Unlike the preceding one, this problem is quite easy, and no doubt many
hundreds of our readers will have found the correct solution. In order
to obtain this it is only necessary to take the last triangle and paste
upon its three sides the three other triangles, so as to complete the
cat, the dog, and the cock, at the same time producing one large
triangle composed of four small ones. The three summits of these
triangles are then brought together, thus forming a pyramid. The
menagerie, with the swan, the eagle, and the rabbit complete, will then
be found to have been reconstructed.
