Rh for a third time to geology while looking over some books which he thought might be useful to his pupils, when he found one published by the brothers Chambers, which contained a chapter on that science. This was not much, but it was enough to inform him how much had already been done in geology, and, perhaps, to give him a hint of some of the possibilities that lay in it. From this time on, he was ardently interested in geology. The journal of his first visit to Loudon and the British Museum, in 1843, attests how he was becoming absorbed in it. He spent his holidays in geological explorations and in excursions which gradually grew larger, until his position as a geologist was recognized, and he became an authority respecting all points and phenomena which had come under his personal knowledge. A hint dropped to him by Professor Jameson as he was about to visit the Isle of Arran taught him to make his notes of observations on the spot, and greatly helped, his daughter Hester observes in the biography on which we have drawn very largely, "to form those habits of extreme accuracy which characterized all his scientific work."

In 1837 Mr. Pengelly assisted in the reorganization of the Torquay Mechanics' Institute, with which he maintained a connection for more than twenty years, and before which he delivered many lectures. In 1844 he participated in the organization of the Torquay Natural History Society, of which he became, in 1851, honorary secretary, and remained so for more than thirty-nine years, "Under his guidance it became a scientific power in the country. Year after year he lectured there, tincturing the locality with his own enthusiasm; and from the society there ultimately sprang the museum in Babbacombe Road, with its admirable collections."

His lectures, delivered gratuitously at Torquay, were very popular, and were attended by large audiences. The fame of them spread, and he was called to other places—Exeter, Exmouth, and larger towns and farther off, and to the great learned societies—where he lectured, always with success, and to the satisfaction and delight of his audiences. "Those persons living, and they are many," says Mr. F. S. Ellis in the preface to Hester Pengelly's biography of her father, "who had the good fortune to hear Pengelly lecture will bear ready witness to the complete mastery he always had of his subject, and of the faculty of imparting his knowledge. Even when speaking upon abstruse subjects to a mixed audience, he would make the matter perfectly clear without in any degree appearing to talk down to the capacity of those he was addressing.… His manner was no less pleasing and attractive than the language in which he clothed his ideas was grateful to the ear." Geology and astronomy furnished the subjects of the lectures.

It would be impracticable in a brief sketch to follow the detail
