room is granted free of charge to qualified investigators, and any 
one wishing to undertake investigation of biological problems will 
be given all possible opportunity. Courses of study have been 
designed especially for high school teachers and for advanced uni- 
versity students, the former devoting themselves to methods of field 
work and preservation of material for laboratory use, and acquiring 
methods of laboratory work in connection with study of typical 
forms. For the latter, advanced courses in embryology, morpho- 
logy, entomology, plant ecology, botany, etc., are offered. The 
students taking such courses can secure for them university credits 
covering equivalent courses in the university curriculum. It is 
needless to say chat the opportunities for field observation, collect- 
ing, and the laboratory study of representative forms are most 
favorable. For special advanced courses in embryology, and par. 
ticularly those pertaining to microscopical technique, the more 
elaborate equipment of the university is of course preferable. 
NOTES ON THE FLORA OF SANDUSKY. 
W. A. Kellkrman. 
The visitor or student at the Lake Laboratory will find in the 
neighborhood of Sandusky a flora in many respects peculiar and 
richer in species perhaps than in any other region of similar area in 
the state of Ohio. For our knowledge of the Sandusky plants we are 
indebted mainly to the continued and energetic explorations of E. 
L. Moseley, teacher of botany in the Sandusky High School. Our 
visits to the region have been numerous, and many weeks have been 
spent in herborizing during the last few seasons. Mr. Moseley’s 
Sandusky Flora (Ohio State Academy of Science, Special Papers 
No. 1 ) and additions by myself and Mr. Griggs reported before the 
Academy of Science, and published in 1 he Ohio Naturalist, Vol. 
1, fully represent our knowledge of this interesting flora to date. 
In the “Sandusky Flora,” page 2, Mr. Moseley states that “the 
surpassing richness of the Sandusky flora is not due to the fact that it 
includes islands within its territory, for scarcely any of its species- 
are confined to the islands; nor is it in a very large measure due to 
the fact that it includes species that are confined to the lake shore;, 
but rather to peculiarities of climate and geological features, both 
of which depend to some extent on the proximity of the lake.” 
Space will allow reference, to but few of the interesting and rarer 
plants. On Cedar Point and a few other places the Prickly pear r 
Opuntia humifusa, appears in great abundance, but is reported for 
no other stations in Ohio. The illustration (Fig. 1) shows a patch of 
this plant, and also indicates the sparse vegetation in the open sandy
