The products of Dr. Herings pen, principally in the form of essays, are scattered among numerous medical journals covering a period of over fifty years.

The titles of these essays and the places where they may be found I have quoted, with the help of Mrs. Hering, after Dr. Herings demise in 1880, so that all who wish to peruse what he has written, may do so by consulting the volumes in the Library of Hahnemann college.

His later literary efforts were concentrated upon his larger medical works. An indexed review of these writings and larger works follows. They are complete in themselves so far as they have appeared, and are available to students and interested readers. They are links which, connected, form the chain of scientific research in which is summed up the experience of Herings life.

In earlier years, when cares were not so thick, nor duties so pressing, he wrote verse and light prose, fairy tales, satires and novelettes. A satirical vein runs through all of these writings, playful in the lighter products of his pen, but extremely biting and severe when in polemics, he felt called upon to defend the cause.
