low-grade mental defective. — Prof. R. Dodge : The 

 relation of psychology to special problems of the 

 Army and Navy. — Dr. J. R. Angell : Relation of 

 psychology to the National Research Council. The 

 supporting scientific societies elect representatives who 

 compose the several divisions of the Council, and 

 these in turn, comprising, as a rule, about tv^enty 

 men selected for their eminence in their particular 

 branch of work, come together and determine the 

 special needs and opportunities for the improvement 

 of research in their own fields. Special attention is 

 paid to the possibilities of bringing about effective 

 co-operation among research men and research 

 agencies. Scientific investigation has hitherto been 

 largely individualistic, and the most pressing need 

 at the present moment is not so much the expansion 

 of research agencies, although this is desirable, as 

 the more effective employment of those already in 

 existence.— Dr. B. Ruiiil :" Psychological methods in 

 business and industry. — Prof. A. J. Jones : The 

 individual in education. ^^Prof. R. W. Wood : In- 

 visible light in war and peace.

Royal Society of Tasmania, June 8.— Mr. L. Rodway, 



vice-president, in the chair.— G. H. Hardy : Aus- 

 tralian Stradiomiidae. The paper included a description 

 of new species. — H. H. Scott and C. Lord : Studies of 

 Tasmanian mammals, living and extinct. Part ii. 

 The paper was divided into two sections, and dealt 

 mainly with the skeleton of Nototherium MitchelM 

 recently obtained from the north-west coast of Tas- 

 mania. The first section gave a riswmi of the his- 

 tory of the genus, and the second dealt with the 

 osteology of the cervical vertebrae. The authors 

 desire to show that the species was one essentially 

 adapted for aggressive warfare. They point out that 

 whereas the skulls of A^. Mitchelli and N. tasmanicum 

 at least (with the possibilitv of other species) are 

 equally large and weighty, yet their cervical vertebrae 

 show marked differences : one being an exaggeration 

 of the standard of the modern wombat in about the 

 same ratio of power (N. tasmanicum), while the 

 other shows an additional power with interspinal 

 muscles and paddings, suitable to the resisting of 

 great shocks in the long axis of the head and 

 vertebra?.
