Magnetic Observations. 



2b7 



The new data, being the observations at Albany of the magnetic 

 declination between the years 1874 and 1892, are my own observations 

 and are now for the first time made public. 



My station of observation has been in the grounds of my residence 

 on Western avenue in this city, and is marked by monuments and ref- 

 erence points which may hereafter be found and identified by means 

 of the accompanying diagram. The magnetic station is marked by a 

 brown-stone monument having a copper-plug, with cross, set as centre.
