rived at by Ivory, (a circumstance to wliicli Dr. Apjohn 

 has alluded in his first paper on the Dew-point, without, 

 however, having been at the time aware that Ivory's result and 

 his own were perfectly identical,) and the same is probably 

 true of Dr. August of Berlin, as may be collected from the 

 following passage of Dr. Suerman's Thesis, p. 69 : — 



" Formulam psychrometricam ex theoria mixtionum aeris

 there is a likelihood of these interesting representations be-
