The Ohio Naturalist. 
LVol. XIII, No. 1, 
MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, October, 7 1912. 
The meeting was called to order by President Barrows. The 
secretary being absent Professor Schaffner was appointed secre¬ 
tary pro tem. No minutes of the previous meeting being at hand, 
this order was omitted. 
The papers of the evening consisted of reports of the past 
summer’s work and observations. 
Prof. F. L. Land acre gave a report of neurological work done 
at the University of Chicago. The type studied was Rana 
vipiens. 
Prof. J. Id. Schaffner gave some observations on various forms 
of Amaranthus retroflexus. A number of striking leaf-patterns 
were found in Ohio and Kansas. Seeds were collected and will be 
planted in order to determine the status of these forms. He also 
spoke of the nature and distribution of trees in the prairie regions 
of Kansas. 
Prof. C. H. Goetz spent some time in Northeastern Nebraska 
and in Florida. In Nebraska the bluffs and hills facing the 
northeast are wooded while those facing the opposite direction are 
without trees. In Florida, forest conditions are not very favor¬ 
able. Eucalyptus trees do not grow well and the soil seems 
unsuitable in many places for vigorous tree growth. 
Prof. A. Dachnowski studied the question of absorption and 
wilting point of plants and also the relation of root systems to 
each other and to the substratum in order to determine the amount 
of antagonism or correlation present. The latter observations 
were made on plants at Buckeye Lake. He regarded the mutual 
relation as being a physical rather than a chemical or biological 
one. 
Prof. W. M. Barrows reported on making an accurate map of 
Cedat Point. The topographic maps were found to be incorrect 
in some particulars. 
After the president was given authority to appoint a committee 
to nominate officers, the society adjourned. 
John H. Schaffner, Secretary pro tem.
