■ in the Russhie Wedomosti, of which the following is condensed from the Chemiker ZeiHcng:
The difficulties in manufacturing platinum which have existed till lately have now been almost entirely overcome. Although the platinum utensils exhibited at the last Paris exposition came from foreign, particularly English, workshops, yet the increase in the use of the metal was very evident. In the Moscow exhibition the production of platinum was represented by only two Eussian firms. P. P. Demidow, prince of San Donato, exhibited native platinum aud platinum plate. In 1875 the firm of Kolbe & Lindfors was established in St. Petersburg to manufacture platinum utensils of all kinds, but their ware was not equal to the English. The firm, with fifteen to twenty workmen, produced platinum ware to the amount of 300,000 rubles, which was used principally in Russia. For the last sixty years the production of platinum has been limited to districts of Goroblogodat and Nishni-Tagilsk. Grains of platinum are found in other districts, but the mining of them has been given up entirely. The following is a table of production from 1827 to 1881, inclusive:
It is seen that the production in the last few years has increased markedly on account of greater inquiry for the wares, and the price has risen also. The 5,956 pounds produced in 1881, came largely from Nishni-Tagilsk (2,456 pounds). Kresto Wosdwisheusk produced 886 pounds; Werchotursk 1,508 pounds and 1,04S pounds mixed with gold; aud Bogoslaw 752 pounds. It is expected the production will soon extend to other districts. Until 1877 the production was almost entirely by private parties. In 1861 the government only mined 128 pounds. The proportion in subsequent years is not given.
Imports. The platinum ware sold in this country is principally made from "flat stock," that is, platinum in the form of sheets or thick wire imported from England. Manufactured utensils are occasionally imported from France. The following imports, therefore, represent the total consumption of platinum in this country, for the slight domestic product is exported to England to be refined.
