When this is the case someone is liable to get hurt. I have seen part of a large emerywheel go through a twentv-inch brick wall, after bursting,and I can assure the average polisher that he is likely to getinto the hospital, if he does not use due care in handlinghis emery wheels. I have been thus explicit because I 42 THE POLISHING AND PLATING OF METALS.
