will be little or no effect produced from this cause (as proved 

 by the observations of Mr Walker), because there is a supply 

 of waters from the eastward. It would therefore appear that, 

 around the shores of the district under consideration, when the 

 winds which traverse it have considerable force, the levels which 

 would obtain in calms are considerably disturbed, and conse- 

 quently minor effects of the same kind are caused by less 

 powerful winds, according to their velocity. To obtain, 

 therefore, true heights in this district above the sea, which 

 should correspond above a level in both channels, supposing 

 such level to exist, calm weather is essential for accuracy. —

 ovate, blunt, spreading ; nectariferous (/lands, 5 at the base of the tube. 

 Stame/ts 5, as long as tlie corolla, inserted into it, and adliering as
