182 Meteorological Results made at Penzance, in Comwall,for 2 1 Years. 



The thermometers I use are two double registers, — one made 

 by Newman, and the other by Cary, — which are placed in a 

 north-eastern aspect, in such a manner as not to be acted 

 upon by reflected heat. 



My rain-gauge is placed in my garden at the level of the 

 ground, entirely free from the influence of buildings or trees. 

 The gauge is exactly six inches diameter at the edge of the 

 brass rim at the top. The basin is made of pewter c 2\ inches 

 deep. The tube attached to the basin is three inches long, 

 tapered to about £th of an inch at the point. The measure is a 

 glass cylinder graduated to a quarter of an inch of water, or 

 1 784 T «o grains, nearly 1 784*796 grains.

 slightest shower.
