The facilities provided for practical teaching at the Ecole Polytechnique, at the time of its foundation and during the Napoleonic period, have been the subject for much research and conjecture. Documents are discussed and presented which throw light on the actual situation, the number of laboratories, their equipment and apparatus, and the amount of practical instruction provided for the students.

In a letter found not long ago in the Institute of Electrical Engineers and recently republished in the new edition of Faraday's correspondence, certain allegations are made about difficulties experienced by Humphry Davy in getting his work published in Napoleonic France. These allegations have been repeated in the standard Davy bibliography and are believed by at least one other Davy scholar known to the author. A new biography of Faraday makes much of this supposed incident and suggests a comparison with (...) Stalinist Russia. No doubt the letter will continue to be quoted and the story believed until someone takes the trouble to examine the situation more closely. (shrink)
