ATT 1: Sherlock Holmes—his limits.

- Philosophy.—Nil.
- Astronomy.—Nil.
- Politics.—Feeble.
- Botany.—Variable. Well up in belladonna, opium, and poisons generally. Knows nothing of practical gardening.
- Geology.—Practical, but limited. Tells at a glance different soils from each other. After walks has shown me splashes upon his trousers, and told me by their colour and consistence in what part of London he had received them.
- Chemistry.—Profound.
- Anatomy.—Accurate, but unsystematic.
- Sensational Literature.—Immense. He appears to know every detail of every horror perpetrated in the century.
- Plays the violin well.
- Is an expert singlestick player, boxer, and swordsman.
