cetelt the commercial appeal. Germany must needsbuy all of her glass for scientific purposes in Paris orin Manchester, and here was an opportunity ofbuilding up a new industry which would employGerman workmen and bring money into Germany.So the Prussian government appropriated 10,000marks ($2,500) in 1883 and again in 1884 to have theexperiments carried forward. At the end of that timeso successful were the investigators that a regularglass-making establishment was well under way andthere was no further need of government assistance.In four years time these glass works furnished a largeproportion of the fine scientific and optical glass usedin Germany, and now their wares are known every-where in the world,— in the form of microscope andphotographic lenses and prisms, in thermometers, inchemical apparatus, and in the highest grades ofcommercial.glass. This little story is especially in-teresting as showing why Germany is making suchextraordinary strides in commercial affairs. Out of

Pouring Molten Glass into Lens Mould 204 Seen in Germany Science, assisted by the state, has sprung a new andprofitable industry. In all over one hundred new kinds of glass wereoriginated and are now manufactured at the Jenaglass-works. In former times glass was composedalmost entirely of the silicates, potassium, lead, soda,and lime, and there were, roughly speaking, only twovarieties: the old-fashioned standard crown glass andflint glass. Professor Abbe and Dr. Schott used nofewer than twenty-eight new substances in glass-making : phosphorus, borax, magnesium, zinc, cad-mium, bismuth, iron, mercury, antimony, tin, andothers. Each of these substances had its own pecu-liar effect on the refraction and dispersion of light,and in doing away with or lessening what is knownas the secondary spectrum. Much of the glass thusproduced has been ground into lenses at the Carl-Zeiss Works, and the microscopes which resultedgave a new impetus to every department of sciencewhich has to do with minu
