Aloha Jane,

I remember seeing something on the U.S. AMS 1:50,000 topo sheets
of Java (ca. 1940s, based on earlier Dutch mapping).  As an
example, see AMS G8090s 1942.G72 sh.36XXXVIIB, if you have this
set in your files.

On the bottom-left corner of each of the maps is a tiny index to
adjacent sheets.  Next to this graphic reads:
    "Meridian of Batavia (is 106deg48'27.79" E. of Greenwich)".

Batavia is the early Dutch name for Djakarta.  I hope this is
what your patron needs to locate those monkey fossils!

Aloha,
Ross
