INSTRUCTIONS FOR COLLECTING 



three parts filled with specimens, and the rest of the space at the 

 top with pieces of soft ci'umpled 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 stitiish 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.
