Dissolve the strychnin in the warm water; add alcohol to the solution 
until the mixture becomes thin enough to spread easily and to penetrate the 
specimens. The simple aqueous solution is not absorbed readily or spread 
easily, manifesting a tendency to gather in globules like mercury. The 
addition of the alcohol overcomes this difficulty. 
A thorough application of the poison should be made with 
asoft brush to every portion of the surface of each plant. The 
application can be made with the least labor when the moistened 
plants, after being shaped for the herbarium, are about to be 
placed between the driers, As the poison does not penetrate to 
“ny great depth, “moth balls” (napthaline, camphorine, etc.) are 
often placed in the boxes with specimens of very thick and 
bulky fungi, such as species of Fomes and the like, to keep 
away insect visitors. 
My herbarium of fleshy fungi is stored in insect proof tin 
boxes. These boxes (fig. 3) are large enough to take genus cov- 
wa gnd mounting sheets of the full standard size; they are 6™ 
tigh—larger than the usual herbarium pigeonhole, but this is
