MEETINGS OF THE BIOLOGICAL CLUB. 
FEBRUARY MEETING. 
The meeting of the Biological Club, held in the Zoological lecture 
room on the evening of February 4th, 1901, was presided over by the 
president, Prof. Osborn, about thirty being present. 
Prof. Lazenby presented ‘‘Remarks on Poisonous Plants.” He 
mentioned many of the poisons to which the poisonous properties of 
various plants are due. Many cases of poisoning are caused by 
poisonous fungi gathered with edible mushrooms, and greens 
gathered by persons unacquainted with poisonous herbs. Stramo- 
nium has been known to cause cases of poisoning by being gathered 
in greens. The distribution of jjoisonous plants through the various 
botanical orders was discussed, and the fact was revealed that a 
large percentage of the orders contain such species. 
Prof. Ball spoke on ‘‘Collecting in Colorado.” His remarks on 
both faunal and floral conditions are valuable to all, and especially 
to those who collect in that western state. He emphasized the fact 
that in collecting Hemiptera, general sweeping is not productive of 
the best results. Many of the grasses which grow in that country 
are at least partially recumbent, and for that reason the sweeping 
net misses most of the desirable species. The species of insects 
which feed on these grasses are best taken by searching about the 
roots, or by lifting up the stems and scrutinizing them closely. 
Many new or rare species of Hemiptera have been procured in num- 
bers in this way. 
He exhibited many photographs and drawings which revealed 
the picturesqueness of the country, something of the flora, and the 
difficulties railroad companies experience in getting a track across 
the mountains, and left with many present a desire to see the re- 
markable scenery for themselves, 
MARCH MEETING. 
The Biological Club met in Townshend Hall on the evening of 
March 4, 1901, the lantern being kindly furnished and operated by 
Professor Hunt. 
The board of editors through its secretary, Mr. Griggs, recom- 
mended that the offer of Professor Kellerman to take one-half the 
numbers of the first volume of the Ohio Naturalist for $125.00 be 
accepted ; and that Professors Schaffner, Osborn and Kellerman be 
appointed a committee to consider the disposition of exchanges. 
The report was unanimously accepted by the club.
