ON THE KEW OBSERVATORY. 131 



date the pressure is set down at the hours of 9 and 15. [The frequent re- 

 eurreuce of the proves the great insensibility of the Lind anemometer.] 



In column Y the forces of wind acting upon the balance-anemometer are in 

 grain weights. 



In column Z the changes of the moon are placed opposite to the nearest 

 hours (which had been previously written for other purposes) to those at 

 which they occurred. 



Under the title " General Remarks and Occasional Observations," Mr. 

 Galloway's nomenclature of atmospheric appearances is pretty closely adhered 

 to. It will not always be found strictly logical and consistent, but I could 

 not improve it without risk of damaging the general sense. When we came 

 to the 7th of Nov. 1843, it seemed better to copy his notes from the book, 

 in which they were originally set down, than to take his general accounts 

 compiled from that book and from memory the next morning. 



A few words should be here devoted to the observer, &c. 



The observations of all kinds were made almost exclusively by Mr. Gallo- 

 waj', whose notes were first written, some on papers prepared for the pur- 

 pose, and kept in the quadrant-room below ; others in the above-mentioned 

 book, kept in the electrical observatory, and more frequently inspected. 



I am quite satisfied that he has executed his task better than could have 

 been expected ; but must add emphatically, that had our habits and qualifi- 

 cations been always adequate to the attainment of extreme accuracy, our in- 

 struments and other means would have been far from being so. 



In short, although the electrical part of the journal (even under these cir- 

 cumstances) is more complete and accurate than any such hitherto recorded, 

 yet this year's work {i.e. from the 1st of August 1843 to the 31st of July 

 1844) must, in spite of all our efforts, be considered upon the whole, and 

 principally, as educational and experimental. 



The form of the Journal is copied as closely as circumstances of space, &c. 

 would permit, from the Astronomer Royal's admirable Tables of " Ordinary/ 

 Meteorological Observations" at the Greenwich Royal Observatory.
