128 Chronicles of Science. [Jan., 



various contents are not as available as might be wished to most 

 British readers. Accordingly we hail with great pleasure the 

 announcement contained in the lieport of the Meteorological Com- 

 mittee, that it is intended to publish shortly an English edition of 

 the temperature charts for the South Atlantic Ocean which appeared 

 in the work entitled ' Ondersoekingen met den Zee-Thermometer,' 

 Utrecht, 1861 (Researches with the Sea Thermometer). This 

 year the attention of M. Cornehssen has been directed in a special 

 way to the sea-surface temperature round the south point of Africa, 

 where the alternations of cold and warm water are so frequently 

 noticed — the domain of the dangerous gales of those seas. We are 

 glad to say that this work has been pubhshed in English. It con- 

 tains charts giving the temperature for each square degree during 

 the different seasons, which are of great interest and value. 



With regard to the land- work of the Institute, the Jaarboek, 

 (Year-book) has now reached its nineteenth annual volume. 



In Prussia Professor Dove has brought out during the last two 

 years the results of the monthly means of the meteorological elements 

 for the four years 1864-67, with the five-day means of temperature, 

 obtained by the discussion of the observations furnished by the 

 Meteorological Institute, and also the first portion, relating to tem- 

 perature, of a research into the climatology of North Germany for 

 the last twenty years. The preface to this work contains much 

 interestinsf information : we learn from it that the number of stations 

 in connection with the Institute has now reached 160, and as the 

 instruments have all been rejjeatedly verified, the data derived from 

 them are to be thoroughly trusted. It is, however, very satisfactory 

 to hear from Professor Dove, the highest li'sang authority on the 

 subject, that having compared carefully the results furnished by 

 the present system with those obtained m previous years, before the 

 Institute was in existence and consequently before the regular 

 verification of the instruments had commenced, he finds that the 

 conclusions yielded by the older materials are very slightly difterent 

 from those now in process of deduction. The works in question, 

 like the former ones of the Institute, have appeared as a portion 

 of the publications of the Eoyal Statistical Bureau, and compose 

 Nos. 12, 14, and 15 of that series. 



North Germany is also commencing the work of Ocean Meteor- 

 ology, and an office, entitled the Nord-deutsche Seewarte, has been 

 established at Hamburg, under the superintendence of Ilerr W. von 

 Freeden, formerly Rector of the Navigation School at Elsfleth, near 

 Bremen. In fact the entire organization is to a great extent due 

 to the energy of the Director, whose long experience of similar 

 investigations loads us to cherish the best hopes for the success of 

 the new undertaking. 



In Norway Professor H. Mohn has recently furnished a number
