The use of a 2 per cent. solution is too strong for all grains, even 
with a short application. 
A ¥% per cent. solution is about right for oats, and the treatment may 
be continued for as long as two hours without injury to the seed. 
For wheat a treatment with a 14-per-cent. solution for one-half hour 
is safe, while a 14 per cent. solution for the same time will not decrease 
the germinating power of the seeds to any considerable extent. 
Corn may be treated for two hours with a 1% per cent. solution without 
injury. 
Rye is injured in a 4 per cent. solution for one hour. 
When germination is slightly retarded by the treatment, the plants 
soon equal in their development those of the untreated seeds. 
A List oF THE MycrtozoA CoLLECTED NkAR CRAWFORDSVILLE, INDIANA. By 
KE. W. OLIve. 
The accompanying list comprises forty-three Myxomycetes, thirty-two of 
which are not reported in Dr. Underwood’s ‘ List of Cryptogams of Indiana,” in 
the Proc. Ind. Acad. Sci., 1893, p. 30. 
Duplicates haye been deposited in the herbarium of Prof. M. B, Thomas, 
Wabash College, Crawfordsville, and in the Cryptogamic Herbarium of Harvard 
University. 
The determinations have been made according to the descriptions in the 
Monograph of the Mycetozoa, by A. Lister. 
The collections were made mostly in August, 1897, and with few exceptions 
the species seemed to be comparatively abundant, several gatherings being made 
of many of them. The majority of the species were found upon decaying stumps 
and logs, while a few were fruiting upon living leaves and stems, and still others 
on moss and fallen leaves. 
Two instances were noted of a curious growth of the very abundant Physarum 
cinereum Pers. A circle about six feet in diameter was clearly outlined in both 
cases by the grayish sporangia fruiting upon the living leaves and stems of grass 
and Plantago. The border of the ring was pretty regular and five or six inches 
broad. Here and there within the ring were sinall groups of sporangia, but the 
most were confined to the outer border. he plasmodium had probably been 
feeding upon the dead grass stems lying clove upon the ground, and, as it grew
