No. 55.—Six-inch Transit Theodolite and Leveling Instrument 
of superior construction. The cut does not fairly represent the 
instrument, as the level over telescope and the striding level over 
axis are omitted. The horizontal circle is 6| inches in diameter, 
divided on silver, and reads by two verniers to ten seconds; the 
vertical circle is four inches in diameter and reads to thirty seconds.
