The quantity of rain measured near his house and also at Alverton, 

 a quarter of a mile to the N.E. of the Museum, at an altitude of 

 40 feet, have been ])ublished in. groups of years with our own ; 

 and test observations have been constantly noted in my garden, 

 at Strangways Terrace, 90 feet above the sea, where a float gauge, 

 and more recently a Stevenson's stand, have been added to the 

 older arrangements. 



The establishment of one of the Government Observatories at 

 Falmouth, furnished with self-recording instruments, has provided a 

 valuable standard for comparison between the neighbouring coast 

 and Truro, together with more largely based averages ; and the re- 

 sults of the comparison of different stations liave been very ably 

 given in the Re[)orts of the Royal Cornwall Polytechnic Society. 

 The inquiries systematically carried out in the harbour on the tem- 

 perature of the sea, serve to supplement Mr. Whitley's previous 

 researches over a wider area, and are of the highest interest and 

 value. 



At various stations in Cornwall, observations have been care- 

 fully made and recorded during the whole of the above period, 

 and through a great part of it in others. Among the former may be 

 classed Bodmin, Falmouth, and Helston, and in the latter division 

 Plymouth, — which in relation to meteorology may be included in 

 this county, — Liskeard, Altarnun, Penzance, and Scilly. These 

 records will not be given at all at length, but they will be used 

 for a comparative estimate of the influence of the position of the 

 several localities on their climate. A condensed statement wdl 

 also be given of the contents of a series of like records of obser- 

 vations of earlier date, commencing with those of Dr. Huxham of 

 Plymouth, in his work " De Aere et Morbis epidemicis," and 

 extending from 1728 to 1752. The next in succession is Ihe 

 MS. of the famous Dr Borlase, noted at Ludgvan, near Penzance 

 beginning in 1754 and ending with August, 1772, for the loan of 

 which I am indebted to his descendant, Mr. \V. Copeland Borlase 

 M.P. It is marked by scrupulous regularity in its entries. 



This record is followed by a third, in the form of diagram, 

 exhibiting the daily results noted, a fjw miles east of Truro, 

 for each month separately, from 1765 to 1782. The two 

 volumes containing this beautiful example of depiction 

 of natural phenomena were kindly given to me by the late
