2 ASTRONOMICAL OBSERVATIONS MADE AT PANAMA. 



" The observations for longitude were made by myself and Lieutenant A. W. Whip- 

 ple, and those for magnetic dip, declination, and intensity, by Lieutenant A. W. Whip- 

 ple and myself, but chiefly by the former. 



" The results are as follows : — 



Latitude, 8° 57' 12 ".15 north. 

 Longitude, 5' 17" 57" .63 west of Greenwich. 

 Magnetic declination, 6° 54' 37 ' east, 

 dip, 32° 00' 00". 



" intensity,* 0.87507 (uncorrected for diflerence of temperature). 



" The place of observation was the northwest bastion of the fortification surround- 

 ing the city of Panama, and is north of the Cathedral 2". 15, and west of it 6".85 (in arc). 



" The results for latitude and longitude above given agree closely with those given 

 by Bauza. His place of observation was the Cathedral. 



" The results obtained by Espinar differ widely in longitude. The precise place where 

 he observed cannot be ascertained. 



" I have not been able to obtain the determination of latitude and longitude made by 

 Sir Edward Belcher, nor have I ascertained the spot where his observations were made. 



" I send you also my determination of the longitude of Chagres, as obtained by the 

 transportation of chronometers from New York. The time at Chagres was determined 

 by observations on east and west stars with a Gambey sextant."
