Meteorological Observations, Napa-Keang, (Loo-Choo]) 1848-49. Mult by Dr. Bettelheim 



Read Jan. 16th. 1852. 



Philadelphia, February 1 (>///, 18f>2. 

 Dear Sir : 



The meteorological observations taken at the Loo-Choo Islands are the result of the 

 industry of Rev. Dr. Bettelheim, M. D., a missionary at Napa-Keang, Grand Loo-Choo 

 Island. fV.'ing but a limited supply of paper, he was obliged to crowd his notes; and 

 as I ha^' but a few hours in which to copy them, it was impossible to arrange them in a 

 different form. He had a very fine marine barometer, and a thermometer of Fahrenheit. 



The force of winds, &C., were placed according to usual nautical parlance. 



His residence was upon the Capstan Rock, Lat. 26° 13', N.; Long. 127° 51', E. 



I hope that, from the fact that no observations of any length of time having been pre- 

 viously made in that portion of the ocean, these may be of some interest. 



Very truly.
