If the level of an ideal rectangular water basin varies sinusoidally with amplitude 2h1and angular frequency ω0the modes of the free oscillations of the basin split into multiplets with spacing ω0: the shape and the height of the peaks are given as functions of the mean levelh0and of the lengthlof the basin and of the amplitude 2h

In their 1954 paper Rhodes and Rowlands calculated demagnetizing energies for uniformly magnetized rectangular prismatic crystals and derived effective demagnetizing factorsNbwith no reference to the internal fields. It is shown that the demagnetizing field at the centre of a cube is preciselyNbIsand that the fields at the centres of rectangular blocks with square cross section lie near to the values ofNbIsandNdIs, whereNdis the demagnetizing factor of the inscribed ellipsoid.

A nuclear multiplate camera has been constructed to observe nuclear processes resulting from the bombardment of rectangular target of some extent with a neutron beam. Twelve Ilford K-Z plates are held in a rigid geometry which allows simul- taneous measurements of nuclear reaction at the angles of 15O, 30 , 45O, 60 , . . . and 1651. In this paper the determination of counting efficiency of the nuclear plate is described. A scheme of a numerical calculation for the counting efficiency is pro- gramed and carried out. AS a check measurements of efficiency are made by counting the number of n-particles on the nuclear plates from PO-210 source electro-plated on the target. The results are in good agreement with the calculated ones.
