1895.] The Cold Spring Harbor Biological Laboratory. 233 
The laboratory proposes further to increase its usefulness by 
furnishing material for class work to our schools. Marine 
specimens for school purposes have been difficult and expen- 
sive to obtain. The Cold Spring Laboratory, therefore, will 
furnish common types of marine animals at low prices to such 
schools as need them for work with classes. 
For these reasons the school at Cold Spring Harbor offers 
itself as an especially favorable place for certain classes of 
students. Students in our colleges who wish to complete the 
biological work of the inland schools by practical study with 
animals at the sea shore will find the systematic courses here 
given of great use to them. Public school teachers who need 
a practical knowledge of animals and plants to enable them to 
teach the subjects of zoology and botany in an interesting 
manner to their students; advanced college students who have 
taken elementary work and desire a practical knowledge of 
comparative embryology or advanced zoology; medical 
students whose regular work in the medical school is so 
crowded as to leave them little time for general reading; all 
of these will find the training to be obtained at the summer 
schools, in general biology, of the utmost value. College pro- 
fessors, too, who desire to make collections for their classes and 
to obtain material for their own original work will find a place 
here. All of these classes of students are among the attend- 
ants of the school at Cold Spring Harbor and all find much of 
interest and value in the work at the school. 
While, at the beginning, the object of the school at Cold 
Spring Harbor was to furnish a place of instruction, the more 
_.advanced side of biological work has been by no means 
neglected. The laboratory now in use contains private rooms 
for investigators. The instructors in the school and the college 
professors who have been present with the school in past years 
have been carrying on investigations of original character. 
Every facility is afforded to those advanced workers who 
desire to carry on research, and it is the aim of the manage- 
ment of the school to increase rather than to diminish the 
facilities for investigation, and thus to attract a large number 
of students engaged in research. During the last summer the
