GREENWICH TIME AND ITS TELEGRAPHIC DISTRIBUTION. 365 
Liverpool have likewise made enquiries as to the facilities for 
exhibiting an hourly time-signal on the Tuskar Eock. These 
points, in the English and Irish Channels respectively, are both 
advantageous for such signals ; but some special wire communi- 
cations would in both cases be necessary, so that the first outlay 
might be rather large, otherwise there would be no practical 
difficulty. 
We have now completed our account, which intentionally 
has been confined to the time-operations in connection with the 
Eoyal Observatory at Greenwich. In conclusion we may how- 
ever remark, that the local observatories in Liverpool, Edin- 
burgh, and Glasgow have also for many years done much to 
give authoritative Greenwich time in their respective sur- 
rounding districts. In Glasgow there is a most extensive 
system of controlled public clocks, and Edinburgh and Liver- 
pool both possess time guns.
