medica. They are enumerated under three heads and several: 
subdivisions, viz. : 
I, History of Chinese Materia medica. Review of 42 Chinese 
standard works of this class (already dealt with in the first chapter 
of these notes). 
II. Medical Treatises. 
a. Titles of 84 works quoted in the ancient Pen ts‘ao (or 
Treatises on Materia medica) previous to Li Shi chen. 
b. Additional list of 276 works first quoted by Li Shi chen. 
IIT. Classical, historical, geographical, philosophical and other 
works. 
a. Titles of 150 works quoted in the ancient Pen ts‘ao. 
b. Additional list of 440 works first quoted by Li Shi chen. 
Under the second and third heads are comprised dry lists, 
arranged in no intelligible order, without any indication of period, 
giving nothing but the name of the author together with the title 
of the book. Sometimes the author’s name is omitted. As there 
is no break between the name of the author and that of the work, 
it is in many cases difficult, even for a Chinese scholar, to separate 
them, or to decide whether the name of a book or an author is 
meant. There is no doubt that a large number of the works 
quoted in the Pen ts‘ao kang mu were already lost when it was 
compiled, and that Li Shi chen’s quotations were merely taken 
from previous works on Materia medica, especially, as he himself 
intimates, from the Pen ts‘ao compiled in the 12th century by 
T‘ang Shen wei. (See above Hist. Chin. Mat. med. No. 26.) 
As regards the sources of my information on Chinese Biblio- 
graphy, I would in the first place mention A. Wylie’s admirable 
Notes on Chinese Literature, which without doubt occupies one of 
the most prominent places among European scientific publications 
on China, It is a matter of regret that the eminent author has 
generally confined himself in his investigations to such works as 
he knew from actual examination. Thus the greater part of the 
works and authors met with in the Pen ts‘ao do not appearin Wylie’s 
book. Besides this some biographical notices referring to Chinese 
authors have occasionally been derived from the late W. F. Mayers’ _ 
Well-known Chinese Reader's Manual. But for the bulk of Chinese
