The above is the title of a book just published by J. N Chandler, Adrian, Mich. A very small book it is, but it may be all the better for that. Mr. Chandler holds that "there are two causes, primary and secondary. The primary cause is the weakening and refining processes which have been (ignorantly) carried on ever since the Potato has been cultivated. The secondary cause is, - the inferior position of the electric fluids, which is in the lower stratum of the atmosphere, (especially when the negative state is existing,) permeates everything upon the surface of the earth." The second cause Mr. C. credits to the writings of A. J. Davis, in which the prevalence of cholera is attributed to the electrical condition of the atmosphere. He says where iron abounds, as at Pittsburg, the Potato is free from rot, and the cholera has never raged.

We consider all that is said about electricity as pure speculation; but we find some remarks on the culture and keeping of the Potato, worthy of attention. Mr. 0. endeavors to show, that high culture, and keeping the seed a great portion of the year out of the ground, has brought about a detriment that predisposes the tubers to diseases, as people under certain conditions are predisposed to cholera. This may be; but in Ireland, where the disease has been most destructive, the Potato is seldom housed as in this country, but kept in heaps or pits, out doors.
