Mr. Seeta Nath Ghose says, in his interesting paper on “Medical Magnetism,” that Mandulies (metallic cells) are worn to great advantage in India on diseased parts of the body.  The curative properties of these cells I have seen verified in authentic instances.  When, years ago (I believe about 1852), cholera was devastating some parts of Europe, it was remarked at Munich (Bavaria) that among the thousands of its victims there was not a single coppersmith.  Hence, it was recommended by the medical authorities of that town to wear disks of thin copperplate (of about 2 1/2 inch diameter) on a string, on the pit of the stomach, and they proved to be a powerful preventive of cholera.  Again, in 1867, cholera visited Odessa.

I and my whole family wore these copper disks; and while all around there were numerous cases of cholera and dysentery, not one of us was attacked.  I propose that serious experiments should be made in this direction, and specially in those countries which are periodically devastated by that disease:  as India, for instance.  It is my conviction that one disk of copper on the stomach, and another of zinc on the spine, opposite the former, will be of still better service, the more so if the disks are joined by a thin copper chain.

In the first place it is necessary to say that the rules laid down by Garga, Markandeya and others on the above subject, refer to the inhabitants of the plains only, and not to dwellers on mountains.  The rule is that on retiring a man should first lie on his right side for the period of sixteen breathings, then turn on his left for double that time, and after that he can sleep in any position.  Further, that a man must not sleep on the ground, on silken or woollen cloth, under a solitary tree, where cross-roads meet, on mountains, or on the sky (whatever that may mean).  Nor is he to sleep with damp clothes, wet feet, or in a naked state; and, unless an initiate, should not sleep on Kusha grass or its varieties.  There are many more such rules.  I may here notice that in Sanskrit the right hand or side and south are signified by the same term.  So also the front and north have one and the same name.  The sun is the great and chief source of life and magnetism in the solar system.

Hence to the world the east is positive as the source of light and magnetism.  For the same reason, to the northern hemisphere the south (the equator and not the north) is positive.  Under the laws of dynamics the resultant of these two forces will be a current in the directed from S.E. to N.W.  This, I think, is one of the real causes of the prevailing south-east wind.  At any rate, I do not think the north pole to be positive, as there would be no snow there in such a case.  The aurora cannot take place at the source of the currents, but at their close.  Hence the source must be towards the equator or south.  The course of life, civilization,
