II.—Contributions to the Study of the Old Red Sandstone Flora of Scotland. I. On Plant-Remains from the Fish-Beds of Cromarty. II. On a Sporangium-bearing Branch-System from the Stromness Beds

It was the intention of Dr Kidston and myself to deal with the main plant-remains of the Old Red Sandstone of this country in preparation for a systematic account of the flora. I cannot continue the work alone without expressing in affection and gratitude how much I owe to my association with him in it. The loss of Dr Kidston's experience, insight, and judgment in dealing with the obscure and peculiar plants of this early period can hardly be estimated. No further results of our joint work had been prepared for publication; but, since we had for some years made common stock of our observations and notes on the subject, Dr Kidston's views on many points are known to me and will be utilised wherever they apply.

page 262 note ¶ It is desirable to state explicitly that there is, at present, no specimen establishing the occurrence of Psilophyton princeps in the Middle Old Red Sandstone of Scotland. This well-characterised species is so far only known from the Strathmore Beds in the Lower Old Red Sandstone of Scotland. From its occurrence in Middle Devonian rocks in Germany and Canada there is, of course, no improbability in its being discovered in the Middle Old Red Sandstone. But no specimen, so far as I know, establishes a clear record of it, although the name has frequently been loosely applied to the remains under consideration here.
