* My Troughton’s Seven-feet Transit, to which reference was occasionally 
made in the former Memoir, being, on account of its bulk, ill calculated for a tra- 
velling companion, Mr. Simms was requested to construct me one that should be 
more appropriate ; and as it fully answers the purpose for which it was designed, a 
brief description of it may not prove altogether uninteresting to the travelling 
Astronomer. 
The centre piece of this instrument is spheroidal : the length of the horizontal or 
transverse axis, including the pivots, is 28 inches: on one end of this axis is a circle 
of 9.9 inches diameter, having a ring of silver soldered to its circumference, on 
which the dividing lines are drawn ; the circle is provided with a level and two ver- 
niers ; the scale of the former reading to 10 seconds, the latter to minutes only ; it is 
intended solely as a finder, but will give the apparent altitude of a celestial object ac- 
curate to one minute. The tubes of the telescope are conical, screw into the centre- 
piece, and may be removed from it at pleasure, as may be also the circle from the
