It may be said that Jenner’s was a poor sort of training for a medical man, but it is to be questioned if he lost much by his ignorance; for a century ago medical knowledge was largely absurdity, and practice mischief; and he did best who stood most frequently helpless in the presence of Nature. Sir Benjamin Brodie relates how he served when a young man with a general practitioner near Leicester Square--
His treatment of disease seemed to be very simple. He had in his shop five large bottles, which were labelled _Mistura Salina_, _Mistura Cathartica_, _Mistura Astringens_, _Mistura Cinchonæ_, and another, of which I forget the name, but it was some kind of white emulsion for coughs; and it seemed to me that out of these five bottles he prescribed for two-thirds of his patients. I do not, however, set this down to his discredit; for I have observed that while young members of the medical profession generally deal in a great variety of remedies, they commonly discard the greater number of them as they grow older, until at last their treatment of diseases becomes almost as simple as that of my Æsculapius of Little Newport Street.[85]
Hunter’s name is often used as a sort of consecration of Jenner, but for no obvious reason. Hunter confirmed, if he did not beget in Jenner a strong liking for natural history; and when Jenner was settled in the country, he often availed himself of his services as observer and collector, writing to him for information about the habits of the cuckoo, the breeding of toads and frogs, and the sexes of eels; for cuckoos’ stomachs, crows and magpies’ nests, for bats, hedgehogs, blackbirds, lizards, hares, and fossils; for a cock salmon, for salmon spawn and fry, for a large porpoise, “for love or money;” for the arm of a certain patient when he dies; suggesting horrible experiments on hedgehogs, bats, and dogs, and describing one of special atrocity upon an ass. The most serious proposition in their correspondence was that Jenner should come to London as a teacher of natural history, but Hunter threw out the suggestion with hesitation, the qualification for the appointment being 1000 guineas down. Jenner had improved, or supposed he had improved, the preparation of tartar emetic, and Hunter wrote--
