1. The nuclear division of diatoms occurs not only in the night, as it is generally assumed, but also in the day time, if they are subjected to a certain condition.2. The movementof the nucleus toward the girdle region is one of ther emarkable phenomena in the mitosis.3. The origin of the central spindle is not studie…
The atomic structure of solid solutions of copper-aluminium, aluminium-magnesium, and copper-nickel has been examined by the X-ray spectrometer. In each case it was found that the solute atom replaces an atom in the lattice of the solvent, the substitution being accompanied by a distortion of the lattice. A saturated…

(1923). XXII.—THE PLASTICITY OF COTTON AND OTHER MATERIALS. Journal of the Textile Institute Transactions: Vol. 14, No. 11, pp. T390-T413.
Abstract This paper analyzes the stresses in bent tubes of rectangular cross-section and shows that in the case of thin tubes the distortion due to bending results in greater flexibility and less strength than given by the usual formulas. In an appendix an approximate solution of the problem is obtained by a considera…
fibers will be seriously weakened through the dissolution of the @ pectin or gum that holds together the fiber cells forming the strands -! or commercial fibers.3 Many practical retters assert that the only reliable test for the completion of retting is to remove several handfuls from different parts of the retting ta…

WHILE the physical phenomena in connection with the electrical rupture of gaseous insulators have been thoroughly investigated by J. J. Thomson, J. Stark, J. Townsend, J. B. Whitehead, F. W. Peek, Jr., and many others, the nature of the breakdown in solid and liquid insulating materials has up till now remained in com…
Temperature variation of several physical properties of Rochelle salt, from - 30\ifmmode^\circ\else\textdegree\fi{} to + 30\ifmmode^\circ\else\textdegree\fi{} C., was undertaken to determine which of them seem to be related to the piezo-electric effect, which increases rapidly between - 20 and - 15\ifmmode^\circ\else\…

In centrifuging samples of sea water from Plymouth Sound and some of the stations outside, some interesting forms of Exuviella were found. These are all minute, the largest measuring 22 µ in length, and consequently are easily overlooked, although one at least is abundant during the summer months. This species, which…
