REPORT OF THE SECRETARY. 9 



It is the present practice to publish occasionally memoirs from the 

 Contributions in separate form, to be afterwards combined in a volume 

 when enough have been completed. Only one such memoir of Contri- 

 butions has been prepared during the year, which is a communication 

 by the Secretary under the title of The Internal Work of the Wind. 



A volume of the Contributions is now passing through the press, and, 

 though its full description belongs more properly to a later report, it 

 may be stated here that its subject is oceanic ichthyology, that it is 

 prepared by Dr. G. Brown Goode and Dr. Tarleton H. Bean, and that 

 the work, which will be a joint publication of the Institution and the 

 National Museum, is an exhaustive dissertation on the fishes of the 

 ocean depths and particularly those of the North Atlantic Basin. 



As another memoir of Contributions, I had hoped to complete the 

 publication of the photographic volume on the moon, to which I have 

 called attention in j)revious reports, but the science of photograjihy 

 has not yet progressed sufiBciently to meet the requirements of the 

 work. 



Other memoirs are in preparation, to which attention will be called 

 in my next report. 



Miscellaneons Collections,— The Smithsonian Miscellaneous Collec- 

 tions is an octavo series intended to include works of scientific value, 

 but of less original importance than the Contributions to Knowledge. 



Thirty-five complete volumes of Collections have been issued since 

 the Institution was founded, and four additional volumes are now in 

 preparation, parts of volumes 35 to 38 having already been published. 



Volume XXXV of the Collections will include the Smithsonian Mete- 

 orological, Geograjihical, and Physical Tables. These tables are 

 intended to replace in modernized form and with newer knowledge the 

 Guyot Meteorological and Physical Tables, first published in 1852, and 

 which has since been a standard work of reference for investigators. 

 The first part of the volume, the Meteorological Tables, was published 

 last year. The Geographical Tables, prepared by Professor Woodward , 

 have been put in type during this year, but not yet issued ; these tables 

 make a volume of 288 pages. The Physical Tables are now being pre- 

 pared by Prof. Thomas Gray, and may be expected to be completed in 

 1895. 



Volume XXXVI is a single work, a very comprehensive Select Bibli- 

 ography of Chemistry, covering the four hundred years from 1492 

 to 1892, prepared by Dr. H, Carrington Bolton. This volume was pub- 

 lished in 1893, but the first edition was soon exhausted, and it became 

 necessary to issue a second edition during the present year. 



There is now in progress the preparation of a supplement to this 

 Bibliography of Chemistry, to include titles of works down to 1895, as 

 well as some additions to the first volume. It is expected that the 

 supplement will number about 5,000 titles. 



This bibliography actually aims to include everything that is of
