Bureau of Standards speeds up photomicrography with new apparatus. Washington, D.C., Aug. 18. By means of this new apparatus just designed by the metallurgical divisions of the National Bureau of Standards, it is now possible to make 700 micrographs per working day of the structural effect of corrosion on cross sections of metallic specimans. This new machine uses roll film of 900 negatives at one loading, thus dispensing with the repeated loading and unloading of individual film holders by which method the Bureau was only formerly able to make 12 micrographs per working day.
