236 Anniversary Address. 



This is a topic I shall not at present occupy you with. I 

 may, however, observe that an Urn and a drinking vessel 

 have very recently been found on the farm of North Dodd- 

 ington, a lithograph of which may some time find a place in 

 the Club's Proceedings. 



The approaching issue of the Northumberland and Rox- 

 burgh Ordnance Maps will facilitate the study of Geology 

 in the field of this Club's work. In future the facts there 

 stated may be relied upon, and fresh observations should be 

 attempted. 



It may be considered by the Club whether a Committee 

 should be formed to make Meteorological experiments and 

 observations and to send in a report. 



Apart from Geology, Mineralogy has been little cultivated 

 by members of our Club, and as a matter of commercial im- 

 portance the propriety of so doing might be thought of by a 

 section of our members. 



A list of Mineral Wells should be registered ; also any in- 

 dications of mineral veins. 



I am also reminded by our Secretary that the lists of 

 Coleoptera and Lepidoptera which have appeared in the 

 Club's Proceedings, should be systematized. 



Hemiptera have been partially catalogued ; Hymenoptera 

 have been merely touched upon ; Diptera have been scarcely 

 studied at all ; in a few orders scarcely a species has been 

 registered. 



To give an idea of the rapid march of scientific discovery 

 Dr Giinther estimates the number of species described up to 

 1831 at 70,000, at the present day at near 350,000. It is 

 estimated by Mr Waterhouse that 12,000 species of insects 

 are contained in our museums which have received no de- 

 scription, and that probably less than one half of existing 

 insects have been collected. 



It has been with reason thought, that little or no dredging 

 having been done in the neighbourhood of Holy Island and 

 the estuary of the Tweed, and with the great improvements 

 that have latterly occurred in dredging, that the lists of 

 Mollusca, Crustacea, Annelides, and Zoophytes generally
