108 Notes on the Excursions of 1900. [Sess 
purpose of observing the aquatic plants which grow here. 
Through the courtesy of Mr Affleck, the overseer on the estate, 
the party also visited the Prestonfield grounds, and returned 
by Newington. 
On 18th July we again visited the loch. Our best find 
was the Butomus umbellatus, or flowering rush, in full bloom. 
This plant appears to have been overlooked for some years, 
and was latterly considered to be extinct here. 
VII—MILLPORT. 
Saturday, June 2, was devoted to visiting the Marine 
Biological Station near Keppel Pier. The day was as fine 
as could be desired, and those botanically inclined had plenty 
of opportunity to indulge themselves on the way out to the 
station. The principal attraction was a dredging excursion, 
but this proved a failure. Owing toa strong current running 
contrary to the direction of a light wind, the dredge could not 
take the bottom sufficiently for a good haul, and only two 
sea-urchins were brought up. The rest of the time was spent 
in inspecting the museum and laboratories, which latter are 
being much improved by the addition of concrete sea-water 
tanks, so that it will now be possible to keep material for any 
length of time. A steamer is to be added to the equipment 
of the station, and with these increased facilities some good 
work will no doubt be done. 
VIIL—HOWIETOUN FISH-HATCHERY. 
A joint excursion was fixed with the Natural History Society 
of Glasgow to visit the Howietoun Fish-Hatchery on Saturday, 
June 9. Owing to the interest attaching to the place, it was 
expected that there would be a good attendance of members, 
but the inclemency of the weather prevented this. Several 
members proceeded by the morning train to Stirling, with the 
intention of visiting Bannockburn and the other historical 
places in the neighbourhood, under the guidance of Dr 
Watson. On arriving at Stirling it was found useless to
