236 Yorkshire Naturalists at Harewood Park. 
var. reticulata, almost exclusive ; Avion circumscriptus, A. sub- 
fuscus var. aurantiaca (Loc), Zonites nitidus 2? Anodonta cygnea, 
and Unio pictorum occurred in the large lake. 
Sponcia.—Mr. A. R. Sanderson noted the fresh-water 
sponge, Spongilla fluviatilis in profusion. 
Botany.—Mr. C. A. Cheetham writes :—A fairer sight 
would be hard to find than that provided by the Marsh Marigold 
and sedges in the swamps, and the Blue Bells and Anemones 
with the modest Woodsorrel and Yellow Weaselsnout in the 
woods. Some very deeply coloured masses of Anemones and 
Woodsorrel offered subjects for discussion. 
Around the shore of the lake the naturalized plants pro- 
vided an added interest ; Solomon’s Seal growing in the turf, 
the mighty inflorescence of Gunnera on the shore edge, and the 
long semi-floating rhizomes of the Sweet Flag in the lake all 
looking quite happy in their new home. 
To a ‘ splitter’ delighting in varieties and forms the Marsh 
Marigold held out open arms, some clumps had the sepals 
all imbricate, others had them widely separate, and again in 
others the sepals were nipped up at the top, giving them a very 
narrow appearance. 
Amongst the few species of sedges noted, one singled out 
the great masses of C. paniculata so well known in the neigh- 
bouring valley at Adel. Growing in the moist spaces midst these 
sedge clumps, the little waterblinks were bravely flowering. 
The mosses were of a similar nature, nothing startling but 
quietly interesting; some parts of the turf being carpeted 
with Mnium affine and in others Climacium dendroides in place 
of the usual Mnium horneum, and on the partly submerged 
tree trunks or more especially the dead ones around the lake, 
Aulacomnium androgynum held up its little stalks with knobs 
of gemmae at the apex, whilst on similar trees in the woods 
was Tetraphis pellucida, with its nest of gemmae filling this 
place. 
With the waterblinks the pear-shaped capsules of Phys- 
comitrium pyriforme were to be seen in quantity. A list of 
some forty species of mosses was handed to the Leeds Natural- 
ists’ Society for inclusion in their records of this district. 
Mr. A. R. Sanderson writes that he gathered two specimens 
of Mycetozoa, viz., Trichia varia and Reticularia lycoperdon, 
and the polypore P. sqguamosus. . 
GEOLOGY.—Mr. S. Margerison reports that he and Mr. 
Gaunt saw a large gritstone glacial boulder, which is known 
as the ‘Greystone’, in the south-east portion of the Park. 
He did not measure it, but it would be at least ro ft. by 6 ft. 
by 6 ft., z.e., well over 20 tons in weight.
