I have the satisfaction to acquaint my readers, that the 

 Meteorological Tables and Remarks, which will hereafter 

 appear in this Journal, will be extracted (as the present has 

 been,) from the journals of Mr. Luke Howard, whose Trea- 

 tise on Clouds, inserted in the present number, and long 

 known and valued by the public, will make it unnecessary 

 for me to exprej»s, in any direct termis, that sentiment of 

 obligation, which myself, and the other cultivators of sci- 

 ence, must entertain for his researches. W, N,
