Lewis Carroll

“ It is entirely unwholesome. I never ask for it without reluctance: I never take a second spoonful without a feeling of apprehension on the subject of possible nightmare. This naturally brings me to the subject of Mathematics, and of the accommodation provided by the University for carrying on the calculations necessary in that important branch of Science. ”

“ I HAVE a fairy by my side
Which says I must not sleep,
When once in pain I loudly cried
It said "You must not weep."
If, full of mirth, I smile and grin,
It says "You must not laugh;"
When once I wished to drink some gin
It said "You must not quaff."
When once a meal I wished to taste
It said "You must not bite;"
When to the wars I went in haste
It said "You must not fight."
"What may I do?" at length I cried,
Tired of the painful task.
The fairy quietly replied,
And said "You must not ask."
Moral: "You mustn't." ”

“ Again, it is often impossible for students to carry on accurate mathematical calculations in close contiguity to one another, owing to their mutual interference, and a tendency to general conversation: consequently these processes require different rooms in which irrepressible conversationalists, who are found to occur in every branch of Society, might be carefully and permanently fixed. ”
