THE MAGNETIC SURVEY OF NEW ZEALAND. EFL 
which the secular change over the time during which the 
obsservations are in progress can be deduced, (3) to obtain 
the present conformation of the iso-magnetic lnes. The 
purposes of (1) and (2) are for the present identical, and 
groups of stations have accordingly been established at 
Invercargill, Dunedin, and Christchurch. It is proposed 
to extend these to other towns, and especially to those 
on or near the sea coast, while for (3) the stations have been 
spaced at intervals of, roughly, 20 miles from Stewart Island 
and Orepuki, in the south and south-west of New Zealand, along 
south-east, east, and north coast of the South Island ; the number 
of stations at which observations have so far been made is sixty- 
nine. 
Your committee learn with pleasure that it is the intention 
of Professor M‘Aulay and Mr. E.G. Hogg to carry out a survey 
of Tasmania, and they anticipate that his work in conjunction 
with that in progress in New Zealand will lead to a valuable 
increase in our knowledge of the magnetic distribution of this 
part of the Southern Hemisphere, and they would express the 
hope that the interest which your resolution has undoubtedly 
aroused in these colonies may induce others in the part of Aus- 
tralasia as yet untouched to take up this work. The early years 
of the new century would in that case see the removal of the re- 
proach under which we at present exist—that we are standing 
in the way of progress in magnetic knowledge.
