OBSERVATIONS ON EGG>BLOWING. 165 
that could I devise a machine for the purpose it would be a great 
boon to collectors. 
My first attempt was with a large india-rubber syringe attached 
to a blow-pipe by a tube; but I found that it did not always 
contain sufficient air to empty the egg. I then substituted a 
kitchen-bellows for the syringe, but besides being clumsy it 
frequently broke the egg, from the handle requiring so much 
pressure that it moved the blow-pipe. I then procured a 
cylindrical bellows, shown in the engraving, and find it answers 
admirably, as it works very steadily, and it is easy with this to 
regulate the pressure of the air to the size of the egg.

The blow-pipe (A) is held in a groove by two small buttons, 
so that whilst firmly fixed it can easily be removed for cleaning 
should it get stopped up. Bis the tubing connecting the pipe with 
the bellows (c), which is supplied with air through a hole (p) in 
the wooden stand to which it is fixed. When travelling, the 
space E is fitted with a box for the drills, &c. For greater 
steadiness a block of lead weighing about two pounds is placed 
in the space under the bellows, or the latter can be fixed to the 
table by means of a small clamp. A small wooden stand is used 
as a rest for the left hand while holding the egg. 
On the subject of drilling I should have had no remarks to 
offer had I not learned from Mr. Seebohm that he used a 
carpenter’s spiral drill for eggs, which he fixed in a horizontal 
position. Fig. 2 shows a small appliance which I have adapted 
for this purpose. It is held in a vice, and is fitted with a drill,
