scribes ' The Birds of a Marsh ' near Keuka 

 Lake, N. Y. The fifth series of 'Birds and 

 Seasons ' is devoted to the birds to be seen and 

 studied in August and September, as noted by- 

 contributors from Boston to Stockton, Cal., 

 with suggestions for the season's study and 

 reading. 



The first number of The Museums' Journal of 

 Great Britain is issued promptly, and naturally 

 commences with a statement of the objects of 

 the Museums' Association and its journal. The 

 address of the President, Sir William Turner, 

 delivered at the Edinburgh meeting of the As- 

 sociation follows, and this is devoted to the his- 

 tory of ' The Public Museums of Edinburgh.' A 

 sample is submitted of ' A Museum Label,' de- 

 scriptive of British pottery and as criticism is 

 invited it may be said that it will strike some 

 as rather long, although it is undeniably replete 

 with information. ' Museum Notes,' ' At Home 

 and Abroad, ' complete the number. 



In the issue of Science for April 26, 1901, 

 there was given a somewhat detailed account 

 of a proposed journal for the statistical study 

 of biological problems, suggested by Professor 

 Karl Pearson and Professor E. F. R. Weldou. 

 We are glad to learn that the first number of 

 the journal, which is called Biometrika, will be 

 published in October. Professor C. B. Daven- 

 port, of the University of Chicago, is one of 

 the editors, the others being Professors Pearson 

 and Weldon. The journal will be published by 

 the Cambridge University Press and will ap- 

 pear about four times a year. The following 

 papers are ready or in preparation : 



' Biometry ' : FnANCis Galton. 



' On the Terminology and Notation of Bio- 

 metric Investigations.' 



' Variationsstatistische Probleme und Mate- 

 rialien ' : Professor Dr. F. Ludwig.

An Index to the Experiment Station Record,

The Senate of the University of London 

 has decided to publish periodically an ofiicial 

 organ, to be called The London University Ga- 

 zette, which will contain class lists, new regula- 

 tions, dates of examinations, etc. The paper 

 will appear about twenty times in the first year, 

 beginning in October.
