This is an abstract of a paper which Babbage submitted to the Geological Society and which was read before the December 14, 1836 meeting of that Society. This paper represents Babbage's diverse interests, other than those connected with the construction of the analytical engine. In it, Babbage describes an investigation into the source of many impressions left in the channel of a stream and considered by the country people to have been made by horses' hoofs.
