Abstract
THE manufacture of the Pyrex disk for the 200-inch reflecting telescope of the California Institute of Technology is one of the most notable technical feats of this decade. A detailed description of the manufacture and annealing has already appeared as a Supplement to NATURE (February 8, 1936), and we have now received from Dr. G. E. Hale the following description of the transportation of the giant disk from Corning, N.Y., to Pasadena, California, where the mirror will be ground, polished and figured.
