Life And Letters Of Maria Edgeworth…
“ Got home to Herschel's while the sun yet shone, and I having the day before begged the favour of him to repeat for Fanny and Lestock the experiments and explanations on polarised light and periodical colours, he had everything ready, and very kindly went over it all again, and afterwards said to Mrs. Herschel, "It is delightful to explain these things to Mrs. Wilson; she can understand anything with the least possible explanation." ”
