In a letter to his sister Martha four years earlier, however, Whewell went so far as to suggest that we would not have been created with “the imagination, the fancy, the taste,” if it were our duty “not to exercise them”—suggesting that even the enjoyment of champagne and turtle was a way of carrying out our duties to God!

   In a notebook entry on August 23, 1838, Darwin recorded that he was told this by “Jones.” The editors of the Darwin notebooks claim that “Jones” cannot be identified, but the comment refers to other men who were at Cambridge at the same time as Richard Jones—D’Arbly and Peacock—and this is consistent with my identification of Richard Jones. See Notebook M, p. 99, in Barrett et al., eds.,

   It is now believed that Clement purposely drew out the job in order to increase his bills. Engineers studying the surviving pieces have found that even noncritical parts such as spacing pillars were needlessly manufactured to the same high standards as the operationally essential parts such as figure wheels and gear shafts.

   Vaucanson’s invention was not widely adopted by the French silk weavers, in part because of worries that it would put the skilled weavers out of work. But by the time of Jacquard’s loom, the silk weavers in Lyon had realized that their livelihood was in danger of being overtaken by a new rival, the English silk-weaving industry, and so they accepted the new technology.

   Darwin later dated these entries in his “Red Notebook” “about March 1837,” but Darwin scholars now more specifically think they were from the second half of the month. See Red Notebook, and Sandra Herbert, “Red Notebook Introduction” p. 19, in Barrett et al., eds.,

   At least this was the official version of the story until 2008, when it was discovered that a photogram thought to have been one of Talbot’s early efforts may actually have been a surviving “solar picture” of Wedgwood (see Kennedy, “An Image Is a Mystery for Photo Detectives”). No results of tests have been released, however, and critics wonder if the auction house and Larry Schaaf, the historian who made the claim, were leaping too fast to their conclusions.
