50 JOURNAL OF THE ARNOLD ARBORETUM [voL. 55 
Notes: The continuous sequence of roman and arabic page numbers is worth 
being mentioned. The gap in pagination in volume 1 (pp. xiii-xvi are lacking) 
proves that the preliminaries were printed later than the text proper and that 
the original estimate of 16 preliminary pages was not realistic. 
Leaves 14, of vol. 1 and 13, of volume 3, both blank, are present in the NcD- 
MC copy. The pagination, however, indicates that these blank leaves were in- 
tended to be cut out, as was done in the HBL copy. 
The wrong folding of gathering 1 of volume 2 in the NcD-MC copy results in 
the following irregular arrangement: 1, 1, 1, 13; ii-iv i-ii vii viii v vi. 
In volumes 2 and 3 of the HBL copy the part titles for part 1 are inserted 
at the wrong places: 
Vol. 2: 12-14 21-23 11 24; iti—v vi-vii viii-ix x—xiv i-ii 15 16. 
Vol. 3: fe-14 21 11 22-24; ai-v vi-x i-ii 11 12-16. 
This work is considered Bigelow’s most important contribution to medical 
botany. It is outstanding for the mixed intaglio processes used for the prep- 
aration of the copper plates, being a combination of engraving and aquatint 
and sometimes stipple engraving. Of the 60 species figured, four are illustrated 
here for the first time (Gentiana catesbaei Walt., Solidago odora Ait., Statice 
caroliniana Walt. [= Limonium carolinianum (Walt.) Britton] and Polygala 
rubella Willd. [= P. polygama Walt.]).
