Harbor during- the coming summer. Eegular 

 class work will begin on Wednesday, July 6, 

 and continue for six weeks. Investigators 

 may make arrangements for using the labo- 

 ratory from the middle of June until the mid- 

 dle of September, or later, if desirous of doing 

 so, but board at the laboratory will not be 

 guaranteed after August 20. Application for 

 admission to the laboratory should be made as 

 early as possible, as the earlier applicants 

 have the choice of rooms in the dormitories, 

 and the number of students receiving instruc- 

 tion is limited to 50. The courses of instruc- 

 tion offered are as follows : 



High-school Zoology by Professors C. B. Daven- 

 port, S. K. Williams and W. M. Wheeler. 



Comparative Anatomy by Professor H. S. 

 Pratt and Dr. D. B. Casteel. 



Invertebrate Embryology by Professor H. E. 

 Crampton and W. J. Moenkhaus. 



Animal Bionomics and Evolution by Professor 

 Davenport. 



Cryptogamie Botany by Professor D. S. Johnson 

 and Mr. A. H. Chivers. 



Plant Ecology by Mr. Forrest Shreve, of Johns 

 Hopkins University. 



Microscopic Methods by Mrs. Davenport. 



Courses in beginning investigations are of- 

 fered, and advanced investigators are offered 

 free use of rooms at the laboratory. The 

 laboratory fee is $30 and room and board 

 are furnished for $6 upward per week. An- 

 nouncements and further information may 

 be obtained from any of the instructors, or 

 from Professor C B. Davenport, University 

 of Chicago. 



The annual meeting of the Michigan Orni- 

 thological Club will be held at the museum 

 of the University of Michigan, at Ann Arbor, 

 on April 2, 1904, in connection with the meet- 

 ings of the Michigan Academy of Science. 



The thirty-eighth meeting of the Eastern 

 Association of Physics Teachers was held in 

 the Newton High School building on Satur- 

 day, March 19. Professor S. W. Stratton, 

 director of the Bureau of Standards, "Wash- 

 ington, D. C, read papers on * The Metric 

 System ' and on ' The Equipment of Physical 

 Laboratory Workshops.' 



A CONFERENCE of tcachers of mathematics, 

 well-attended and representing a large number 



of universities, colleges and high schools, was 

 held on February 22, 1904, in Columbus, Ohio. 

 This conference decided to form an association 

 of Ohio teachers of mathematics and ap- 

 pointed committees to arrange for a meeting 

 to complete the organization. This meeting 

 will be held in Columbus at the Ohio State 

 University on April 2, 1904. The conference 

 extended an invitation to the teachers of phys- 

 ics and chemistry in Ohio to meet in Colum- 

 bus with the teachers of mathematics to form 

 a similar organization, with the suggestion 

 that these several bodies be related in some 

 desirable way under the name of ' The Asso- 

 ciation of Ohio Teachers of Mathematics and 

 Science.' 



The fifteenth International Medical Con- 

 gress will meet at Lisbon April 19-26, 1906. 



We learn from The Geographical Journal 

 that a project has lately been set on foot for 

 the bringing together into one building of all 

 the scientific societies which have their head- 

 quarters in Edinburgh, and a meeting of the 

 fellows of the Royal Society of Edinburgh 

 in support of the proposed scheme was held 

 in the society's rooms on November 26 last, 

 the subject being introduced by a speech by 

 Sir John Murray. The Eoyal Society occu- 

 pies a portion of the building known as the 

 Eoyal Institution, which it shares at present 

 with other public bodies, including the Board 

 of Fishery, the School of Art and the Society 

 of Antiquaries of Scotland, the whole being 

 under the general control of the Board of 

 Manufactures. It has long been thought that 

 the building should be exclusively devoted to 

 scientific purposes, thus, on the one hand, se- 

 curing a community of interests on the part 

 of all its users, and, on the other, facilitating 

 the work of scientific research by the central- 

 ization thus afforded and the avoidance of the 

 dissipation of energy which is to a certain ex- 

 tent the result of the present separation of 

 the societies. It is held that, were the whole 

 building given up to their use, it would be 

 possible to find space for the housing of all 

 the several libraries, including those of the 

 Scottish Geographical and Meteorological So- 

 cieties, besides allotting to each the rooms 

 required for other purposes, and leaving the
