Abstract
Charles Babbage'sReflections on the Decline of Science in England… is very well known to historians of science who are aware of its role in the movement to found the British Association for the Advancement of Science and to reform the Royal Society. The work is probably responsible, in large measure, for the assumption that science in Great Britain was in a marked decline in the early decades of the last century, an assumption rarely subject to exact analysis although fairly widely held. Not as widely known is a reply to Babbage written by Gerard Moll of Utrecht and presented to the English reading public by Faraday, one of the men attacked in Babbage's volume. To the best of my knowledge, Babbage's only published rejoinder to Moll appeared in 1851, dismissing Moll and other critics as not having challenged his facts.
