**The Singular Materialism of a Progressive Thinker**
**MORE THAN JUSTIFIED BY THE EXPERIMENTS OF THE CELEBRATED PROFESSOR DUMMKOP_F BOSTON, MASS.**
BOSTON, December 13—Professor Dummkopf, a German gentleman of education an_ngenuity, at present residing in this city, is engaged on experiments which,
if successful, will work a great change both in metaphysical science and i_he practical relationships of life.
The professor is firm in the conviction that modern science has narrowed dow_o almost nothing the border territory between the material and th_mmaterial. It may be some time, he admits, before any man shall be able t_oint his finger and say with authority, "Here mind begins; here matter ends."
It may be found that the boundary line between mina and matter is as purel_maginary as the equator that divides the northern from the souther_emisphere. It may be found that mind is essentially objective as is matter,
or that matter is as entirely Subjective as is mind. It may be that there i_o matter except as conditioned in mind. It may be that there is no min_xcept as conditioned in matter. Professor Dummkopf's views upon this broa_opic are interesting, although somewhat bewildering. I can cordiall_ecommend the great work in nine volumes, Koerperliehegelswissenschaft, to an_eader who may be inclined to follow up the subject. The work can undoubtedl_e obtained in the original Leipzig edition through any responsible importe_f foreign books.
Great as is the problem suggested above, Professor Dummkopf has no doub_hatever that it will be solved, and at no distant day. He himself has taken _asterly stride toward a solution by the brilliant series of experiments I a_bout to describe. He not only believes with Tyndall that matter contains th_romise and potency of all life, but he believes that every force, physical,
intellectual, and moral, may be resolved into matter, formulated in terms o_atter, and analyzed into its constituent forms of matter; that motion i_atter, mind is matter, law is matter, and even that abstract relations o_athematical abstractions are purely material.
