It should also be pointed out that the plan 

 of the courses as mapped permits ready ad- 

 justment of the observed quantities for closed 

 areas, in accordance with the potential hypoth- 

 esis, and it may permit to a certain degree 

 the testing of the accuracy of this assumption, 

 though as regards the latter more can be said 

 at the end of a year's work. 



While it is not anticipated that any marked 

 irregularities in the distribution of the earth's 

 magnetism will manifest themselves over the 

 deep waters of the Pacific, it may confidently 

 be expected that in the neighborhood of the 

 islands and along the coasts distortions and 

 irregularities will be revealed. With the aid 

 of the results of the detailed magnetic survey 

 of the United States and Alaska, opportunity 

 will, therefore, be afforded of studying the 

 effect of the configuration of land and water 

 upon the distribution of the magnetic forces. 

 The first circuit, passing as it does along the 

 American and Asiatic coasts, will yield es- 

 pecially interesting results in this respect. 

 Thus, for example, along the Aleutian Islands 

 marked local disturbances will be disclosed. 

 Reports are received frequently from mariners 

 in this region regarding the unsatisfactory 

 behavior of the compass; it is, therefore, 

 greatly to be desired that a systematic mag- 

 netic survey of the waters in this region be 

 made. , 



Additional information regarding the ex- 

 pedition will be given later.

THE ELIZABETH THOMPSON SCIENCE 

 FUND. 



The thirtieth meeting of the board of 

 trustees was held at the Harvard Medical 

 School, Boston, Mass., on March 17. The 

 following ofiicers were elected: 



President — Henry P. Bowditch. 



Treasurer — Carles S. Rackemann. 



Secretary— ChsiTles S. Minot. 



The report of the treasurer, showing a bal- 

 ance of income on hand of $1,237.79, was ac- 



cepted and placed on file. The secretary re- 

 ported that the following grant had been 

 made: 



No. 116, $150, to W. Bateson, Esq., for ex- 

 periments on heredity in rabbits, to be con- 

 ducted under Mr. Bateson's direction by Mr. 

 C. C. Hurst. 



Reports of progress were received from the 

 following recipients of grants: 



No. 27. E. Hartwig. 



No. 60. F. Kruger. 



No. 94. A. M. Reese. 



No. 96. H. E. Crampton. 



No. 98. J. Weinzirl. 



No. 101. T. A. Jaggar, Jr. 



No. 103. E. Anding. 



No. 106. W. Valentiner. 



No. 107. M. W. Travers. 



No. 108. B. L. Seawell. 



No. 109. A. Nicolas. 



No. 110. H. S. Grindley. 



No. 111. R. Hiirthle. 



No. 112. W. J. Moenkhaus. 



No. 113. S. P. Fergusson. 



No. 114. W. Rosenthal. 



No. 115. H. S. Carhart. 



No. 116. W. Bateson. 



The work having been completed and pub- 

 lished, it was voted to close the records for 

 the following grants: 



No. 71. A. Nicolas. 

 No. 79. H. S. Grindley. 

 No. 100. H. H. Field. 

 No. 102. E. 0. Jordan. 

 No. 104. W. P. Bradley. 



It was further voted that the work having 

 been completed, the records of the following 

 grants should be closed, when copies of the 

 published results were received by the trustees : 



No. 65. O. Lubarsch. 

 No. 73. J. von Kennell. 

 No. 83. W. L. Tower. 



Mr. F. W. Bancroft, who held grant No. 97, 

 reported that his experiments had been made 

 for the transplantation of .ovaries in rabbits, 

 but that he had not succeeded in obtaining 

 ova from such transplanted ovaries. It was 

 deemed, therefore, inadvisable to continue the 

 research, and it was voted to close the record 

 of his grant, and to allow him to use the ma- 

 terial which he had on hand for other re- 

 searches.
