MUSEUM OF COMPARATIVE ZOOLOGY. 17 



Assistants in the laboratory and field-work of Geology 5, under 

 the direction of Professor J. B. Woodworth. 



In November and December, 1903, six illustrated public lectures 

 were given in the Geological Lecture Room, on successive Friday 

 afternoons, at 4.30 p.m. The subjects of these lectures were as 

 follows : I. The Natural History of the Diamond. Professor 

 Palache. II. The Climate of the Philippines. Professor Ward. 

 III. The Glacial Geology of Southeastern Massachusetts. Pro- 

 fessor J. B. Woodworth. IV. Evidences for Evolution illus- 

 trated by certain Fossil Types. Professor R. T. Jackson. V. 

 Some Geological Problems of the Yellowstone National Park. 

 Professor Jaggar. VI. The History of Niagara. Professor 

 Davis. 



The Department acknowledges, with great satisfaction, a gift 

 of one hundred dollars from Mr. George P. Gardner, of the Visit- 

 ing Committee appointed by the Board of Overseers, this sum to 

 be expended in building and installing cases in the new Geological 

 Exhibition Rooms. The Department also gratefully acknowledges 

 a gift received, through the generosity of Mr. Alexander Agassiz, 

 from the Museum of Comparative Zoology, of some exhibition 

 cases recently removed from the African Room in that Museum. 

 With these resources, and with a slight addition from the funds 

 of the Department, two exhibition cases have now been erected in 

 the large exhibition room of the Geological Museum, one against 

 the north wall, and one between the windows on the south side. 

 Both cases are ready for the installation of materials for 

 exhibition. 



Professor Shaler gave his regular lectures during the first half- 

 year, and left Cambridge January 2, 1904, on a leave of absence 

 for five months. During his absence, the lectures in Geology 4 

 were given by Professor Jaggar, and those in Geology 14 by 

 Professor R. T. Jackson. 



Professor Davis's work is described on pages 13-15. 



Professor R. T. Jackson reports that the teaching collections in 

 Palaeontology are in good condition. Some additions were made 

 by purchase from Ward's Natural Science Establishment. A 

 number of enlarged photographic diagrams for teaching purposes 

 were added to the laboratory equipment. 



Professor Ward reports an increase in the number of students 

 in Elementary Meteorology (Geology B). Considerable time was 

 devoted to rearranging and systematizing the laboratory exercises
