There is no doubt that spirit-writing is very ancient, China alone furnishing sufficient evidence of the fact.
The words might have been spirit-writing, they might have meant anything.
I have been reading lately a curious work from an old German in Paris who has been making experiments in spirit-writing.
Then it was held under the table, and in a few seconds covered with ‘spirit-writing.’
On another occasion Mr. William Eglinton proposed to me to try and procure the spirit-writing on his arm.
