intensities and heat seems to have no effect, 

 except in the absence of light, when they mi- 

 grate to the colder area. Experiments also 

 show that heat does not act in the same way 

 as light upon the organism. 



H. S. Jennings points out that in infusoria 

 and in certain rotifers, besides the radial and 

 bilateral types there is a third type, the spiral 

 or at least one-sided, asymmetrical type of 

 structure with a definite relation to the 

 method of movement and life. In the rotifers 

 this asymmetry affects the internal organs as 

 well as the external features which cause the 

 spiral swimming. 



The only cytological paper is by R. Floyd, 

 who describes the nerve cells of the cockroach 

 under various kinds of preservation. He con- 

 cludes that all nervous studies must be con- 

 trolled by study of the living tissue. The 

 thoracic ganglion cells have no evident cell 

 walls. The cytoreticulum is studied, but no 

 classification of the cells found was possible. 



Last to be mentioned is the paper by W. E. 

 Castle and G. M. Allen on the heredity of 

 albinism and Mendel's law. They have ex- 

 perimented with mice, guinea-pigs and rabbits, 

 and find that complete albinism is always re- 

 cessive. A suggestion is made to account for 

 the phenomena of mosaics, and it is pointed 

 out that cross-breeding frequently brings out 

 latent characters and that this probably af- 

 fords the explanation of many cases of rever- 

 sion. 



In closing this synopsis of the volume the 

 reviewer may be allowed to praise the mechan- 

 ical execution of the work. The plates — pro- 

 duced by lithography, heliotype and other 

 photo processes — ilhistrate the papers. The 

 proof-reading has been done in a careful man- 

 Tier, and probably the work owes not a little 

 of its many excellencies to its editor. Dr. G.

SOCIETIES AND ACADEMIES. 

 THE ANTHROPOLOGICAL SOCIETY OF WASHINGTON. 



The 355th meeting was held on February 

 9. A letter from Miss Fletcher was read in 

 which she stated that, owing to sickness, she 

 would not be able to deliver the presidential 

 address. A letter from Dr. Daniel Folkmar 

 describing the anthropological work he is 

 carrying on in the Philippines was read by 

 the secretary. 



Dr. Ales Hrdlicka exhibited cremated hu- 

 man bones from the Choptank River, Md., 

 collected by Dr. Elmer Reynolds, and stated 

 that they are interesting as the first evidence 

 of cremation in the eastern United States 

 except in Florida. Dr. Reynolds, who was 

 present, described the conditions under which 

 the remains were found. 



The first paper of the evening, by Mr. W. E. 

 Safford, discussed the question, ' Were the 

 Aborigines of Guam Ignorant of the Use of 

 Fire?' Mr. Safford showed in the clearest 

 manner the origin of the myth that the 

 Chamorros of Guam were fireless at the dis-
