The "Memoirs of an Ex-Palladist" have not at present proceeded further than the translation of Thomas Vaughan into the paradise of Lucifer, but from the "Free and Regenerated Palladium" and from other sources the chief incidents of Miss Vaughan's early life may be collected and summarised briefly. We learn that she is the daughter of an American Protestant of Kentucky and of a French lady, also of that persuasion. She was born in Paris, and a part of her education seems to have been received in that city; her mother died in Kentucky when Diana was in her fourteenth year, and I infer that subsequently to this event she must have lived with her father, who had considerable property in the immediate vicinity of Louisville. When the Sovereign Rite of Palladism was created by Albert Pike, Vaughan became affiliated therewith, and was one of the founders of the Louisville triangle 11 + 7; he presided at the initiation of his daughter as apprentice, according to the Rite of Adoption, in 1883. She was raised to the grade of Companion, and subsequently to that of Mistress, and at the age of 20 years, says Dr Bataille, she crossed the threshold of the Triangles, as the Palladian lodges are termed. Three issues were published of "The Free and Regenerated Palladium," but since the conversion of Miss Vaughan, they have been withdrawn from circulation, except among ecclesiastics of the Roman Church, and up to the present I have failed to obtain copies. For the autobiographical portions of this organ, I am indebted to the notices which have appeared in the _Revue Mensuelle_. They contain an account of two apparitions on the part of the demon Asmodeus, accompanied by phenomena of levitation and fortified by arguments against the theory of hallucination. These early experiences are, however, of minor importance, nor need I again refer to the sensational incidents which accompanied her initiation as Templar-Mistress at the Paris Triangle of Saint-Jacques; but it appears from her memoirs that the intervention of Albert Pike was not in virtue of the supremacy of his personal authority, and that the ordeal of sacrilege was spared her by the clemency of Lucifer himself, who is supposed to appear in person at the Sanctum Regnum of Charleston and to instruct his chiefs, _Deo volente_ or otherwise, every Friday, the supreme dogmatic director, who had made his home in Washington, having the gift of "instantaneous transportation," whensoever he thought fit to be present in the "divine" board-room.
