PATENT POSTAL BOX WITHOUT PACKING. 



BY H. GUAED KNAaGS, M.D., F.L S. 



The chief object of the new postal box is to prevent vibration 

 of the contents, but it also saves much time in packing. It is re- 

 markably simple and inexpensive, and con- 

 sists of a light box B, suspended "a lafagon 

 du cercueil de Mahomet,''' in a larger and 

 stronger box A, by means of two elastic 

 bands, one of which is shown, in the section, 

 at C C. There are numerous variations on 

 the method of suspension according to the articles to be conveyed, 

 but the one here given is most suitable for the postage of entomo- 

 logical specimens. 



The mode of construction was as follows : — having procured a 

 cigar box or any other of light but strong material (preferably metal), 

 I made, with a bradawl, twin holes (as 

 shown at A in the second figure) at 

 A B C D (i.e., front and back of box), 

 and tied on with watercord (as shown 

 at B) two elastic bands, B C and A D, 

 of a substance that will lightly sup- 

 port the weight they have to carry, 

 each half as long as the width of the 

 box, but stretched to the full width in 

 the tying process. N.B. — These knots 

 could be tied on the inside between 

 the bands if neatness be desired, and 

 they should be touched with glue or varnish to prevent subsequent 

 slipping. The distance between the bands should be at least two 

 inches less than the length of the box to be suspended. The inner 

 box should be as light as possible — a seidlitz powder box answers 

 admirably. All that has now to be done is to slip the inner box 

 between the bands, and — voila tout.
