Mr. Tennant may be considered as one of those "who, without much labour, have attained a high reputation, and are mentioned with reverence rather for the possession than the exertion of uncommon abilities." * Of such a man it is perhaps impossible to give an account, which will satisfy the judgment of his friends, without being suspected by others of considerable exaggeration. Mr. Tennant is only known to the public by his papers in the Philosophical Transactions, which, however admirable as specimens of his scientific powers, afford a very inadequate idea of the real extent of his genius and knowledge. These were in many respects so extraordinary, that it would be taking a most imperfect view of his intellectual character to consider him only as a man of science. Some attempt therefore ought to be made to do justice to his other distinguished attainments; although a certain degree of caution is obviously requisite in speaking of those qualities, however remarkable, which cannot be duly appreciated except by his particular friends. Smithson Tennant was the only child of the Rev.
