Mrs. Gregor, of Trewarthenick, where the observations were 

 chiefly made by a member of that family. 



The next notes in our possession were made by Mr. Jamos, 

 at Redruth, from iTSy to 1806 ; and the registers kept at 

 Penzance by Mr. E. C. Giddy, from 1807 to 1827, are closely 

 followed by Mr. Moyle's, at Helston, continuous subsequently 

 with our own. The rainfall has been noticed at many other 

 places. 



The observations of earlier date are of course defective in 

 various ways, which will be pointed out ; but their value is still 

 considerable, and they help to make up a nearly continuous 

 secular record of unusual length of the climate of one district, 

 and that marked by distinct characters. It may further be re- 

 marked that each set of observations, noted as they are with 

 scrupulous attention to the method adopted, is complete within 

 itself, so that it presents a correct view of the monthly and yearly 

 averages and variations within its own cycle. Taking all these 

 materials into consideration, an approximate estimate may be 

 obtained of the climate of Cornwall during the last century and 

 half.
