✦ Synopsis

DE BOLLEMONT. (Comptes Rend., clii, 758.)--If copper and platinum electrodes, separated by mica, are heated, a deposit of copper oxide is found on the platinum. Its contour is similar to that of the copper, so that the particles are projected across. The amount of deposit reaches a maximum in a time ranging from 30 minutes at 400 ° C. or above to 3o seconds at 90o ° C. Thereafter the deposit continually disappears. The distance between the electrodes must be under 3 mm. ; within this limit the smaller the distance the greater the deposit. The condition of the surfaces has considerable effect on the results.
