Dear Sir:

In reply to your communication of the 18th inst. concerning
the illustrative work done for the Survey during the past year in
the Division of Vertebrate Paleontology, I can only give a
general statement, which will perhaps answer your purpose.

1. About sixty lithographic plates have been prepared and printed, mainly for the volume on Sauropoda now nearly completed.

2. About one hundred woodcuts have also been prepared during this period. A few of these were for the volume on Dinocerata already completed, and the remainder for the memoir on Sauropoda.
