ARACHNIDA, MYREOPODA, AND PERIPATUS. 95 
three parts filled with specimens, and the rest of the space at the 
top with pieces of soft crumpled paper or wool wrapped in paper. By 
this means risk of damage from shaking during transit is reduced to 
a minimum. When glass tubes are used, they should be wrapped 
in paper and plugged with cotton-wool. 
If glass tubes are not available, an excellent substitute may be 
made by rolling pieces of stiffish paper into the required size and 
shape and tying them round with cotton or string. 
In the place of glass jars, which have the disadvantage of being 
both heavy and breakable, tobacco or other tins with an inlet tight- 
fitting cover make a satisfactory receptacle for specimens of all 
kinds. The cover should, if possible, be soldered down to prevent 
possibility of leakage, or fixed by means of a bladder. Neither 
sealing-wax nor india-rubber should be used to close a vessel con- 
taining alcohol, since they are acted upon by that fluid. 
If the duration of transit is likely to be short, specimens may be 
packed in wool saturated with spirit. 
Serviceable forceps for purposes of collecting large specimens 
may be improvised by nailing two pieces of lath to a block of wood.
