46 RESEARCH IN CHINA. 
The assembling of the various geologic sections for the purpose of corre- 
lating them and their contained faunas led to the construction of fig. 9, 
on page 45, in which each section is assigned its approximate position 
in relation to the other sections and to a theoretically entire section. The 
various finds of fossils are given the same locality number as in the sections 
already described and in the list of localities [pp. 15-27]. 
SECTION IN MANCHURIA. 
The following section was measured by Prof. Joseph P. Iddings on the 
island of Tschang-hsing-tau, Province of Liau-tung, Manchuria. Read from 
the top downward:

Notes on Horizon of Collections. 
Localities 35”, 357, 36¢, 36d, and 36e are very nearly the same horizon, being located above a low bluff, 
10 feet high, with nearly horizontal strata in places slightly folded and faulted. These are the 
lowest beds and not far above the basal. 
Locality 35 is about 80 feet higher up in the shales and limestone. 
Locality 36h is about 50 feet higher than No. 35. 
Localities 36g and 350 are back from the bluff on drainage cuts in shale about the horizon of No. 36h, 
I judge. 
Locality 35q is about 70 feet higher up than No. 36h. 
Locality 36f is the highest from which fossils were collected and is possibly 800 feet higher up than No. 36c.
