HUMANARUM, which was to be an appendix to the MAGIA NATURALIS. See DE
AUG. iii. 5. This will appear clearly by comparing the descriptions
of the two.

In the ADVANCEMENT OF LEARNING Bacon tells us that there are two
points of much purpose pertaining to the department of Natural Magic:
the first of which is, "That there be made a calendar resembling an
Inventory of the ESTATE OF MAN, containing ALL THE INVENTIONS, BEING

nearest in degree to that impossibility: to the end that by these
optatives and essentials man's inquiry may be the more awake in
deducing direction of works from the speculation of causes."

The Inventory which was to have been inserted in the 10th chapter of
VALERIUS TERMINUS is thus introduced:--"The plainest method and most
directly pertinent to this intention will be to make distribution of
SCIENCES, ARTS, INVENTIONS, WORKS, and their portions, ACCORDING TO
