376 TRANSACTIONS AND PROCEEDINGS OF THE [Sess. lix. 



As we were leaving the rocks the mist became very 

 dense, but we all got down safely. We found the Lochy 

 in flood, and had to wade a deep water before we could 

 reach our carriage. We were all drenched, but got back to 

 the hotel in good time for dinner, and none of the party 

 suffered afterwards from the drenching. 



Thursday, 9th August. — The morning was fine, and we 

 resolved to visit Loch Lomond and Ben Voirlich. Accord- 

 ingly we left Tyndrum about 8 a.m., per West Highland 

 Eailway, for Ardlui, at the head of Loch Lomond, which 

 was reached in forty-one minutes. Here the party divided. 

 One party botanised on the sides of Loch Lomond, and 

 amongst other plants collected may be mentioned Drosera 

 anglica. Huds. ; Circcai cdpina, L. ; Carum verticillatum, 

 Koch.; Scutdlaria galcriculata, L. ; Hymenophylluin tun- 

 Iridgcnse, Sm. ; H. unilatercde, Willd.; and the moss Diphy- 

 sciu7n foliosum. The other party ascended Ben Voirlich, 

 a mountain 3092 feet high, being exactly 100 feet lower 

 than Ben Lomond. The day was very hot, and consequently 

 mountaineering was somewhat arduous. We reached the 

 top about 1.30 P.M., and had a fine view from the summit. 

 We saw most of the alpine plants which are known to grow 

 on this mountain, a record of which is found in A^ol. XL of 

 the Society's Transactions, at page 70, by the late Professor 

 Balfour. We met with no plants not mentioned in that 

 list, but we found a large quantity of Ptcris aquilina, L., 

 with the fronds all crested. There would be at least an 

 acre of the hillside covered with this fern, and nearly every 

 plant was abnormal. It is somewhat remarkable that this 

 variety had not been recorded previously from Ben Voirlich 

 when we consider its abundance, and the fact that the hill 

 has been so frequently visited by botanists. Several plants 

 were dug up, and it is hoped that some of them will grow. 

 This variety is not unknown to cultivators of ferns, but, so 

 far as I am aware, is not common in a wild state. 



Friday, 10th August. — The morning was again fine, and 

 after an early breakfast we started for Beiun Laoigh and 

 Ben Oss. The whole party travelled together as far as the 

 farm of Cuninish, when we separated into two parties, one 

 going towards Beinn Laoigh, with the view of examining the 

 rocks to . the smdh of the great corrie, a portion of the
