Egg-drills and blowpipes of various sizes can be obtained at 
almost any naturalist’s shop. 
When the egg is blown and dry, the name of the species, 
locality where taken, and date of taking should be written on the 
shell above and below the hole, also the number of eggs in the clutch 
should be indicated, and each cjutch distinguished by a letter 
(fig. 6). If the eggs are too small and delicate to be written on 
with safety, they should be numbered, and full data written on 
& paper packed with them and bearing a corresponding number. 
The name, or at least the initials, of the collector should also be added.
