EDITORS HARVARD HERALD: Can not some better method of ventilating the chemical laboratory be found than the one now in use? The air is so vitiated with the numerous smells peculiar to a laboratory that it is almost impossible to breathe in the room. If any one raises a window he always interferes with the lamp of the man next to the window. It seems as if some way could be found by which this terrible nuisance could be abated to a great extent. As it is, seventy-five men have to suffer for fear one man's lamp will be blown out.
