The second summer session of the Laboratory of Biology of Tufts College 

 will open at South Harpswell, Maine, on June fifteenth and continue until about 

 September first. Courses in Invertebrate Zoology, Vertebrate Zoology, Botany, 

 and Embryology will be given, as well as opportunity for special research work. 

 The laboratory is well equipped with apparatus for ordinary investigations and 

 has a library of several hundred volumes and pamphlets selected with reference 

 to the work to be done. These advantages are placed at the disposal of 

 students for the consideration of a very reasonable fee. Communications should 

 be addressed to the director, J- S. Kingsley, Tufts College, Mass.
