No. 51.—Repeating Theodolite, as shown on cut, constructed by us 
for the United States Coast Survey, and exhibited in the Govern¬ 
ment Building at Philadelphia. It is of much improved construc¬ 
tion, and exceedingly light and strong. The telescope, having a 
clear aperture of 2 inches by only 12 inches focal length, gives great 
brilliancy to the image. The circle is 10 inches diameter, divided 
on silver, and reads by means of three verniers to five seconds. By
