Σελίδα 621 - Mr. Mitchell's two books form unquestionably the best guide to all the mechanical part of architecture which any student can obtain at the present moment. In fact, so far as it is possible for any one to compile a satisfactory treatise on building construction, Mr. Mitchell has performed the task as well as it can be performed.
Σελίδα 1 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
