Historical profile The woman that inspired Faraday An amateur and an enthusiast, Jane Marcet wrote what was to become one of history’s most important chemistry books.

She achieved informality of explanation by lively dialogue between plausible characters. Mrs B is a rigorous but humane tutor who is not ashamed to admit ignorance. Her two pupils are intelligent and enthusiastic, but while Emily is over-earnest and ebullient, Caroline is slap- happy, both intellectually and manually. Their conversation SCIENCE AND SOCIETY PICTURE LIBRARY, SCIENCE MUSEUM SCIENCE LIBRARY, PICTURE SOCIETY AND SCIENCE sounds convincing for the period, with Mrs B taking examples from everyday experience and Caroline sometimes mocking her tutor and using less-than-ladylike language. Although Mrs B keeps a tight rein on systematic learning, she makes and allows numerous brief digressions, all relevant to chemistry, and some also related to her pupils’ own interests. These introduce the reader to applied chemistry, and to the rapid socio-economic changes probably Davy’s series on General system.

Alexander wrote: ‘when it was all done, we had a most large party’. Amateurish and inspirational So why should a book, so apparently amateurish, be remembered and admired two centuries later? Marcet’s modesty was justified– she had made no original discovery or interpretation. She wrote simply to share her excitement of learning chemistry.

It is perhaps wiser to read about the experiments than to do them because, although Mrs B sometimes exhorts the young not to repeat the more hazardous demonstrations by themselves, a current safety officer might find her unjustifiably relaxed.
