A NEW MAILING CASE. 
HOWARD N. LYON. 
AKE two slips of wood 3 in. x lin. and 1-16 in. thick, in 
the centre of one make a hole a little larger than the cell 
Paste a piece of stiff paper on one side of this slip, covering 
the hole. Lay the slide between the slips and along one side, 
paste a piece of paper, not touching the glass slide however. 
A rubber band holds the package tight, and it may be sent as 
it is or first wrapped in paper. The postage for a single slide is 
one cent. 
If two or more slides are to be sent the modus operandi is 
the same, except that the openings are alternately on opposite 
aides. In this case the middle slips need not be covered.
