SCIENCE.

which are essentially Magellanic, and all three 

 of the littoral species are related to the Ma- 

 gellanic fauna. The examination of the ana- 

 tomy of the various forms preserved afforded 

 opportunity for morphological notes of inter- 

 est, especially those bearing on the relations of 

 Modiolarca, Philohrya, etc. The cephalopods 

 were represented only by beaks of cuttlefish 

 found in the stomachs of seals and penguins 

 more or less demoralized by digestive fluids 

 and incapable of identification. 



These brief indications will show how much 

 this series of memoirs is likely to add to our 

 knowledge of the Antarctic regions, and how 

 much science is indebted to the intrepidity of 

 the explorers and observers on board the Bel- 

 gica. W. H. Dall. 



SCIENTIFW JOURNALS AND ARTICLES. 

 With the March issue the Bulletin of the 

 Michigan Ornithological Club (quarterly) en- 

 ters upon its fifth volume. The issue opens 

 with the account of ' The Discovery of the 

 Breeding Area of Kirtland's Warbler,' by 

 Norman A. Wood, which is practically a full 

 life history of this race species with an ac- 

 count of its breeding habits. The article is 

 illustrated by a frontispiece showing the male 

 and female beside a nest; a photo of the egg 

 and other views showing the nesting situation 

 and nature of the country (Oscoda County, 

 Mich.). Chas. C. Adams follows with an 

 article on the ' Migration Eoute of Kirtland's 

 Warbler,' which is illustrated by three maps. 

 Under the head of Michigan Ornithologists is 

 given a full-page plate of A. H. Griffith, direc- 

 tor of the Detroit Museum of Art. Professor 

 Walter B. Barrows, of the Michigan Agri- 

 cultural College, announces ' A Forthcoming 

 Bulletin on Michigan Birds ' to be published 

 by the "agricultural college, and requests in- 

 formation from students in the state. Space 

 is given to the Michigan Audubon Society 

 which was organized February 2Y, 1904, as an 

 auxiliary to the Michigan Ornithological 

 Club, for the protection of birds in the state.

EXPERIMENTAL PSYCHOLOGY. 



A MEETING of experimental psychologists 

 was held at Cornell University, April 4 and 5. 



The session of Monday morning was opened 

 by Professor L. Witmer with a paper on the 

 ' Laboratory Investigation of Backward Child- 

 ren.' This was followed by a discussion of 

 various phases of the reaction experiment, in 

 the course of which the following papers were 

 read : Professor C. H. Judd, ' Analysis of 

 Movements made in Simple and Complex Re- 

 actions '; Dr. G. M. Whipple, 'The Simple 

 Reaction as a Test of Mental Ability ' ; Pro- 

 fessor C. E. Seashore (read in absence), " The 

 Psychological Term ' Observer.' " Professor 

 Witmer also spoke on ' Shortest Reaction 

 Values,' and upon the ' Difference between 

 Sensory and Muscular Reactions.' At the after- 

 noon session, Professor Judd read a paper on 

 ' Eye Movements studied by Photography; with 

 Special Reference to the Miiller-Lyer, Pog- 

 gendorff and Zollner Figures ' ; Mr. H. C 

 Stevens outlined a ' Study of Attention by the 

 Method of Expression ' ; and Dr. J. W. Baird 

 spoke upon recent investigations in perimetry. 



The session of Tuesday morning was opened 

 by Professor E. C. Sanford, with a report of 

 Dr. Kuhlmann's experiments upon idiots. Mr. 

 C. E. Ferree emphasized the importance of 

 adaptation in fluctuations of the visual atten- 

 tion, and Professor W. B. Pillsbury discussed 

 the ' Influence of Closing Eyes upon Attention 

 Waves.' At the afternoon session Professor 

 Pillsbury read a paper on ' An Apparatus for 

 Investigating Torsion during Eye Movement, 

 with ■ some Results ' ; Professor Judd spoke 

 upon the ' Imitation of Tones, With and With- 

 out Distraction ' ; Professor Sanford demon- 

 strated a novel form of color mixer, and Mr. 

 G. H. Sabine a ' Speed Regulator for the von 

 Frey Limen Gauge.' The remainder of the 

 afternoon was devoted to a business meeting, 

 and to an inspection of the psychological 

 laboratory. At an evening session, held in 

 the psycho-educational laboratory. Dr. Whip- 

 ple spoke upon 'Some Difficulties in the Use
