of the Cold Spring for use in the aquaria and troughs. This 

 water is pure, has the same low temperature throughout the 

 year, and is the water used so successfully by the New York 

 State Fish Commission in hatching and growing salmon, 

 trout, and other food fishes. The Laboratory is also sup- 

 plied with an abundance of salt-water, which is pumped up 

 from the harbor into a reservoir, from which it runs into the 

 Laboratory. 



The station is provided with two small row-boats and a 

 naphtha launch, together with nets, trawls, and dredges for 

 use in collecting and dredging. The main Laboratory is fur- 

 nished with both fresh and salt-water aquaria, with a Becker 

 microtome and a Minot microtome, together with many 

 smaller instruments and appliances. Near the main Labora- 

 tory is a photographic room, with a dark room and a work- 

 room adjoining. These rooms are provided with a general 

 photographic outfit, a photomicrographic apparatus, a helio- 

 stat, and the necessary appliances for practical photography. 



Each student is provided with dissecting instruments, 

 chemicals, and glassware to be used in the dissection, prepa- 

 ration, and study of tissues. Students who own microscopes, 

 or who can borrow them for the summer, are respectfully re- 

 quested to bring them to the Laboratory for their own individ- 

 ual use. Microscopes will be provided for those students who 

 cannot provide themselves with instruments. 



The New York Fish Commission very kindly grants the 

 use of the main Laboratory room for biological study during 

 the summer months, when it is uot required by the work of 

 the Commission. 



The other buildings and the grounds used by the Biological 

 Laboratory are the property of the Wauwepec Scientific So- 

 ciety of Cold Spring Harbor, and the use of them is gener- 

 ously donated by the Society for the benefit of the instruc- 

 tors, specialists, and students who are in attendance at the 

 Laboratory. 



A general course in biology adapted to meet the wants of 

 those who desire to obtain a general and working knowledge 

 of biology either for use in teaching or in preparation for 

 special work will be given during the first six weeks of the 

 session. It will consist primarily of laboratory study of 

 specimens illustratiug leading types of animal life. The 

 practical work will be accompanied by lectures giving an 

 outline of systematic zoology, for the purpose of showing the 

 relations of the forms studied toother animals. The lectures 

 will also touch upon various matters of general biological in- 

 terest. The types studied will comprise forms of life repre- 

 sented in the waters of Long Island Sound. 



Accompanying this course of laboratory work and lectures, 

 instruction will be given in methods of mounting objects and 

 in the preparation of microscopic sections. Opportunity will 

 also be given for collecting and surface skimming. 



A special feature of the Laboratory will be an extended 

 course in the methods of bacteriological research. The course 

 will consist of laboratory work on the culture and propaga- 

 tion of bacteria, the identification of species, and of lectures 

 and demonstrations by the director. The number of students 

 admitted to this course is limited, and only those who are 

 well prepared by previous study and experience in biological 

 or medical work will be admitted to the course. 



Students who pursue the general course of instruction 

 during the summer, and who have time for extra work, are 

 given the instruction and facilities necessary to enable them 

 to carry on special investigations, while those students who 

 have already gained the knowledge and experience which is 

 provided by the general course, will be permitted to give 



their entire time to special work. No special courses will be 

 laid down in advance, but each student will be at liberty to 

 arrange with the director of the Laboratory for such a course 

 or courses as may be practicable. 



Each lecturer will be provided with extra laboratory space 

 in which to carry on his own private investigations so long 

 as he shall remain at the Laboratory, and will not be called 

 upon to give any instruction outside of his lectures and such 

 directions for work as may accompany his lectures. 



The Laboratory will open for the season on Wednesday, 

 July 6. The regular session for students will continue from 

 that date until Wednesday, Aug. 31. 



The tuition fees will be, — for the full term, eight weeks, 

 $25; for the first six weeks, $20; for the first four weeks, $15; 

 for the last four weeks, $15. 



The tuition is payable $10 on registration as a student, and 

 the balance during the first week of attendance. Each stu- 

 dent will be entitled to attend all the lectures delivered at 

 the Laboratory, to the use of the Laboratory and its ap- 

 pliances, subject to the regulations established by the director 

 and board of managers, and to all the facilities for collecting 

 specimens which are possible with the launch and other boats 

 provided by the Laboratory. 



The number of students for the season of 1892 is limited to 

 thirty. The Board of Managers reserve the right to admit 

 as students only those whose training qualifies them to make 

 the best use of the Laboratory and its facilities for study and 

 research. Applicants for admission to the Laboratory should 

 state what work in botany or zoology they have already 

 done, and what course they would like to pursue the present 

 season. 



A good reference library will be placed at the service of 

 students, and a collection of algae will serve to guide students 

 in marine botany. In addition to the regular lectures given 

 in connection with the laboratory work, evening lectures 

 will occur two or three times a week, illustrated by the aid 

 of a magic lantern. The lantern is provided with a vertical 

 attachment and with large and small cells, in which forms 

 of life may be placed and their structure exhibited on the 

 screen. A microscopic attachment to the lantern will enable 

 lecturers to demonstrate points in minute anatomy, and a 

 large collection of lantern slides of biological subjects will 

 furnish the means for comparison of many allied forms and 

 structures. 



The evening lectures will be open to the public, and per- 

 sons interested may secure admission to the entire course. 



Arrangements have been made with residents at Cold 

 Spring Harbor to provide very good and comfortable rooms, 

 with board, a few minutes' walk from the laboratory, at rates 

 varying between six and eight dollars per week. 



A new dining-room has been provided close by the Labora- 

 tory, and excellent board will be provided to such officers 

 and students as may choose to avail themselves of it at $5 per 

 week. It is expected that a majority of the officers and 

 students will board at the dining-room and take rooms at the 

 residences near by. The expense in this case will be as be- 

 fore, between seven and ten dollars for board and room. 



Accommodations can be secured at either of the large, ex- 

 cellent, and quiet hotels that overlook the harbor, and are 

 fifteen minutes' ride by boat or carriage from the Laboratory, 

 at rates varying between eight and fifteen dollars per week, 

 according to the size and location of rooms. The hotels are 

 known as the Glenada, Laurelton, and Forest Lawn. 



Full information will be given concerning rooms and 

 board to anyone who signifies an intention of becoming a
