TREW (Christopher James), a physician and naturalist, 
was born at Lauffen, in Franconia, in 1695, and settled at

“ Naturae Curiosorum.’’ He also contributed much towards 
establishing a society under the title of “ Commercium Litte- 
rarium Noricum ad Rei Medicse et Scientiae Naturalis Incre- 
mentum institutum,” which published its memoirs. To these 
societies he communicated several papers, and he also pub¬ 
lished several splendid works on anatomy and botany. 
Among others, we may enumerate the following: “ De 
Diflerentiis quibusdam inter Hominem natum et nascendum 
iutercedentibus,” 1736, 4to.; “ Epistola ad Alb. Hallerum 
de Vasis Linguae salivalibus et sanguiferis,” 1734, 4to.; 
“ Tabulae Osteologicae Corporis Humani,” fol, max. with 
coloured plates, 1767. In 1750 he commenced his publication 
of one of the most splendid of the imitations of Flora, under 
the title of “ I'lantae selectas, quarum Imagines pinxit G. 
Dionysius Ehret.” To the incomparable designs of Ehret, 
Trew added descriptions and remarks; and the work ap¬ 
peared in decades, seven of which were completed. In the 
same year he began a similar publication of garden flowers, 
intitle'd “ Amoenissimae Florum Imagines,” which was car¬ 
ried on to six decades. He also published an improved 
edition of Blackwell’s Herbal, in English and German, with 
an addition of some plants. Being in possession of Gesner’s 
wooden plates, he gave an impression of 216 figures of plants 
from them, infilled “ leones posthumae Gesnerianae,” 1748.
