2. — Climate of Vera Cruz. 

 Allusion was made in our last, to a meteorological register kept by Fray Juan, 

 at Vera Cruz ; as the tables whence the notice was derived are in manuscript, we 

 think it will be interesting to publish the following abstract of them, drawn up for 

 the purpose of elucidating the subject of the barometric tide.

3. — Range of the Barometer at Berhamptir. 

 We also alluded to the barometric observations made by the late Dr. Alexander 

 Russell, at Berhampur, in 1820 — 21 : of these too, we take this opportunity of 

 putting on record an useful summary made out by a friend, and reduced to the 

 temperature of 32°, by applying the correction calculated from the thermometric 

 register kept in Culcutta, for want of the local observations : the differences cannot 

 be very great.
