Cally Loch, which was looking very beautiful. In the loch itself 
were great masses of the white flowers of the curious Aponogeton 
distacliyum , a South African plant, which seems to be perfectly hardy 
here. Other plants observed were Castalia speciosa f. minor , Pilu- 
laria globulifera , and Scirpus fiuitans. Near Hatton we were struck 
by the luxuriance and great size of the wild juniper bushes. Passing 
Dowally Loch and St. Colme Loch, neither of which proved to be 
very productive, we descended upon Dowally Church, where the 
“jougs”were tried upon one of the party. Near Guay Agrimonia 
odorata was observed in the same station where it was found a few 
years ago. Here we turned southwards and went down the River 
Tay to an island below Dalguise Bridge. On the shingles here the 
great abundance of Silene maritima was remarked, and on the island 
the luxuriance of Thalictrum minus. Returning to the mainland, 
where we saw Verbascum Thapsus , we arrived at another island, 
where a large bed of Calamogrostis Epigeios was found. In passing 
through Dunkeld Grounds Equisetum pratense was noticed, and on 
the top of the Cathedral a number of plants of the Common Broom 
—a curious place for such a plant. 
The morning of 4th July found us at Dalguise Station, where 
Anthemis arvensis is abundant on the railway line, and is increasing. 
Passing Dalguise House, we examined the ravine of Kincraigie 
Burn, near Stewartfield, and then ascended the hill to Loch Skiach. 
This loch, which is about 1300 feet above sea level, seems to be 
admirably adapted for supplying Perth with water by gravitation. 
In it we noticed Potamogeton prodongus and Isoetes lacustris , and on 
its shores Tofieldici palestris. Passing over the watershed into the 
Breadalbane district, we descended by Balnamuir Burn, finding 
Sedum villosum , Hippuris vulgaris , Utricularia intermedia , and U 
minor , Ca?'ex pauciflora , &c. Near Logierait Salix ambigua was 
noticed. 
On 7th July we set off to explore a glen which I had often 
thought ought to be examined. This was Glen Garr, a narrow valley 
to the west of Bankfoot. Starting from that village we went up the 
Garry Burn till we reached the glen. Here we did not find very 
much to reward our exertions. In an old slate quarry Allosorus 
crispus and Grimmia Doniana were found. Although not confined 
to slate, these plants are very often—in Perthshire—associated with 
it. As we passed over the watershed to the glen which descends to 
Birnam the various shades of colour assumed by Erica cinerea were 
noticeable. In addition to plants of the ordinary hue (which were, 
of course, the most abundant), some with very bright pink and others 
with white flowers were observed. These rosy pink forms of this 
heath seem often associated with the slate rocks. 
On 14th July we went to Dollar and up Dollar Glen, following 
for part of the way a different route from the one which we pursued 
in our excursion there last year. In Dollar Glen fine plants of Scolo- 
pendrium vulgare were noticed. As these are, fortunately, inacces¬ 
sible, they are likely to escape the ravages of the ffern-collector, 
though, for that matter, the ferns of the glen are to a certain degree 
protected. Passing Castle Campbell, we went up the Burn of
