Richard Reily, xyii.hy Mr, Rand, F. 
M r. Martyn in this Work has had the Plants, of 
their natural Bignefs, exadly defigned after the 
Life, and with great Accuracy and Succefs printed in 
their proper Colours. This curious Invention was never 
more aptly applied, though I think this is the firfl time 
it has been ufed in Botany, By this Means, without 
a long tedious Defcription, a Plant may be known by 
meer Infpedion. However, that nothing may be want- 
ing, the Author has thought fit to give fhort Defcrip- 
tions, infilling more particularly on thofe minute Parts 
which cannot be fo clearly exprelTed by Sculpture 3 and 
has added, where they could be obtain’d, fome Account 
of their Ufes, 
The Plant in the firfl Table he calls Jalapa Offici* 
narum. 
The Jalap Root has been in common Ufe above 
a hundred Years ; yet the Plant it felf wholly unknown 
to us in Europe till P. Plumier and M. Lignon^ who 
had both pafied a conliderable Time in America in 
Botanical Difquifitions, at their Return, feverally alfur* 
ed Mr. fourneforty that it was a Species of the Plant 
commonly known by the Name of Marvel of Peru ; 
who thereupon thought fit to make Jalapa the Name 
of the Genus, and diflinguifh that of the Shops by the 
Seeds being more rugofe than thofe of the common.
