discoveries, here is a bottle of oil, which I have purified, and rendered
as transparent as spring water. I was offered L10,000. for this discovery;
but I am so neglected, and so conspired against, that I am determined it
and all my other discoveries shall die with me."

I now inquired, whether he had been alarmed by the ignorance of the
people in the country, so as to shut himself up in so unusual a manner.

"No," he replied, "not on their account wholly. They are ignorant and
insolent enough; but it was to protect myself against the governments of
Europe, who are determined to get possession of my secret by force. I
have been," he exclaimed, "twice fired at in one day through that window,
and three times attempted to be poisoned. They believed I had written a
book containing my secrets, and to get possession of this book has been

that it was a mere figure, to deceive the vulgar. He appeared also to
give full credit to the silly story about Dee's assistant, Kelly, finding
some of the powder of projection in the tomb of Roger Bacon at
Glastonbury, by means of which, as was said, Kelly for a length of time
supported himself in princely splendour.

I inquired whether he had discovered the blacker than black of Apollonius
Tyaneus; and this, he assured me, he had effected; it was itself the
powder of projection for producing gold.

Amidst all this delusion and illusion on these subjects, Mr. Kellerman
behaved in other respects with great pr
