stops at a tumbledown cottage to ask for a glass of milk. Instead he's sold a bottle of the 'elixir of life' by a weirdy beardy who claims to be 'the last of the alchemists'. When the stuff is swigged by an organ-grinder's monkey, the elixir proves to be not that of life but of evolution.
In minutes the monkey has evolved into a hairy hominid, then into a hirsute but respectable man and ends up as the peculiar egg-head you see here - the future of mankind, a giant cerebellum on a puny body. Interesting to see this cliche of science fiction appearing so early. Indeed, the 'future man' reveals another talent that became a staple of sci-fi - his enormous brain grants him telepathic powers and he is able to control the timid student's every movement (that's why he's wearing the ex-monkey's little hat: he was forced to). A rather feeble yarn but an interesting oddity. And I do like the goggle-eyed, tentacle-fingered geezer imagined up by Mr Illingworth - he's like a pink Mekon in a trilby.
