A famed English explorer was invited to Dartmouth to tell of his adventures in the African jungle.
"Can you imagine, a people so primitive that they love to eat the embryo of certain birds, and slices from the belly of certain animals? And grind up grass seed, make it into paste, burn it over a fire, then smear it with a greasy mess they extract from the mammary fluid of certain other animals?"
When the students looked startled by such barbarism, the explorer added softly, "What I've been describing, of course, is a breakfast of bacon and eggs and buttered toast."

Christian Konrad Sprengel

Born 22 Sep 1750; died 7 Apr 1816 at age 65. German botanist and teacher whose studies of sex in plants led him to a general theory of fertilization which, basically, is accepted today. Although director of a school at Spandau and tutor in Berlin, he devoted himself chiefly to the study of flowering plants. Sprengel's 1793 treatise [illustration at left] on floral structure examines the ways that flower colors, scents, shapes, and markings work harmoniously to attract insects for pollination. A clergyman and botanist, he spent his life researching the role played by the wind and insects in the fertilization of flowers. Although Sprengel's work was neglected by his contemporaries, Charles Darwin later praised Sprengel's work and brought it brought to public attention.
