Later Mr. Jamieson announced as a newly discovered fact 
that the styles of grasses are not essential parts of the pistil. 
This statement any tyro can readily show to be incorrect, 
and one has only to look at the figures published with 
Mr. Jamieson’s paper on this subject to see how inadequately 
he has understood the matter with which he is dealing. 
Both of these so-called discoveries are quoted as leading 
results of the work of the Agricultural Research Association, 
of which Mr. Jamieson is director, and I mention them now 
as indications of the difficulty there is about attaching 
importance to the discoveries which Mr. Jamieson 
announces. 
W. Epaar Evans, B.Sc., exhibited a series of casuals 
found in the Edinburgh district, chietly Ranunculacee and 
Crucifere. 
Mr. F. C. CrawrorpD showed Pyrethrum einerariefolium 
—a composite grown in the south of Europe and used when 
crushed as an insect powder; also three interesting Carices, 
Carex helvola, Blytt., C. trinervis, Degland., and C. involuta, 
Bab. 
Mr. J. RutHErrorD Hitt also showed some preparations 
of the above Pyrethrum. 
Mr. G. West exhibited some forms of the Scottish Limnetic 
Phytoplankton, illustrated by slides and specimens. 
Mr. R. L. Harrow exhibited a series of plants in flower 
from the Royal Botanic Garden. 
On behalf of Dr. A. W. Bortuwick, a series of lantern 
slides was shown illustrating the transport of forest produce, 
chiefly in America and on the Continent. 
JAMES WATERSTON, B.D., gave some interesting notes on 
the Flora of St Kilda, with lantern illustrations.
