A limited number of private rooms is avail- 

 able for other investigators in botany. Appli- 

 cations for use of these rooms should be made 

 to Dr. George T. Moore, Water Mill, New 

 York. 



Subjects for investigation in zoology, physi- 

 ology or botany will be assigned to those whose 

 previous training qualifies them to begin re- 

 search. The student may select his teacher in 

 investigation, subject to the approval of the 

 latter. 



II. Instruction. — The courses of instruction 

 are six weeks each, including about four weeks 

 in July and two in August. Each course re- 

 quires the full time of a student. They are 

 so graded that the student may supplement 

 his college instruction by courses leading 

 up to research, or he may take the more ele- 

 mentary courses in zoology or general morphol- 

 ogy of plants. Credit for courses taken in the 

 Marine Biological Laboratory is generally 

 given by colleges and universities and also by 

 boards of education of various cities, on cer- 

 tificate of the instructor in charge. It has 

 been decided to add two courses to those given 

 in recent years, viz., a course in embryology 

 and one in general morphology of plants (see 

 below). 



1. Zoological instruction, season of 1908, will 

 be in charge of Winterton C. Curtis, assistant 

 professor of zoology. University of Missouri, 

 assisted by Paul M. Eea, professor of biology. 

 College of Charleston, and director of the 

 Charleston Museum ; Mas Morse, tutor in nat- 

 ural history. College of the City of New York ; 

 Lawrence E. Griffin, professor of biology, Mis- 

 souri Valley College; Edward E. Wildman, 

 instructor in biology, Central High School, 

 Philadelphia, and John W. Scott, Westport 

 High School, Kansas City. 



Although Dr. L. L. Woodruff, instnictor in 

 biology, Yale University, is leaving the staff 

 in zoology for that in embryology, he has con- 

 sented to give the lectures on protozoa in 1908. 



The conduct of the work in this subject 

 will not differ substantially from the plan 

 which has proved successful in recent years. 

 Lectures and laboratory work are supplement- 

 ed by extensive collecting trips, during which 



the student has opportunity to observe the 

 methods of marine collecting and to study a 

 wide range of marine forms in their natural 

 surroundings. 



2. The course in embryology will be in 

 charge of Professor Gilman A. Drew, of the 

 University of Maine, Orono, Maine, assisted 

 by Dr. L. L. Woodruff, instructor in biology, 

 Yale University, and Dr. W. E. Kellicott, 

 professor of biology in the Woman's College 

 of Baltimore. 



It is the aim of this course to meet the needs 

 of those who desire to get an insight into 

 fundamental problems, and to serve as a basis 

 for those who desire to begin independent in- 

 vestigation. It will supplement the usual col- 

 lege course in embryology, laying special 

 weight on questions of general importance 

 that can best be approached by the study of 

 living marine material. 



The work will include the study of organ- 

 ization, maturation and fertilization in the 

 egg, the early development, types of gastrula- 

 lation, and the effects of different conditions 

 on development. The advantage of following 

 the actual process of development in the living 

 egg, instead of comparing a few preserved 

 stages of development, can not be overesti- 

 mated. 



The course will be accompanied by lectures 

 delivered by members of the staff and by other 

 investigators working at the laboratory. For 

 the course in embryology, the course in zool- 

 ogy or its equivalent is a prerequisite. 



3. The course in comparative physiology 

 will be in charge of members of the same staff 

 as in 1907, viz. : 



Albert P. Mathews, professor of physiological 

 chemistry, University of Chicago. 



E. P. Lyon, professor of physiology, University 

 of St. Louis. 



Ida H. Hyde, professor of physiology. Univer- 

 sity of Kansas. 



R. S. Lillie, instructor in comparative physi- 

 ology. University of Pennsylvania. 



A. J. Carlson, assistant professor of physiology, 

 University of Chicago. 



Edward Gr. Spaulding, assistant professor of 

 philosophy, Princeton University.
