35G W. IMBODEN ON A SIMPLE DRAWING AND PROJECTION APPARATUS. 



Many years ago Mr. Nelson recommended an almost identical 

 appliance, which for some reason or other seems never to have 

 been generally adopted. I should feel amply rewarded if my 

 little contribution awakens a new interest in Mr. Nelson's drawing 

 mirror, as it is, without doubt, a most practical and useful little 

 instrument.
