mot. 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. 

 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. The portable observatories of 

 the Erehus and Terror were put up at Kerguelen's Land, and 

 also at Yan 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 direc- 

 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. FrankUn. In addition to this, and for the sake of mul- 

 tiplying occasions 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, decHnation ; B, D ; V, D, &c. It is to be hoped 

 -that some of the European observatories will, at least occasionally, 

 furnish observations in correspondence with these. 



The first report of Lieut. Ludlow, the director of the Madras 

 Observatory, and the first month's observations, have been receiv- 

 ed. It commenced regular observations on the 1st of January, 

 1841.
