Another word for inquirer

Perhaps something depends on the inquirer as well as the scryer.

Sanford of the Inquirer, the principal Unitarian organ.

The scientific inquirer will find a mass of material in the papers and reports contributed to the numerous.

But when the scryers see details of various sorts, which are unknown to the inquirer, but are verified on inquiry, then telepathy perhaps fails to provide an explanation.

He ought not, of course, to be told more than that he is to descry the inquirer's thoughts, and there ought never to be physical contact, as in holding hands, between the inquirer and the scryer during the experiment.
