it would be obviously premature to speak of numerical 
values, by which the magnetic forces at one part of the 
globe may be compared with those of another, or with forces 
of other descriptions ; and for the same reason it is desirable 
to abstain for the present from notices of the geographical 
positions which particular lines, or as some may deem them 
critical points, in the magnetic resultants may occupy on the 
earth's surface at the present epoch. Such notices could 
only be as yet provisional, and liable to the amendments 
which more exact and extended calculation must be expected 
to produce. We are just beginning to profit by the col- 
location and study of the great body of facts which has been 
collected.” * 
The third volume of the Hobart Town Observations will 
discuss the peculiarities of the climate of Hobart Town, as 
exhibited in the extensive series of Meteorological Obser- 
vations which haye been made.
