THE YOUNG SCIENTIST. 
away to within an eighth of an inch of 
where the wing joins on to the body of the 
fly as shown at n in the figure. Through 
the piece of paper on which the fly's 
wings were fastened, a long and slender 
pin passed, as shown at e. This pin en- 
tered the apex of the paper cone, f, on 
which it rested. A thin broom splint from 
one and three-quarter inches to two inches 
23 
placed on his legs, which he immediately- 
grasped with his six feet. At times he 
would spin it around with great rapidity,, 
again he would pass forwards and back- 
wards from one end cork to the other, or 
he would hold it in a perpendicular posi- 
tion by one of the end corks. Sometimes , 
he would allow one end of the pole to rest 
on the ground and against the side of the 
PEEFOKMING FLY. 
in length, constituted the balancing pole p 
p. This pole was sharpened to a fine point 
at both ends, so that it might be passed 
into the three small pieces of cork, a b c. 
Now I will try and describe the perform- 
ance. When the fly was placed in posi- 
tion on the apex of the cone, e, as shown 
in the figure, the balancing pole was 
cone, while the other end he retained with 
his feet ; suddenly he would raise the pole 
and spin it around. When releasing the 
fly for exercise, and that he might eleart 
himself or have a sun bath, the pin is 
withdrawn from the paper, or the fly is 
immersed for an instant in water whictt 
soon softens the gum and the fly is free.
