He went on to state the cake should be cut in parallel lines, starting in the centre, with the rectangular segments of the cake then taken out and eaten.

'Christmas suggests cakes, and the wish on my part [is] to describe a method of cutting them that I have recently devised to my own amusement and satisfaction.

'The problem to be solved was, "given a round tea-cake of some 5 inches across, and two persons of moderate appetite to eat it, in what way should it be cut so as to leave a minimum of exposed surface to become dry?"

'The ordinary method of cutting out a wedge is very faulty in this respect. The results to be aimed at are so to cut the cake that the remaining portions shall fit together.

'Consequently the chords (or the arcs) of the circumferences of these portions must be equal.

'The direction of the first two vertical planes of section is unimportant; they may be parallel, as in the first figure, or they may enclose a wedge.

'The cuts shown on the figures represent those made with the intention of letting the cake last for three days, each successive operation having removed about one-third of the area of the original disc.
