in such manner that several subdivisions of the subject will be 
open to investigators by the codperation of various members of 
the staff; in the addition of special facilities in teratology, and in 
provision for experimental work in acclimatization and influence 
of climate on plants. The position formerly held by Dr. Ander- 
son in Columbia University is now filled by Dr. Tracy Hazen, 
who will participate in directing investigations on the morphology 
and taxonomy of the algae. 
The principal subdivisions of research subjects are as follows : 
Morphology of Algae.—Study of the structure, development 
and life-history of the Algae. Field and laboratory. Dr. 
Howe; Dr. Richards; Dr. Hazen. 
Morphology of Fungt.— Study of the structure, polymorphism 
and development of the Fungi, including culture methods. 
Field and laboratory. Professor Underwood; Mr. Earle. 
Mor phology of Bryophyta. — Study of the structure, develop- 
ment and life-history of Musci and Hepaticae. Field and labo- 
ratory. Professor Underwood; Mrs. Britton; Dr. Howe. 
Morphology of Pteridophyta. — Study of the structure, develop- 
ment and life-history of Ferns and Fern-allies. Field, garden,
