ARMSTRONG. forces then going to the Weft Indies. The " Art of pre- " ferving Health," his beft performance, which was publifhed in 1744, and which will tranfmit his name to potterity as one of the firft Englifh writers, has been honoured with the follo'Aing teftimony of a refpe&able critic : " To defcribe fo
- difficult a thing, gracefully and poetically, as the effects of
- a diftemper on the human body, was referved for Dr.
- ' Armftrong, who accordingly hath nobly executed it at the
- end of the third book of his Art of preferring Health,
" where he hath given us that pathetic account of the fweat- " ing ficknefs. There is a claflical corredtnefs and clofe- " nefs of ftyle in this poem that are truly admirable, and the <c fubjeft is raifed and adorned by numberlefs poetical
- ' images [A]." In ij.,6 Dr. Armftrong was appointed one
of the phyficians to the Hofpital for Lame and Sick Soldiers, behind Buckingham Houfe. In 1751 he publifhed his poem " on Benevolence," in folio; and in 1753, " Tafte, an " Epiftle to a young Critic." In this year an elegant ode was addrefied to him by Dr. Theobald. In 1758 appeared " Sketches, or Eflas on various fubjets, by Launcelot ct Temple, efq; in two parts." In this production above- mentioned, which poflefies much humour and knowledge of the world, and which had a remarkably rapid fale, he is fup- pofed to have been aflifted by Mr. Wilkes. In 1760 he had the honour of being appointed phyfician to the army in Ger- many ; where, in 1761, he wrote a poem called *' Day, an " Epiftle to John Wilke?, of Aylefbury, efq." In this poem, which is not collected in his works, he wantonly ha- zarded a reflection en Churchill, which drew on him the ferpent-toothed vengeance of that fevereft of fatirifts. It may be here cbferved, that nothing appears fo fatal to the intercourfe of friends as attentions to politics. The cordiality which had fubfifted between Dr. Armftrong and Mr. Wilkes was certainly interrupted, if not diflblved, by thefe means. In 1770 Dr. Armftrong publifhed a collection of " Mifctl-
- c lanies" in two volumes; containing, i. " The Art of pre-
" ferving Health ;" 2. " Of Benevolence, an Epiftle to
- ' Eumcnes " 3. " Tafte, an Epiftle to a young Critic,
