progress in philosophy.

For these reasons we read, with some degree of astonishment, a treatise
on this exploded subject, by a philosopher, an eminent physician, a
privy counseller of the then Empress Queen, and a professor in the
university of Vienna. It was long doubted whether the professor was in
earnest, but the world was at length forced to admit, that the great
Antonius de Haen certainly believed in witchcraft, and reckoned the
knowledge of it, in treating a disease, of great importance to a
physician--to the acquisition of which useful knowledge, he dedicated a
great part of his time. In the year 1758, three old women, condemned to
death for witchcraft, were brought by order of the Empress from Croatia
to Vienna, to undergo an examination, with regard to the equity of the
sentence pronounced against them. The question was not whether the crime

application. The author, and the illustrious van Swieten, were appointed
to make the investigation. After reading over the depositions, produced
on the trials with the greatest care, and interrogating the culprits
themselves _most vigorously_ by means of a Croatian interpreter, these
great physicians discovered that the _three old_ women were not witches,
and prevailed with the Empress to send them home in safety. It was this
circumstance that induced de Haen to write on magic.

we shall here furnish our readers with an abstract of its principles and
reasoning, to which we shall subjoin some remarks.

By the crime of magic, the author informs us, he means any improper
communication between men and evil spirits, whether it be called
