Texi-hooh of Physiological Chemistry. By 



Olof Hammarsten. Translation by John 



A. Handel. Seventh edition. Wiley and 



Sons, New York. 



Another edition of Hammarsten's " Text- 

 book of Physiological Chemistry " is novsr 

 available in English (translation by Mandel). 



Outside of the material contained in the 

 first two chapters of the last edition which 

 now have been combined into one, the arrange- 

 ment of the older editions has been retained. 

 Chapter for chapter, almost every subject 

 treated occupies very nearly the same number 

 of pages as before. Nevertheless, this edition 

 is far from being a mere reprint. The newer 

 observations and references are usually to be 

 found — sometimes in place of older observa- 

 tions (and references), but more frequently 

 as additions. In the field of metabolism, a 

 field always somewhat scattered and sub- 

 merged in " Hanunarsten," the new edition 

 will prove disappointing to American stu- 

 dents just as the older editions have been. 

 Most of the facts are there, but it takes a 

 brave and diligent student to find them. 



The index is very full, but its usefulness to 

 students is not so great as it might be be- 

 cause it still lacks expert systematization. 

 The first subject that the reviewer happened 

 to look up in the index was mucin; sixteen 

 references are given) the first is entirely mis- 

 leading and the most essential references are 

 tucked away in the middle of the long list. 



Index and all, however, American biochem- 

 ists are always pleased to see one more edition 

 of the book which more than any other is 

 kept within reach for daily consultation.

NOTES ON ENTOMOLOGY 

 Two recent parts of Das Tierreieh treating 

 of the hymenopterous superfamily Proctotry- 

 poidea'^ are almost monographic in character. 



Both are by the Abbey J. J. Kieffer and 

 treat of almost 1,800 species in over 130 

 genera. An illustration is given of nearly 

 every genus, and there is an introductory por- 

 tion treating of the external morphology. 

 Many of the species are from our country. 



India is sufficiently distant from both Eu- 

 rope and America and its fauna has been suffi- 

 ciently unknown to have been selected as the 

 probable place of origin of many types of 

 animals. Its insect fauna, however, is now 

 becoming better known through numerous 

 books ; three have come to hand recently. One 

 by T. B. Fletcher^ deals with the insects of 

 southern India. There is an introductory ac- 

 count of insects, and life histories of many 

 species representing most of the families. A 

 second large work is by E. P. Stebbing^ and 

 is devoted to accounts of the life history of 

 and the damage wrought by the forest beetles 

 of India. Unfortunately it contains the de- 

 scriptions of various new species. The third 

 work is purely economic and treats of the pests 

 of various crops.* It consists of 84 leaflets 

 with plates, mostly colored, of insect and 

 fungous enemies of field crops. 



Several microlepidopterists had shown that 

 certain Tineid larvse are of different shape and 

 habit at different stages of development. 

 Tragiirdh^ has investigated these forms and 

 arranges them in two sections, the tissue eaters 

 that bite and eat the parenchyma of the leaf, 

 and the sap-feeders, that take only liquid, 

 The former method is the more primitive, the
