-` The following courses of instruction are offered : 
In the laboratory for teachers and students in anatomy which will 
be open from July 2 to August 30, two courses are offered : the first, 
in invertebrate anatomy, and the second, a newly arranged course in 
vertebrate anatomy. Either course may be made preparatory to the 
course in embryology. The course in invertebrate anatomy will em- 
brace a study of the more typical marine invertebrates, instruction 
being given by lectures, laboratory work and collecting excursions. 
The lectures are given each morning, and by those who are special- 
ists in the subject under consideration. For laboratory dissection, each 
student is supplied with fresh material, and the entire day is spent in 
study, under the direction of the instructors. Collecting excursions are 
taken on Wednesdays and Saturdays. The steam launch and boats 
are freely used, and methods of dredging, skimming, and general col- 
lecting are explained. The animals studied will be Grantia, Tubularia, 
Campanularia, Metridium, Mnemeopsis, Nereis, Phascolosoma, Polyzoa, 
Bdellura, Molgula, Branchipus, Lepas, Talorchestia, Cancer, Limulus, 
Asterias, Arbacia, Echinarachnius, Thyone, Venus, Sycotypus, Loligo. 
The course in vertebrate anatomy has been arranged for those who 
desire a thorough study of the vertebrate body. Though primarily a 
laboratory course, under the direction of the officers of the laboratory, 
there will be daily lectures upon anatomy, physiology, and kindred 
subjects by the following lecturers: Professor H. P. Bowditch, Dr. F. 
S. Lee, Dr. C. F. Hodge, Dr. O. S. Strong, Dr. C. S. Minot, Dr. J.S. 
Kingsley, Dr. J. P. MeMurrich, Dr. H. F. Osborn. The first week will 
be devoted to the Elasmobranchs, the Dogfish (Galeus) and Skate re- 
ceiving special attention. The second week will be devoted to the 
higher Fishes. During the third week the Batrachia will be studied. 
The fourth week will be devoted to the Reptilia. : 
Instruction in microscopical technique will extend throughout the 
month. Methods of section-cutting, differential staining, ete., will be 
taught, and histological preparations of the more important tissues will 
be made. , 
The fee for either of the above courses is $40.00, payable in advance. 
It covers tuition, material for dissection, dissecting instruments, lab- 
oratory outlines, drawing paper and instruments, slides and covers, 
and a supply of glassware and reagents. The laboratory loans, without 
charge, microtomes and certain other apparatus ; there is a small fee, 
however, for the use of microscopes, and all who can provide them- 
selves with simple and compound microscopes before coming to Wood’s 
Hole, are urged to do so.
