tions cut by the streams, beds of micaceous and hornblende slate interstra- 
tified with crystalline limestone, but the upper part, forming the great 
bulk of the hill, consists of granular quartz, compact and homogeneous, 
and capable only of supporting a meagre vegetation. The summit, which 
terminates in a narrow plain about a mile in length, is covered almost 
exclusively with lichens and a few mosses. To the botanist it affords 
probably as few attractions as any mountain in Scotland. The plants 
gathered on the flanks and lower slopes were the following, viz. —Thalic- 
trum alpinum, Genista anglica, Rubus Chamemorus, Hippuris vulgaris, 
Saxifraga -aizoides, 8. hypnoides, var., S. stellaris, Cornus suwecica, 
Vaccinium Myrtillus, Pyrola secunda, Hmpetrum nigrum, Salix arbu- 
tifolia, Listera cordata, Tofieldia palustris, Carex rigida, Festuca 
ovina, var. viripara, and Lycopodium Selago. Aspecimen of Polystichum 
Lonchitis was gathered, having 130 fronds. At the summit, the rocks 
were crusted over with Lecidea geographica, and amongst other lichens; 
Cetraria Islandica, Scyphophorus bellidiflorus, and Cladonia rangi- 
ferina were not unfrequent. Among the mosses—Pogonatum alpinum, 
Dicranum fuscescens, Andreea rupestris, Hypnum denticulatum, Tri- 
chostomum lanuginosum, and Fissidens osmundordes, | 
The remainder of the paper was occupied with an account of a visit to 
the Tummel, Killicrankie, Fortingal, Glen Lyon, and the Falls of Moness.

3. On the Homologies of the Floral Organs of the Phanerogamous and. 
higher Cryptogamous Plants. By Joun Lowe, M.D., Lynn. 
In this paper the author attempts to explain homologies which exist 
between the Phanerogams and Phylloid Cryptogams. He says—‘‘ My 
view is briefly this: that the spores of ferns should be regarded strictly 
as flower-buds, containing in embryo the reproductive organs, which be-. 
have just as we might imagine a phanerogamous floral bud to do if de- 
tached from the parent tree, and made to complete its development after- 
wards. The prothallus I regard as the calyx or phylloid expansion, pro- 
tecting the male and female organs; the rootlets of it as the nutrient 
vessels of the buds, true roots not being produced until the development. 
of the embryonic cell. That this view is a correct one I am strongly led 
to believe, from having observed since I wrote out the above idea a sin-. 
gular monstrosity in the spores of Adiantum teneruwm. These I have 
found developed as terminal buds from the extremities of the veins of the 
pinnules. The buds, which are covered by and produced from the under 
surface of the spore case, which is distinctly shown to be a folding of the, 
margin of the leaf, are now developed into living plants instead of spores, 
and were in the initial state surrounded by paraphyses,
