A micro-mushroom, a parasite that kills a white worm, enemy of the
beet, has been artificially cultivated. As soon as the worm is
attacked, the ravage continues until the entire body of the insect is
one mass of micro-organisms. Spores during this period are constantly
formed. If it were possible to spread this disease in districts
infected by the white worm, great service could be rendered to beet
cultivation.
In sugar refining it is frequently desirable to determine the
viscosity of sirups, molasses, etc. Methods founded upon the rapidity
of flow through an orifice of a known size are not mathematical in
their results. A very simple plan, more accurate than any hitherto
thought of, is attracting some attention. Sensitive scales and a
thermometer suspended in a glass tube are all the apparatus necessary.
The exact weight of thermometer, with tube, is determined; they are
immersed in water and weighed for the second time; the difference in
weight before and afterward gives the weight of adhering water.
