174 SMITHSONIAN MISCELLANEOUS COLLECTIONS [vOL. 45 



A grant from the Hodgkins Fund to Professor Morris W. Travers, 

 of University College, London, after the customary reference, ex- 

 amination, and discussion, was recently approved. This research 

 deals largely with the liquid properties of hydrogen, and is reported 

 on in detail in a memoir by Professor Travers, shortly to be issued 

 by the Institution under the title. Researches on the Attainment of 

 Very Loiv Temperatures. 



Two memoirs. Ionised Air and The Structure of the Nucleus, by 

 Doctor Carl Barus, who worked under the Hodgkins Fund, have 

 recently been published by the Institution. On account of the 

 immediate interest attaching to these investigations. Doctor Barus 

 also was allowed to publish preliminary reports of his progress 

 in the scientific journals. The investigation on the structure of 

 nuclei is a continuation of the experiments with ionized air, and 

 outstanding questions in the first memoir have been answered in 

 the second. Both volumes appear among the Contributions to 

 Kno7vledge. This research is interesting not only in its own 

 methods and results, but because of its agreement with the data 

 obtained by other investigators from different experiments and 

 theoretically dift'erent points of view. 



A recent grant on behalf of Mr. E. C. Huffaker is for the construc- 

 tion and practical application of a device intended to produce a 

 uniform and measured flow of air through a tube of any desired 

 diameter. This apparatus is primarily designed for use in con- 

 nection with investigations in the line of biology, and it has already 

 been applied to exact experiments in the development of the embryo 

 of the egg. It is hoped that by means of this invention facts may be 

 established which will prove of practical value. 



Since 1899, Terrestrial Magnetism and Atmospheric Electricity, 

 a journal of which Doctor L. A. Bauer is the editor, has been aided 

 annually by a moderate grant from the Hodgkins Fund in the form 

 of a subscription for a specified number of copies of the journal, to 

 be sent out to specialists and educational establishments, as directed 

 by the Institution. 



While any general allotment of the income from the Hodgkins 

 Fund for the purposes of investigation is precluded by the terms 

 of the bequest, an application by an investigator who can comply 

 with the conditions which, in accordance with the stipulations of 

 the donor, necessarily govern the expenditures from the Fund, is 

 sure of serious consideration.
