8GIBNTIFIG JOURNALS AND ARTICLES 

 The American Naturalist for January con- 

 tains the following articles : ' Note on the 

 Habits of Fierasfer,' by Edwin Linton, de- 

 scribing the manner in which the fish enters 

 tail first the body of a holothurian. ' Records 

 of Pennsylvania Fishes,' by Henry Fowler, 

 giving definite localities for many species. 

 ' Specific Name of Necturus maculosns' by 

 F. C. Waite. Tetradactylus is unavailable as 

 a specific name, not because it refers to a 

 generic character, but because it was not ap- 

 plied as a scientific name ; what Lacepede wrote 

 was Proteetetradactyle. Under ' Volvox for 

 Laboratory Use,' Bertram G. Smith tells how 

 it may be kept and J. A. Cushman records 

 seven species of ' Ostracoda from Southeastern 

 Massachusetts.' 



The Museum's Journal of Great Britain has 

 for its leading articles ' How to Promote In- 

 terest in Museum Collections,' by H. Con- 

 wentz, and ' Children and the Cult of the 

 Beautiful,' by Beatrice V. Vernon. The first 

 applies particularly to what may be termed 

 local museums, and we doubt if many of the 

 suggestions would prove to be practicable in a 

 large institution. Miss Vernon's article deals 

 largely with art museums and Mr. Harlan I. 

 Smith will find in it methods akin to his 

 interrogative label. 



The Zoological Society Bulletin for Janu- 

 ary is an unusually good number. We can 

 only note among other articles those on ' The 

 Goat Herd,' ' An Almost Extinct Bird ' (the 

 California Vulture), the ' African Vipers,' 

 ' The Frigate Birds ' and ' Collecting for the 

 Aquarium.' It is announced that the last of 

 the large buildings are expected to be com- 

 pleted by the end of 1908, and that the attend- 

 ance for the year was 1,300,000. A green 

 turtle received at the aquarium weighed 540 

 pounds; the length of the upper shell was 

 4 feet 6 inches. It may be seen from this how 

 large a thousand-pound turtle would be. The 



attendance at the aquarium during 1906 was 

 something over 2,000,000. 



The Museum News, of the Brooklyn Insti- 

 tute for February announces the installation 

 of a group of Atlantic walrus. The principal 

 article in the Children's Museum section is 

 on the muskrat and states that in the Hacken- 

 sack marshes the muskrats seem to live in 

 houses throughout the year, the summer 

 houses being more loosely buiilt than the 

 winter home. 



The Fortnightly Review for January con- 

 tains an article by E. Hay Lankester de- 

 scribing in some detail the work carried on 

 at the British Museum during the past eight 

 years under his immediate supervision. 



SOCIETIES AND ACADEMIES 



THE ST. LOUIS CHEMICAL SOCIETY 



At the regular meeting of the society on 

 January 14, Mr. A. H. Kelling presented a 

 paper entitled ' Sewage Purification.' Pollu- 

 tion of water supplies, and the danger of in- 

 fection resulting from the habits of the house 

 fly, were dwelt on as showing the importance 

 of the subject. The three methods by precipi- 

 tation, by means of sewage farms, and by 

 means of septic tanks and filtration were then 

 treated in considerable detail. After the dis- 

 cussion, which followed the presentation of 

 this paper. Dr. Andrews presented a paper, 

 which favorably discussed the probable appear- 

 ance of some ofiicial interpretations of certain 

 regulations contained in the last issue of the 

 U. S. Pharmacopoeia, with reference to the 

 Pure Food and Drugs Act.

DISCUSSION AND CORRESPONDENCE 

 genetic logic 



To the Editor op Science: Dr. Tawneys 

 criticism of my book on ' Genetic Logic,' in 

 your issue of February 1, calls for a word or 

 two of comment. 



He is mistaken in supposing the ' dualism 

 of control ' as I develop it represents my own 

 view of the nature of reality. 



Being the ' knower's logic ' that I am de-
