02 The Total Solar Eclipse of 1900. 
One of the ccelostats is shown in fig. 1. 
The principal feature of this instrument is that (in view of its possible use on 
future occasions) it is made adjustable to various latitudes, and the clock is so 
mounted on the framework that the adjustment for latitude can be made without 
in any way interfering with, or putting out of adjustment, the necessary gearing 
between the clock and the driving-screw, 
It will be seen by reference to the photograph that the clock-frame is pivoted 
on a bush, which is centrical with the screw-spindle, and is also connected to the 
frame by a series of parallel levers, so that it must in all positions be properly 
geared to the screw-spindle, and also must retain its horizontality for every 
latitude for which the instrument has to be adjusted.
