If I were to be painted in oils, shellacked, and framed, I would be posed in my chemical laboratory and nowhere else. Hemmed in by beakers, bell jars, and Erlenmeyer flasks, I would be glancing up impatiently from my microscope in much the same way as my late great-uncle Tarquin de Luce is doing in his portrait, which still hangs in the picture gallery at Buckshaw. Like Uncle Tar, I would be visibly annoyed.
