1835.] Observers in India and Africa. 359 



The days they have been induced to fix on and recommend for these observations 

 are, the 21st of March, the 21st June, the 21st September, and the 21st December, 

 being those of or immediately adjoining to those of the equinoxes and solstices, 

 in which the solar influence is either stationary or in a state of most rapid 

 variation. But should any one of those 2\st days fall on Sunday, then it will be 

 understood, that the observations are to be deferred till the next day, the 22nd. 

 The observation at each station should commence at 6 o'clock a. m. of the 

 appointed days, and terminate at 6 o'clock p. m. of the days following, according 

 to the usual reckoning of time at the place. During this interval, the Baro- 

 meter and Thermometer should be read off and registered hourly, or at all 

 events, at intervals not more than two hours asunder ; and the precise hour and 

 minute of each reading should be especially noted. 



For obvious reasons, however, the commencement of every hour should, if 

 practicable, be chosen ; and every such series of observations should be accompa- 

 nied by a notice of the means used to obtain the time, and when practicable, by 

 some observation of an astronomical nature, by which the time can be indepen- 

 dently ascertained within a minute or two*. As there is scarcely any class of 

 observations by which meteorology can be more extensively and essentially 

 promoted, it is hoped that not only at every station of importance in this colony, 

 but over the whole world, and on board ships in every part of the ocean, 

 individuals will be found to co-operate in this inquiry. Every communication 

 of such observations, addressed by channels as secure and as little expensive as 

 possible to the Secretary of this Institution, will be considered as highly 

 valuable." 



3. — Statistics and Geology of Kemaon. 



We perceive by our advertisement page, that Dr. J. McClelland is about to 

 publish, by subscription, his Observations on the Statistics of Kemaon ; embracing 

 an account of the Rocks, Minerals, and Mines, Organic Fossils, Waters, Population, 

 Wild Animals, Birds, and Insects of the province. Together with Observations on 

 the Goitre, on Earthquakes, and Climatology. The whole including a Geologi- 

 cal Map and Section of the district, with various other drawings, coloured. 



Mr. McClelland is appointed to join Dr. Wallich in his approaching trip to 

 explore the Tea Districts eastward of Assam. The expedition has also the advan- 

 tage of an able second Botanist in Dr. Griffiths, Mad. Med. Est., and as it 

 will meet Captain Jenkins in the valley, its geological strength will have nothing 

 to desire. But we confess we think an Astronomer, or at least a Surveyor ac- 

 quainted with Astronomy should be added, to make the scientific corps perfect — ■ 

 to note the position of the new points they will visit, and to sketch some of its 

 glorious features. When the British Government sends a party to set up Steam 

 Boats on the Euphrates, every adjunct of science, language, and art is superadded : 

 why should the Government of British India be less efficient in their preparations 

 for so interesting and profitable a voyage of discovery ? 



* For example, the first appearances and last disappearances of the sun's upper 

 and lower border, above and below the sea horizon, if at sea or on the coast,— of, 

 on land, the exact length of the shadow of a vertical object of determinate length 

 on an horizontal level, at a precise moment of time (not too near noon), &c.
