Do you know the Society for the Advancement of Science convenes in this City on the 17th inst. to remain in session several days? Should not Christian Science be represented (in the department of "Anthropology," perhaps)? Should you not be a delegate. Western R.R. rates are surprisingly low now, on account of the "R.R. war." Now let our Society appoint you a delegate, and you and Dr. Eddy come, if possible.
