metp:orology and allied subjects. 241 



T. C. Mendenhall (now of Colftmbus, Oliio) has prepared a memoir 

 upon the meteorology of Tokio for the year 1877, which has been pub- 

 hshed by the University of Tokio. It would seem meteorological obser- 

 vations are also made and published by the Sapporo Agricultural 

 College under the supervision of William Wheeler, professor of math- 

 ematics, and also made at the Imperial College of Engineering, where 

 they have been in charge of Professors Ayrton, Perry, and Dyer, suc- 

 cessively. Besides all these the Japanese meteorological office pub- 

 lishes an official series. The admirable work of Professor Mendenhall 

 will probably be continued by his successor. Prof. H. M. Paul (formerly 

 of the Naval Observatory, Washington), and it is hoped may serve 

 as a model for the numerous other meteorologists and observers of 

 Japan. 



It seems specially desirable that some observing stations should be 

 established in the northern portion of the Japanese Empire. (Later in- 

 formation is at hand to the eflect that a Japanese storm signal office 

 has been established by the government in charge of the well-known 

 German observer, Dr. E. Knipping.)

A second edition of Mohn, Grundziige cler Meteorologie^ was published in 

 Berlin, 1879. Besides numerous improvements in the charts and tables, 

 this work is especially distinguished by the incorporation therein of 

 the recent progress in dynamical meteorology. 



Dr. A. Eitter has published (Hanover, 1879) a work embracing the 

 results of studies hitherto published in Poggendoff's Annalen^ and 

 dealing with many problems relative to the atmosphere of the earth, 

 the sun, and other planets. The full title is, Anwendungen der mecJian- 

 isclien Wdrmetheorie auf l:osmologische FroMeme. iSechs Ahhandlungen 

 iiher die Constitution gasformiger WeWciJrper, Hanover, 1879. {Z. 0. G. 

 HL, XV, 1880, p. 150.) 



The subject of a bibliography for meteorology was reported on in the 

 congress at Kome by Dr. G. Hellmanu, who interests himself exceedingly 

 in this subject, and who certainly ex^jresses the views of all in saying 

 that the necessity for such a work is felt on all sides, and that its publica- 

 tion would truly be an important step in the progress of science. Some 

 preparation had already been made towards realizing this idea, especially 

 by Reuss, Poggendorff', Struve and others. The propositions made by 

 Hellmann to the Meteorological Congress were commended to the favor- 

 able action of the international committee, whose action, however, has 

 been delayed by the want of funds. General Hazen has secured for 

 the United States Army Signal Office the extensive card-catalogues 

 compiled by Symons, of Loudon, and Abbe, in Washington, and proposes 

 soon to publish these as a small but welcome contribution toward the 

 exhaustive bibliography which is so much desired. Meanwhile the
