the largest that has ever been brought together from this source. 

 A species of peculiar interest is named PUjctodus howlandi in 

 recognition of help and encouragement given, during the prepar- 

 ation of this important work, by Mr. Henry R. Howland of the 

 Buffalo Museum. 



Number I of Volume XIII (pp. 23 with 18 plates), is on the

6. Guide to the Mineral Collections in the Illinois State Mu- 

 seum; by A. R. Crook. Pp. 294, with 31 plates and 236 text 

 figures. — This is an interesting account of the Collections in the 

 State Museum, numbering nearly 1300 specimens. Numerous 

 illustrations are given, those in half-tone and in color being par- 

 ticularly noteworthy. The volume will be useful not only to 

 those visiting the Museum, but also because of the fullness of its 

 general descriptions to students of minerology. 



III. Miscellaneous Scientific Intelligence. 



1. Report of the Secretary of the Smithsonian Institution, 

 Charles D. Walcott, for the year ending June 30, 1920. — The 

 Secretary states that the total funds of the Institution now 

 amount to $1,083,000 and that the income available for the year 

 was $174,000. Notwithstanding the special funds that have been 

 added since the original gift from James Smith son in 1826, the 

 income at present is quite too small to permit of the work being 

 carried on as liberally as formerly, because of the greatly in- 

 creased costs. However, the researches and explorations for the 

 year have been very varied in subject and locality, not the least 

 important being the work of the Secretary himself in the Cana- 

 dian Rocky Mountains. It is interesting to note that the 

 National Gallery of Arts is in future to be a separate unit under 

 the Institution with Mr. W. H. Holmes as Director. The build- 

 ing, provided by the $1,000,000 given by Mr. Charles L. Freer of 

 Detroit, is now nearly completed and practically ready for the 

 installation of the collections. It is much to be regretted that 

 Mr. Freer did not live to see his generous gift to the Nation put 

 in permanent form. The International Exchange Service has 

 increased largely, the number of packages handled during the 

 year being nearly 370,000, weighing about 500,000 pounds. Al- 

 though several countries are not included in the exchange list, 

 the total number exceeds that of 1914 by over 27,000. The 

 National Museum has acquired about 217,000 specimens, nearly 

 half of these being in zoology. The Museum is now in charge of 

 Mr. W. deC. Ravenel. Mr. Abbot, director of the Astrophysical 

 Observatory, notes the practical completion of volume IV of the 

 Annals. He also mentions the fact that the results for the solar 

 variation for 1917 and 1918 obtained at Mt. Wilson and at 

 Calama, Chile, 4,000 miles apart, agreed very closely. Through
