Asks about Charles Bell’s statement concerning contraction of eye muscles. Asks whether such contraction is related to secretion of tears.

CD’s questions [on expression] are more difficult than he thought and have led him further afield than he expected. If CD is not hurried, he promises less imperfect answers in six weeks. Thanks CD for drawing his attention to a really important question from different points of view.

There is no hurry for information. Delighted that FCD is making experiments.

It was a sincere pleasure to make FCD’s acquaintance.
