(Cytology, Physiology and Psychology) being 

 under the immediate supervision of men emi- 

 nently titted for their work. 



The course in Cytological Research will be 

 conducted by Professor Watase, with the as- 

 sistance of Mr. W. H. Packard. The course is 

 designed for a limited number of students who 

 are prepared to begin investigation. A special 

 problem will be assigned to each member of the 

 class, and methods of dealing with it will be 

 suggested. The laboratory work will be ac- 

 companied by a series of lectures on genei'al 

 cytological subjects, designed to give a view of 

 the field of cellular biology as a whole, and at 

 the same time to indicate the bearings of the 

 problems under investigation. 



The course in General and Comparative 

 Physiology will be conducted by Dr. Loeb, as- 

 sisted by Drs. Norman, Lyon and Mathews, 

 and will consist of laboratory work and lec- 

 tures. The following is a brief outline of the 

 work : 



I. The Tropisms of Animals. Galvauotro- 

 pism, Heliotropism, Geotropism and Compen- 

 satory Motions, Chemotroj)ism, Heterotropism 

 in sessile and free forms. 



II. Effects of External Influences upon Liv- 

 ing Matter (lack of oxygen, acids and alkalies, 

 temperature, etc.). 



III. Physiological Morphology. Experiments 

 on Growth and Development, Regeneration 

 and Heteromorphosis. 



IV. Comparative Physiology of the Central 

 Nervous System and Comparative Psychology. 



V. Comparative Physiology of Digestion. 



VI. Comparative Physiology of Secretion. 



VII. Micro- chemistry. 



In Comparative Psychology, Dr. Edward 

 Thorndike will give a course of lectures on the 

 Sense-powers, Instincts, Habits and Intelligence 

 of Animals, and will direct the work of a few 

 students in this department. 



Opportunities for work in Botany are espe- 

 cially inviting. Drs. Davis and Moore, as heads 

 of the department, will have general charge of 

 the laboratory. 



The course of lectures in Plant Morphology 

 and Physiology is supplied by such a strong 



corps, and the subjects are of such scientific 

 importance, that we copy the program in full : 



A COURSE OF LECTUEES ON PLANT MORPHOLOGY 

 AND PHYSIOLOGY. 



First Week, July 5-12.— Erwin F. Smith, 'Bac- 

 teria'; D. T. MaoDougal, ' PhysioloKical Subjects';

 phyte in the Arohegoniates and Flowering Plants.'

 uiings, ' Lichens ' ; L. M. Underwood, ' The Evolu- 

 tion of the Hepaticfe ' ; Eodney H. True, ' Plants 

 and Poisons.'

 matogenesis, Development of Embryo Sac, and Fe- 

 cundation in Gymnosperms ' ; C. 0. Townsend, 

 ' Physiology of the Plant Cell.' 



Fourth Week, July 26-August 2.— J. M. Macfar- 

 lane, 'Plant Irritability'; G. F. Atkinson, 'Higher 

 Fungi.' 



Fifth Week, August 2-9.— J. M. Macfarlane,

 Henry Kraemer, ' The Unorganized Contents of the 

 Cells of Plants. ' 



Sixth Week, August 9-16.— D. M. Mottier, ' Cyto- 

 logical Studies on the Pollen and Embryo-sac of An- 

 giosperms'; D. P. Penhallow, 'Paleobotany.' 



Within the last few years workers at Wood's 

 Holl have derived great profit from the free 

 discussion of various biological methods, facts 

 and theories. During the coming summer 

 there will be three seminars : The Neurological, 

 Biological and Botanical — a series of lectures 

 on Zoological Technique, and the customary 

 course of ' Evening Lectures.' The latter are 

 designed to present the results of research in 

 different lines and departments, in so far as 

 these are of general interest. 



There are thirty names on the list of ofBcers 

 of instruction, and fifty-four names on the list of 

 lecturers. In these two lists fully thirty-five 

 educational institutions are represented.

 TO THE PHILIBPINES. 

 De. Geo. F. Becker, the expert economic 

 geologist, who, early last summer, was sent by 

 the Director of the U. S. Geological Survey, 

 under a cooperative arrangement with the War 

 Department, to Manila to make a reconnais-
