avoided; and the absurdity of the notion in the opinion of the other 
members of the class did not in the least oie her positive assertion 
of its poisonous qualities. It would be a curious and, withal, an inter- 
esting inquiry to trace upand catalogue such experiences and to investi- 
gate the nature of the poisoning, if such it be. The subject has consider- 
ns of the indefiniteness and evasiveness of the ghost, haunted-house 
mesmeric questions now being investigated by the society for psy 
chiéal research, and it may be doubted by some if the results of the in- 
quiry would be any more valuable.. There is, however, the substantial 
question of rhus poisoning, whose etiology has not yet been settled, to 
afford a point de résistance, and when that is fully elucidated the more 
obscure cases may, to some extent, fall easily into place. Even a knowl- 
edge of the extent of the subject would have a value.
