are almost equally divided in number between the cryptogams

b. Columbia Herbarium. Additions aggregating about 

 18,842 specimens were made to this collection during the 

 year. This great increase is due to the acquisition of the 

 Morong herbarium, which is now made a part of the Colum- 

 bia herbarium, by the action of the Trustees of Barnard Col 

 lege and Columbia University. A conservative estimate of 

 the contents of the Morong herbarium, is 18,000 specimens. 



Fully 3,500 sheets, containing about 12,475 miscellaneous 

 specimens were mounted and have been distributed in the 

 cases. These additions are mainly from the Jaeger moss 

 herbarium, but otherwise they are selected and valuable 

 specimens and greatly increase the value of the collection 

 A comparsion of the contents of the Garden harbarium as 

 given above with the present contents of the Columbia her- 

 barium as shown in the following paragraph will show how 

 admirably the two herbaria supplement each other and form 

 together the largest collection in America. 



The Columbia University herbarium was begun early in the 

 century by Dr. John Torrey, and contains the material upon 

 which his botanical writings, extending over half a century, 

 were based. On this as a foundation the present Columbia 

 herbarium was built. Mr. John J. Crooke enriched it by 

 two valuable collections ; the one that of Professor C. J. 

 Meisner, of Basle, Switzerland, and the other that of the late 

 Dr. A. W. Chapman, of Appalachicola, Florida. A few 

 years later the mosses, and many of the hepatics and lichens 

 accumulated by Mr. C. F. Austin, were incorporated in it, 

 while the quite recent acquisitions of great size and impor- 

 tance, are the famous collection of mosses brought together 

 from all parts of the world by the late Dr. J. G. Jaeger, of 

 Switzerland, and the Morong herbarium. To this ample 

 nucleus, Dr. Torrey's successor, Dr. N. L. Britton, while 

 professor at Columbia, and his associates, added continually 

 by securing collections from all parts of the globe, and by 

 special collecting trips to various parts of North and South 

 America.
