quiring more porseverancc and punctuality tlian most persons are willing 

 to bestow, we have a very large number of applications ol'tliis kind whicli

This list is increasirig partly by voluntary offers and partly from a re- 

 quest made to the observers in tlie ^iouthern and Western States to enlist 

 others in the Avork, in their respective districts. The number is not per- 

 mitteil to diminish, if it can be avoich'd, by the discojitinuance of an ob- 

 server. When such is reported to us as probable, the retiring observer is 

 iniifoi'mly requested to place the register in the hands of a suitable succes- 

 sor, and kec]) the chain oi observations unbroken. The increase has been 

 marked within a few months past, and it is satisfactory to note that the 

 greater number come trom the Southerii and Western States, in which our 

 obsei'vers have hereiolore iieen but eoniparafiveiy few. Fi-om the occa- 

 sional discontinuance of sonu', and the hetpuiit additions uf others, our 

 list is constantly fluctuating in effective sti'engfh ; the numerical force can 

 be known, hou-evei', at any time. 



It is proper to state that for extra liniitai stations we lia\f an observer 

 each in Nova Scotia, Camida West, 'New (xrenada and Bermuda, from all 

 ofwhich manuscri{)t registeis are received, except frouj the last. His ex- 

 cellency Charles Elliot, governor of Bermuila, has ordered that the Royal 

 Gazette, containing a weekly register of llie wealhei in Herniuda, be regu- 

 larly sent to this Institution. 



Observations have been received at tlie Smithsonian IriStitution, duiing 

 the year 18-31, from the following persons:
