= | ae From each of these stations, returns have been regularly 
received since their respective dates of completion. Previous to 
_, . this, there had been received returns of seven months of obser- 
__ ‘vations in a temporary observatory at Toronto, and of six at St. 
: es Helena. All the observations, as soon as received, have been 
° regularly transmitted to Prof. Lloyd, and after examination by 
him, handed over to Col. Sabine, under whose superintendence, 
assisted by Lieut. Riddell,—(the state of whose health, has un- 
fortunately compelled his return from Toronto,) they will be 
published, Government having, on the application of the Royal 
Society, taken upon themselves this additional expense.- In con- 
sequence of this arrangement, the reduction and printing of the 
observations are now in progress. he portable observatories of 
the Hrebus and Terror were put up at Kerguelen’s Land, and 
also at Van Diemen’s Land. At the former station, the May and 
June terms were observed,—at the latter, those of August and 
September, 1840. During the stay of the expedition at these 
stations, the magnetometers were observed hourly ; and the reg- 
ular work of the observatory at the latter station under the diree- 
tion of Lieut. Kay has been begun, and will be continued on 
this doubly laborious plan of hourly intervals for the ordinary ob- 
servations, while on the term-days, all the three magnetometers 
will be observed at the same instants of time, but at intervals of 
two and a half minutes,—the means of confronting this vast in- 
crease of labor being supplied by the colonial government, as 
administered by that ever active and zealous friend of science, 
Sir J. Franklin. In addition to this, and for the sake of mul- 
--oecasions for observing the correspondence of magnetic 
perturbations with auroral discharges, one hour out of every 
twenty four, (viz. from-Ih. 50m. P. M. to 2h. 50m, P. M. Got- 
tingen mean time, commencing from Jan. 1, 1841,) will be oc- 
cupied with observations of the magnetometers, at intervals of 
two and a half minutes, in this order, viz. Bifilar, declination ; 
Vertical force, declination B,D; V, D, &c. It is to be hoped 
‘that some of the European ehocubilatiie will, at least occasionally, 
furnish observations i in correspondence with these.»
