door of the mansion-house by the proprietor, the late Sir George 
H. Leith-Buchanan, who acted as conductor over the remainder 
of the estate. A number of fine trees were noted, and. measure- 
ments taken. A record of these measurements appears in the 
Transactions of the Natural History Society of Glasgow, vol. 
VI., page 164. The party returned to Balloch wa Mount 
Misery, from which a charming view of Loch Lomond was 
obtained. 
The second excursion in this district, which had for its objective 
point Caldarvon Loch, took place on 14th June, 1902. The loch 
is on the estate of Caldarvon, about three miles from Balloch 
station. Through the kindness of the proprietor, ). S. Mackenzie, 
Esq., a couple of boats were placed at the disposal of the party, 
who were thus enabled to visit the islands, on one of which two 
nests of the tufted duck, one containing six, and the other eight 
eggs, were seen. On the southern shore of the loch a coot’s nest 
with six eggs was observed, and another with two young birds 
also attracted attention. Amongst the more noticeable plants 
found growing on the margin of the loch, the tufted loosestrife 
(Lysimachia thyrsifiora, Ait) and the bogbean (dlenyanthes 
trifoliata, Z.) are worthy of special mention. A species of 
bladderwort ( Utricularia) was also found in the loch near its 
western extremity, while specimens of (Vitella flexilis, Ag., were 
obtained in the deeper water. The white and yellow waterlilies 
(Nymphea alba, L. and Nuphar luteum, Sm.) grow in great 
abundance in the loch, and a large part of the surface is covered 
by their floating leaves. Along the roadsides in the vicinity of 
Caldarvon a number of interesting plants occur, such as the 
twayblade (Zzstera ovata, Br.), the butterfly orchis (Habenaria 
chlorantha, Bab.), and the lesser wintergreen (Pyrola minor, L.).

An excursion, starting from Dumbarton (where a visit was paid 
to the Rock) and proceeding. up the right bank of the Clyde to

Dalmuir, took place on 8th August, 1891. The records are 
entirely confined to the botany of the district, which is of special 
interest. The following is a list of the more interesting plants 
observed on this occasion :—
