Die Palaeobotanische Literatur. By W. J. 
Jonemans. Zweiter Band—Die Erschein- 
ungen des Jahres 1909 und Nachtrige fur 
1908. 
Tn the issue of Science for August 26, 1910, 
the writer published an account of the initial 
volume of Jongman’s “ Paleobotanical Bibli- 
ography,” which covered the year 1908. The 
second volume of this laborious undertaking 
has just been distributed. It is from the press 
of Gustav Fischer, of Jena, and aims to in- 
elude all of the contributions to paleobotanical 
literature that were published during 1909. 
Additions for 1908 that were omitted in the 
first volume are included and all of the species 
described or mentioned in the discussions, 
together with the geological horizons, are ar- 
ranged alphabetically, and this, the main part 
of the work, is preceded by a list of the con- 
tributions numbered chronologically and ar- 
ranged by authors. 
The present volume makes a book of 417 
pages, or about twice the size of volume one, 
and fully maintains the high standard of the 
latter. It is indispensable to the working 
paleobotanist. Botanists, geologists and bib- 
liographers also owe Dr. Jongmans a debt of 
gratitude. 
Individuals and institutions can cooperate 
in the continuation of this valuable work by 
sending their publications promptly to the 
author in care of the Royal Herbarium at 
Leiden, Holland.

SCIENTIFIC JOURNALS AND ARTICLES 
In the Philippine Journal of Science, Sec- 
tion D, No. 4, Dean C. Worcester describes 
newly discovered breeding places of Philippine 
sea birds, illustrated with half-tone plates 
which show great numbers of boobies and

217 
terns which are apparently without any fear 
of the photographer. The same author also 
notes a probable hybridism among boobies. 
R. OC. McGregor reports the capture of Puf- 
finus chlororhynchus Gould off the coast of 
Luzon, and describes a new species of noddy 
tern, Micranous worcesteri, from Cavilli 
Island in the Sulu Sea. R. W. Shufeldt’s 
article on the skeleton in the flying lemurs is 
concluded. A. S. Pearse presents notes on the 
habits of Thalassina anomala (Herbst), and 
concerning the development of frog tadpoles 
in sea water. Section B, No. 4, con- 
tains two papers on amcbe found in the 
Philippine Islands. In one Ernest Lin- 
wood Walker makes a comparative study 
of the amcebe in the Manila water sup- 
ply, in the intestinal tract of healthy persons, 
and in ameebic dysentery and shows that all 
hitherto cultivated amcebe are non-pathogenic, 
but that the true pathogenic amcba can not 
be cultivated; in the other Andrew Watson 
Sellards discusses immunity reactions with 
amcebse. Weston P. Chamberlain presents a 
statistical study of typhoid fever in the Philip- 
pine Islands; a map shows the distribution of 
typhoid fever in the Islands. Horace D. 
Bloombergh presents data relative to the Was- 
sermann reaction in syphilis, leprosy and yaws. 
In Section A, No. 4, Alvin J. Cox discusses 
Philippine soils and some of the factors which 
influence them, the chief among these being 
the division of the Philippine Islands into re- 
gions because of types of rainfall. Raf. A. 
Herrmann presents a theory on the formation 
of the central Luzon plain. Benjamin T. 
Brooks describes essential oil from Michelia 
champaca L. and discusses its chemical consti- 
tution. He also gives a study of a number of 
other new Philippine essential oils and re- 
views the fluctuations in the value of ylang- 
ylang.
