positions of the various instruments. It may be well to explain that in 
December, 1867, Mr. Symons transferred to Mr. Griffith a series of fourteen 
gauges which had been constructed with a view to testing several questions 
as to the best material for the funnels of rain-gauges, the loss from evapo- 
ration under various conditions, the influence of the angle of the rim of the 
gauge, and some other points. On notice of Colonel Ward’s intended re- 
moval being received, the extent to which the objects originally contemplated 
had been attained was considered. It was thought that the four years’ ob- 
servations at Calne, corroborated as they were by two years at Castleton 
Moor, and current observations at Rotherham had sufficiently indicated the 
law of decrease of rain, out of the influence of buildings; it was therefore 
resolved that three only of the elevation gauges should be remounted in 
their old form, and that the rest of them should be placed on the roof of the 
Rectory and outbuildings, in such positions as to give some indication of the 
influence of, and amount of error due to, various positions of roof gauges. 
Professor Phillips, F.R.S., and Mr. Symons have both, independently, been 
investigating the relation between height above sea-level and amount of rain- 
fall as indicated by both new and old stations in the Cumberland district.
