ON MAGNETICAL AND METEOROLOGICAL OBSERVATIONS. Jl] 
Ac. Term observations.—Should they be discarded (as seems the general 
impression) or increased in number and made weekly, as Dr. Lloyd 
recommends? Should Gottingen time be used in them? Should a 
term be broken off if no disturbance be apparent at the usual time 
of greatest disturbance ? 4 
A d. Disturbances.—Should the inquiry into disturbances rely on term- 
observations only, or should extra observations be made whenever 
they are supposed to be in progress? Should a few continuous ob- 
servations be made.at the usual hours of maximum disturbance, to 
detect them? Ought the readings of the instruments during them 
to be registered at definite instants of Gottingen mean time, or at 
the instants of great jumps or turning points? Ought any special 
provision to be made for their observation during Sir John Frank- 
lin’s stay near the pole ? 
A e. Instruments.—Ought the present instruments to continue in use, or 
any, and what changed? Ought magnets to be interchanged? 
Should self-registering magnetic apparatus to register disturbances 
attaining a certain magnitude? New instruments—induction mag- 
netometer—theodolite ditto—M. Lamont’s new inventions ? 
A f. Additional observations—Should any, and what, be in future made? 
Ba. Daily Meteorological Observations.—Should any immediate change be 
made in the hours? in the instruments? Should night observations 
be discontinued ? 
Bb. Meteorological Terms.—Should these be discontinued? Should they 
be modified as to the extent of the observations ? 
Be. Meteorological Instruments——Should self-registering instruments be 
used? and what? Should encouragements be held out for their 
improval ? and of what sort? who to be the judges, and what the 
conditions of their introduction into use? At what times and on 
what understandings are new instruments generally to be intro- 
duced? Should a system of itinerant instruments of comparison be 
adopted? at what intervals ? and in what order? 
Bd. Additional Observations.—Of thermometers, wet and dry, at several 
elevations in the air? Of temperatures of soil at several depths ? 
Of atmospheric electricity ? with what instrument? Peltier’s? 
Gourjon’s? Mr. Wheatstone’s new principle and apparatus? of 
barometer continuously during storms? Should the wind be regis- 
tered at each observation? Should any other class of phenomena 
be observed ? 
Ca,cb. Of the Ordnance and Admiralty Stations.—Should all be con- 
tinued in activity or not, and which? If the same number be re- 
tained, is it desirable to continue or change the stations? Should 
any endeavour be made to procure additional colonial stations ? 
Ce. The Hast India Observatories—Should any and which of them be 
continued? The expense of Simla being particularly heavy, is it 
desirable to recommend zés continuance ? 
Cd. Permanence or Temporary continuance.—For how long a period would 
it be desirable to continue each station seriatim? Should any one 
or more be permanent ? 
Ce. Observers and Assistants.—Should the force of each observatory serta- 
tim be diminished or increased ? 
Da. Survey and Auxiliary Stations —Should any and what local surveys 
be recommended? Should the observatories be given up, would any 
local surveys deserve recommendation? Should the observations
