24 The Ohio Naturalist. [Vol. 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 tern. No ininutes 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. Landacre gave a report of neurological work done 

 at the University of Chicago. The type studied was Rana 

 vipiens. 



Prof. J. H. vSchaffner 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. Eucal^q^tus 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 substratmn 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 foimd 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 tern.
