A New Classical Laboratory.

For several months men have been at work rebuilding the top room of the mineralogical museum in Boylston Hall for a new laboratory for organic chemistry. The new room will be fireproof and will have all the latest improvements. The desks are tile topped and each one will be fitted with water and with a vacuum pump. There are enough of these to accomodate 32 men comfortably, and a good many more at a stretch. Nine large hoods, heated at the top with steam radiators, are built into the north wall. The eastern end of the room is divided into three compartments, two furnace rooms and a weighing room. This laboratory will be ready for use by next autumn.
