one might decide that the only course to take would be to accept 
the Vienna rules. But no dictum of any convention will prob¬ 
ably ever be binding on the conscience of the average American 
unless all botanists the world over can have a voice in the 
decision. The only correct scientific convention which legislates 
for botanists in general must be one organized on the American 
principle of proportionate representation. In the meantime 
morphologists and ecologists who use plant names only as a 
means to an end will not be able to understand each other 
without the aid of a book of synonyms.

Correction. 
In the paper entitled, “On the Origin of Polar Conjugation 
in the Angiosperms, ” February Naturalist, page 257, line 20, 
read: “All polar conjugations, according to this view, had their 
origin in the original conjugation of one or both polars with the 
second sperm, typically in the second way through triple fusion. 
The polars acquired the property or function of conjugating 
with each other through their common attraction to the second 
sperm. 
Now the question arises as to whether there is a triple fusion 
in Sagittaria and other such cases. Does the second sperm come 
down later and fuse with the first upper endosperm nucleus after 
the partition wall is formed, etc. 
Meeting of the Biological Club. 
Orton Hall, June 1st, 1908. 
The regular monthly meeting of the club was called to order 
by the president, Dr. Geo. D. Hubbard, at 7:40 p. m. The 
minutes of the last meeting were approved as read. 
The first paper of the evening was by Mrs. Alma D. Jackson, 
who spoke on her thesis, “The Genus Lepidocertes.’’ She 
mentioned their relation to other Thysanuran forms, their 
occurrence and size. She also discussed the work done on these 
forms in attempts to discover whether or not these insects 
breathe by trachea. They are very sensitive to killing agents 
of all sorts. The adults moult on an average of every seven or 
eight days. They perspire freely before moulting. The larval 
forms are similar to adults in everv detail. 
The next thesis reported on was by Prof. Durant. His sub¬ 
ject was North American Mallophaga. These are wingless 
insects, chiefly parasitic on birds. Their food consists chiefly of 
hair, feathers or epidermal scales. The Mallophaga are biting
