1 been still further extended, in order to enable mo to arrive at
2 results which might have been more prolific of benefit to suffering
3 humanity. For instance, 1. Iiegan, during the decrease of the
4 cholera, namely, during the last three weeks, to try the effect of
5 gal vji no-electric rings ns a preventable. I caused a few hun¬
6 dred., to be made, some of copper and zinc, and others of silver
7 and zinc, which I distributed gratis, and observed that whilst
8 some of those who wore the rings of copper and zinc fell victims
9 to the disease, those who wore the silver and zinc rings were all
10 saved. I. is true, that some of the latter became infected with
11 the disease, but the attacks were of so slight a nature that, in my
12 opinion, they would have recovered without any medical assist¬
13 ance. But I must repeat, that this was only at the time when
14 the disease was already on the'decline; and since that period, I
15 have had no other opportunity of making further observations
16 in that country ; consequently, I cannot assert that this pre¬
17 ventative is infallible. However, to ascertain still further the
18 value of these rings for the purpose indicated, I ordered some
19 hundreds of them to be made during my stay at Vienna, in the
20 autumn of 1S-50, at the period when that Asiatic guest took up
21 its residence in that capital. I presented them gratuitously to
22 many persons, and I have, not heard of a single fatal attack
23 attending the wearers. Many medical men and others expressed
24 their opinions upon the subject, and thought the idea a ridiculous
25 one; but the future will show whether I am mistaken or other¬
26 wise. Some of the wearers of these rings at Lahore stated that
27 they diffused warmth in the finger on which they were worn,
28 in fact I observed a sort of rash to break out on the part
29 on which they wort the rings, and they were obliged to dis¬
30 continue wearing them for a few days, or place them on tin
31 other hand. One ring is quite sufficient for one person, although
32 the wearing of several would do no harm. Bracelets, buckles,
33 and chains produce still greater effects, and I am of opinion
34 that such ring's, &c. are not only useful during the cholera,
35 but are beneficial in many other respects. I have myself enjoyed
36 the best of health during the last six years, which I attribute
