A new process for the production of a textile material is thus described in Industries and Iron: "It consists of 'squirting,' in a fashion similar to that of making electric incandescent carbons, pure gelatin in threads of about one thousandth part of an inch in diameter, the thread being taken away on revolving tapes. The threads are wound upon reels and exposed to formalin vapor, which exercises a most remarkable effect on the gelatin, rendering it insoluble in any medium yet applied to it. The tensile qualities of the thread are also increased, while, in opposition to that produced under the Lehner process (which is simply forming nitrated cellulose into threads for weaving), it is capable of taking up any dye desired; and it is, of course, impervious to any hygroscopic influence."
Prof. E. C. Pickering, of the Harvard College Observatory, announces the discovery by Mrs. Fleming of a new variable star in Sagittarius. It was found on eight of the photographs in her large collection. On March 8, 1898, it was of the fifth magnitude, and on April 29, 1898, of the eighth magnitude. A plate taken on March 9, 1899, shows it still visible and of the tenth magnitude. Its spectrum resembles that of other new stars. The entire number of new stars discovered since 1885 is six, of which five have been found by Mrs. Fleming.
Because of the great loss by fire which occurs every year in the Russian villages, the government is making efforts to induce the peasantry, says the _Saturday Review_, to employ some less dangerous material than straw thatch for the roofing of their _izbas_. There has already been a large increase in the use of shingle, and this has led to a considerable importation from Belgium and Germany, and also from the United States, of simple and inexpensive shingle making machines, for use in rural districts. German manufacturers, whose "commercial intelligence department" is remarkably well informed, are now making redoubled efforts to meet the immense demand anticipated. An improved and inexpensive hand fire engine is also being provided. Roofing felt or paper is very generally used under the shingle, and the demand for this is also increasing.
A fourth specimen of the _Notornis Mantelli_, a bird of New Zealand supposed to have become extinct, was captured in August last, and has been prepared for the museum by Mr. W. B. Benham. The first specimen was obtained, recently slain, by Mr. W. Mantell, in 1849, and is preserved in the British Museum; the second was killed by Maoris in 1851, and is in the Colonial Collection; and the third, now in the Dresden Museum, was taken in 1879. All these birds were found in a single denuded region of the country. The present specimen was caught by a dog in the bushes near Lake Te Anan, still in the same region, and is a very fine young female.
