The difference from Greenwich mean time of each of the above average 
meridians, is— 
hours. min sec. 
1. Mean longitude ids ia 99: DA 
2. Longitude of mean area .. 11.80 3847 
3. Average longitude of ports ... 11 382 569 
The object being to establish one time for the whole colony, the adoption 
of which will cause the least inconvenience, the author recommended that 
the meridian of 172° 30’ east be taken, for the following reasons :— 
ist. It is a close approximation to the average longitude for the colony. 
2nd. The absolute longitude of any place in the colony has not yet been 
determined ; and it is therefore better for a statute to adopt a meridian as 
basis, than an approximate longitude for a place which might hereafter 
require rectification. 
8rd. Longitude 172° 30’ east is 11h. 80m. east of Greenwich ; and being . 
an even number, will be most suitable for the purpose of enabling mariners 
to compare the errors of their chronometers on mean Greenwich time; while 
the adoption of the mean time of place for any town or port in the colony 
will have no practical advantages. 
The following table shows the correction required to reduce the time for 
meridian 172° 30' to the mean time at the various ports; and the correction 
for any other place can at once be found by adding or subtracting four 
seconds for every minute of longitude the place lies east or west of 172° 30’.

The time could, as at piii bé "üteiizona at Wellington by the 
 meridian transit, as it will be most convenient that the time-balls at the 
different ced should be dropped at 1 p.m. of the adopted statute time, 
. which for Wellington would be at 1h. 9 m. 11:5 sec. mean time of place.
