But along with these shadowy lucubrations were treatises of a more uncommon and a more startling character,--discussions on various occult laws of nature, and detailed accounts of analytical experiments. These opened a new, and what seemed to Sir Philip a practical, field of inquiry,--a true border-land between natural science and imaginative speculation. Sir Philip had cultivated philosophical science at the University; he resumed the study, and tested himself the truth of various experiments suggested by Forman. Some, to his surprise, proved successful, some wholly failed. These lucubrations first tempted the writer of the memoir towards the studies in which the remainder of his life had been consumed. But he spoke of the lucubrations themselves as valuable only where suggestive of some truths which Forman had accidentally approached, without being aware of their true nature and importance. They were debased by absurd puerilities, and vitiated by the vain and presumptuous ignorance which characterized the astrology of the middle ages. For these reasons the writer intimated his intention (if he lived to return to England) to destroy Forman's manuscripts, together with sundry other books, and a few commentaries of his own upon studies which had for a while misled him,--all now deposited in the safes of the room in which I sat. After some years passed in the retirement of Derval Court, Sir Philip was seized with the desire to travel, and the taste he had imbibed for occult studies led him towards those Eastern lands in which they took their origin, and still retain their professors.
