RIKER’S SPECIMEN MOUNT 
Patented April 1st, 1902) 
pOR generations collectors of insects have impaled their specimens on 
pins, necessitating cumbersome and expensive cases and at best not 
being able to prevent disasters from destroying insects and sudden jars. 
The Rikcr Specimen Mount, the outgrowth of necessity, born from dis- 
pair and the wrecks of a collector’s pride and years of wasted toil, gives a 
new impetus to collecting. 
Its Chief Points Are: 
1st. It preserves the speci¬ 
men from destroying insects 
and from sudden jars. 
2nd. It occupies one-quai'- 
ter the cubic space needed for 
a pin collection, and is only 
one-eighth as heavy as a 
wooden case. 
3rd. It permits the exam¬ 
ination and changing of the 
specimens at will. 
4th. Life Histories of 
nearly all species can be 
shown to perfection. 
5th. It can be used for in¬ 
dividual specimens, pairs or 
genera; or, it may be consti¬ 
tuted into a drawer with glass 
top and bottom. A series of 
these drawers fitted inter¬ 
changeably into a cabinet ac¬ 
commodates four times more 
specimens than an equal sized 
pin cabinet at same cost. 
The Specimen Mount is suitable for Butterflies, Beetles, Dragon 
Flies, Grasshoppers, Bees, Fungi, Shells, or thick plants or bulbs too 
large for the Botanical Mount.
