In 1832 Edmonds sent papers 'On Meteors observed in Cornwall' and 'On the Ancient Church discovered in Perranzabuloe' to the Literary Gazette and the London and Edinburgh Philosophical Magazine, and subsequently from time to time he contributed to these journals on antiquarian and geological subjects.
He became a diligent inquirer after the evidences of Phœnician commerce, of Roman rule, and Celtic possession in the western peninsula of Cornwall.
He collected accounts of analogous phenomena on the Cornish coast, and in subsequent years several examples of similar alternate ebbings and flowings of the sea were recorded by Edmonds and others, and rather hastily attributed by him to submarine earthquakes.
He had never received any scientific training, and failed to attribute the oscillations to their true cause, the formation of a vast tide wave in mid ocean, probably due to astronomical influences.
[1] He wrote about twelve papers on the Celtic remains of Cornwall, upon Roman antiquities, and ancient customs.
