Who were Day and Martin? Give a short sketch of their lives,
and state their reasons for advertising their blacking on the
Pyramids. Do you approve of the advertising system in general?
3. Do you consider the Japanese the original inventors of blacking?
State the principal ingredients of blacking, and give a chemical
analysis of the following substances: Sulphate of zinc, nitrate of
silver, potassium, copperas and corrosive sublimate.
4. Is blacking an effective remedy against hydrophobia? Against
cholera? Against lock-jaw? And do you consider it as valuable an
instrument as burnt corks in playing tricks upon a drunken man?
This was the Master's paper. The Mathematical Lecturer next gave
him a few questions, of which the most important were:-
II
1. Prove that the shoe may be represented by an equation of the
fifth degree. Find the equation to a man blacking a shoe: (1) in
rectangular co-ordinates; (2) in polar co-ordinates.
2. A had 500 shoes to black every day, but being unwell for two
days he had to hire a substitute, and paid him a third of the wages
per shoe which he himself received. Had A been ill two days longer
there would have been the devil to pay; as it was he actually paid
the sum of the geometrical series found by taking the first n
letters of the substitute's name.
