in use in biology; monotype is 

 the name of a printing machine; autotype is 

 the term for a printing process. We wish, 

 therefore, to submit the following system of 

 nomenclature; and we hope that, in making 

 it more complete, we have provided a scheme 

 which will render efficient service in the 

 labeling and registration of types and typical 

 material.
