We hear (says Figaro) a great deal abonfc the wealth of the Silver Kings of Nevada and the Pacific Slope. Ex-Governor Sandford is the richest of them. His yearly income is equal to the interest on 75,000,000d01. The widow of the late Mark Hopkins is worth 30,000,000d01. She, however, does not intend to marry again. A possible matrimonial prize is Miss Jennie Flood. She was engaged to a son of General Grant; but there was an estrangement. She had 2;500,000dol as a present outright from her father, the Bonanza King; and she will inherit ten times as much. Hatlie Crocker, whose engagement to- Lord Beaumont was erroneously announced the other day, is prospectively the richest heiress in the West, She will probably have not less than 25,000,000d01. The wealth of' Mackay, Fair, Bell, Jones and Sherwood has* greatly declined. The have not taken any ore out of their mines on the Comßtock Lode for three years; and the shares they onco held at 500dol, and in one case at 2,500d0l per share of lOOdol. are of no value. The Australasian Medical Gazette says that in few cities of the world do people lose .their teeth at so early an age as in Sydney notwithstanding that in comparison with other great cities the inhabitants aro domesticated and not addicted to excess in eating, though it must be admitted tbafc intemperance m ono form prevails to a very lamentable extent. It is not uncommon for people to arrive ill that colony with tooth perfectly sound, or having only a few slightly decoyed, to discover themselves, in the course of t'Lur or five years, with barely a sound tooth m either jaw. This, cannot bo accounted for in connection with tho prevailing diet or habits of tho people. In tho judgment of the few medical residents of the city who have dovoted any consideration to it, the cause is to be referred to the very small portion of mineral constituents con tamed in the Botany water. Practically, the Sydney people drink rtiin water ; and soft water, as every laundress knows, has ita disadvantages. Thk branch of the Salvation Army i tt South Australia appears to be quite equal to* the parent body m regard to the sensational character of its.announcements.
