I have tried the new Electric Pen for writing MS, printing and drawing, and consider it perfectly successful for all three purposes. For simplicity, expedition, and cleanliness in working, it seems to me to be quite unrivalled, and those who, like myself, often require twenty or thirty copies of a paper of questions or formulæ, &c., will save the cost of the machine in printer’s bill several times over in a year.
