6 Address of the President. 



lohiwm augustifolium, probably introduced. But the plant 

 of special interest was the little yellow water lily, Nuphar 

 kahniana, a plant very local in Scotland, Watson giving only 

 the counties Lanark, Argyle, Elgin, Inverness, and we may 

 now add Dumfries. This plant is considered identical with 

 that of the North American species, which had been named 

 after Kalm ; minima and pumila are synonyms, the latter 

 most generally adopted. The day was dry with a strong gale 

 of wind, and the bottom of the loch on the top of the mud 

 appeared as spread over with a pale covering. This was 

 blanched plants of Hypnwm fluitans, which sunk to the 

 bottom when the water was withdrawn. Extremely little 

 moluscous life appeared. 



Towards evening the party divided, — the one to inspect 

 some graves near a reputed old battlefield, but which time 

 did not allow them to examine thoroughly : the other sought 

 the Crawick Water to see the junction of the old rocks with 

 the carboniferous series, which is well seen close to the old 

 mill, and also the stratification of the latter, of which several 

 good and interesting sections are presented, very fossiliferous, 

 but here specimens are very difficult to procure entire. The 

 members again met together at the ruins of Sanquhar Castle, 

 which they examined under the guidance of Dr. Simpson, 

 and I cannot do better than refer our members to the excel- 

 lent little work of the Rev. Doctor, "History of Sanquhar." 



Several ladies, both members and visitors, attended, and 

 took great interest in the exploration of the Black Loch 

 crannog ; and when the members separated there, they made 

 an excursion (on their own account) up the Euchan (ythan) 

 Water, and brought in specimens of (jampanula latifolia, 

 which grew plentifully in several hollows of the glen, and 

 also Vicia orobus in seed, abundant here, but by no means 

 a common plant in the county. This glen alone would well 

 repay an examination, and there is a full day's work in it, 

 zoological, botanical, geological, and antiquarian. The mem- 

 bers, having left the castle and inspected and measured the 

 Black Loch canoe, dined a large party at the Queensberry
