THE greatest of Russian chemists, and

one of the most eminent of any nationality, Dmitri Ivanovich Mendeleyev, died in St. Petersburg, on February 2. Mendeleyev was one of the few great scientists who have given Russia the right to rank with the civilized nations of the world. In the estimation of the noted English chemist, Thorpe, Mendeleyev was for Russia what Berzelius was for Sweden, Liebig for Germany, and Dumas for France.

In view of the world influence of Mendeleyev on the development of chemistry, Thorpe's statement is not at all exaggerated. Chemical science owes to Mendeleyev a new conception and philosophy, for before his day chemistry was a collection of facts rather than a clear exposition of the laws concerning the transformation of



Mendeleyev was born on February 7, 1834, at Tobolsk, Siberia, where his father was director of the classical gymnasium. Soon after Mendeleyev's birth his father lost his eyesight, and the care of the large family fell to his mother, a woman of marked ability and energy. She opened a glass factory in Tobolsk, and her young son learned there his first lessons in chem- gases is of a high order.

His "Principles of Chemistry" (1869) the first textbook on chemistry based on the periodic law, is called The periodic system gave philosophy access by Thorpe a system of chemical philosophy. to chemistry, and to Mendeleyev belongs the credit of having made such access possible, an achievement which he owed to his remarkable mental make-up, uniting the abili

The chemists had discovered about sixty ele

ments, whose properties and combination were made the subject of extensive study. They studied the color, odor, taste, solubility, optical properties, and crystal systems of substances, as well as their ability to react upon other substances. No attempt was made to find a systematic numerical expression for the properties noted. Some of the empirical laws which were discovered seemed to have no connection with one another. There was no systematic arrangement of the chemical elements then known, and the conceptions of atomic weights in their rela

tion to one another were rather indefinite. While it was known that such elements as sodium, potassium, rubidium, and cesium had properties in common, as was true likewise of the group of elements including calcium, strontium, and barium, or of the group including phosphorus, arsenic, and silicon,-no one was apparently struck with the great similarity of properties of the elements in each group and the relations of one group to another.

The periodic law as conceived by Mendeleyev may be described briefly in the statement that "the properties of elements are the periodical functions of their atomic weights." Arranging the elements in the order of their atomic weights, we find at certain intervals the repetition of the same properties. The fruitfulness of Mendeleyev's conception was soon demonstrated in chemical investigation. The atomic weights of some of the rarer elements, which had been determined only ap

proximately, were corrected. Furthermore, new elements predicted by Mendeleyev in accord with the periodic law were actually discovered. A few years after Mendeleyev's framing of his system the element gallium was discovered, and its properties were found to agree exactly with those predicted by Mendeleyev. The discovery of the elements scandium, germanium and of others followed that of gallium, and all_found a place in Mendeleyev's system. The great service rendered by the periodic law to chemistry consists, among other things, in its having made possible the discovery of analogies and properties where no one had hitherto suspected them.

Mendeleyev also performed important service in the employ of the Russian Government. In 1893 he was appointed director of the Bureau of Standards, and took a prominent part in the investigation of the Russian oil fields. The Russian press is practically unanimous in its praise of his services to science and to his country. A complete bibliography of his scientific writings, numbering about 150 books, pamphlets and periodical articles, is to be found in the bibliographical dictionary of the University of St. Petersburg.

the federal Parliament. It was he who, when Mr. Chamberlain told the British Australasian newspaper that he would be interested to know Australian opinion on his scheme, cabled to that journal that “the commonwealth government and all the governments of the separate states approve of Mr. Chamberlain's preferential trade proposals. Only the extreme section of the Free-Traders are opposed to them, and an immense majority is assured for the new policy when it is put before the country. Personally, I consider preferential tariffs an indispensable foundation of the empire." It was Mr. Deakin who invited Mr. Chamberlain to "star" in Australia, who took the first definite steps by the preferential trade resolutions which he moved in December, 1904, and who has now passed an act granting a customs preference averaging 10 per cent. upon British goods imported into the commonwealth in British bottoms manned by white crews. The act, which, when the relative scales of duties are considered, may be taken roughly as equivalent to the Canadian preference of 33 1-3 per cent., has been reserved for the royal assent on the ground of its conflicting with existing treaties.
