The laboratory has been considerably en- 

 larged and now consists of four two-story 

 buildings, with forty private rooms for the 

 exclusive use of investigators, and seven 

 general laboratories. It is supplied with 

 aquai-ia, a steam launch, boats, dredges, 

 and all the apparatus necessary for collect- 

 ing and keeping alive material reserved for 

 class work or research. 



A Dejiartment of Laboratorj- Supply has 

 been established in order to facilitate the 

 work of teachers and others at a distance 

 who desire to obtain material for study or 

 for class instruction. Circulars giving in- 

 formation, prices, etc., may be obtained on 

 application. 



The forty private laboratories are dis- 

 tributed as follows ; Zoology, twenty-two ; 

 Phj'siologj', eight ; Botany, ten. These 

 rooms are rented at one hundred dollars to 

 colleges, societies or individuals. 



The general laboratories for research are 

 for the use of students engaged in special 

 work under the supervision of the Director 

 and his assistants, and for advanced courses 

 preparatory to beginning investigation, such 

 as the course in Embryology. There are 

 forty-two tables, of which Zoology has twen- 

 ty-two, Physiologj' ten, and Botany ten. 



Applications should be made to Professor 

 C. O. "Whitman, University of Chicago, 

 Chicago, 111. 



EMBRYOLOGY. 



The course in Embryologj' extends from 

 July 10th to August 17th. The aim is not 

 only to master the details of development. 



but also to acquire a thorough knowledge 

 of preparing surface-views, imbedding in 

 paraffin and celloidin, staining, mounting, 

 drawing, reconstructing modeling, etc. The 

 study is mainly confined to the fish egg as 

 the best type for elucidating vertebrate de- 

 velopment ; but the eggs of amphibia and 

 other vertebrates as well as some inverte- 

 brates will receive attention. The fee is 850. 



IX^'ESTIGATIOX. 



The course in Investigation extends fi'om. 

 Jul J- 3d to August 17th. For those pre- 

 pared to begin original work, ten tables are 

 reserved in Zoiilogy, and the same number 

 in Physiology and BotanJ^ 



Special subjects for investigation are as- 

 signed to the occupants of tables, and the 

 supervision of the work is so divided that 

 each instructor has the care of but three or 

 four students. In this way all the advan- 

 tages of iudi^•idual instruction are secured. 

 The fee is 650. 



SEMIXAK. 



A Seminar has been instituted, and, 

 though specially designed for members of 

 the class in Embryology and beginners in 

 investigation, it is open to all. The tliii'd 

 volume of the Biological Lectures will be 

 made the basis of discussion. Most of the 

 authors of these lectui-es will be present ; 

 and from two to three mornings will be de- 

 voted to the consideration of each lecture 

 and such questions as may be raised. 



LABORATORY' FOR TEACHERS AXD STUDENTS 



IX AXATOjrr. 

 Ix the Laboratory for Teachere and 

 Students in Anatomy, which is open from 

 July 2d to August 30th, two coui-ses are 

 ofiered : the first, in Invertebrate Anatomy, 

 and the second, a newlj' arranged couree 

 in A''ertebrate Anatomy. The fee for either 

 course is 840.
