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 ap- 

 pointed days, and terminate at 6 o'clock P. M. of the days fol- 

 lowing, according to the usual reckoning of time at the place. 

 During this interval, the barometer 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 eve- 

 ry hour should, if practicable, be chosen, and every such se- 

 ries of observations should be accompanied 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 independently ascertained withm a minute or two. As 

 there is scarcely any class of observations by which meteorolo- 

 gy can be more extensively and essentially promoted, it is 

 hoped that not only at every section of importance in this colo- 

 ny, 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." 



This recommendation was followed by Mr. Roberton, of 

 the Royal Society of London, whose observations for the 22d 

 of June, and 21st of September and December, 1835, are re- 

 corded in the first three tables. They are copied from the 

 London Atheneum. A committee of the Institute commenced 

 similar observations in December, and tables 4 and 5 contain 

 the record of the 21st and 22d of December and March. For 

 the purpose of making this design generally known, these ta- 

 bles were pubhshed in the Albany Daily Advertiser, and also 

 on a separate sheet, and sent to every person whom the com- 

 mittee knew to be engaged in meteorological observations. 

 At the same time, John S. McCord, Esquire, Vice-President 

 of the Natural History Society of Montreal, and a correspond- 

 ing member of the Institute, at the request of an officer of the 

 Hydrographical Corps, commenced similar observations in that 

 city, the results of which, for December and March, are given
