1770 PHILOSOPHICAL TRANSACTIONS OF THE RoyaL SOCIETY OF 
Lonpon: The early numbers of this valuable series, at 
least from 1664, were consulted at the Library of the 
American Philésophical Society. They are especially 
valuable for early records of observation for the construc- 
tion of instruments and for philosophical discussions. I 
quote at p. 18 of ‘‘ Climatology ’’ the experiments of Dr. 
Beal and Dr. Wallis, 1664-1675, on the construction of 
the barometer and its adaptation to climatological pur- 
poses. Robert Boyle is accredited with this ‘‘ most ex- 
traordinary invention of the world.’’ Dr. Halley, Mr. 
Townley, Dr. Plot, of Oxford, and Dr. Lister engaged in 
these experiments, kept the record, and began predicting 
the weather. In 1723 a form for daily observations is 
given and reference is made to registers kept by Dr. Lin- 
ing and Isaac Greenwood in the United States.
