Armstrong, another poet and physician and not unworthy of either class, for genius and goodness of heart, though he had the weakness of affecting a bluntness of manners, and of swearing, drew his last breath in this street. He is well known as the author of the most elegant didactic poem in the language, — the Art of Preserving Health. The affectations of men of genius are sometimes in direct contradiction to their best qualities, and assumed to avoid a show of pretending what they feel. Armstrong, who had bad health, and was afraid perhaps of being thought effeminate, affected the bully in his prose writings; and he was such a swearer, that the late Mr. Fuseli's indulgence in that infirmity has been attributed to his keeping company with the Doctor when a youth.
