direct reference was made by me to the Doctor or any speci- 
men of his Psilophyton , none of which resemble the fossil 
plant described by me, I think he has no right to compel 
me to read over all his learned and voluminous works how- 
ever much he might think that I should be benefited by so 
doing. 
As to the Doctor’s opinion that my Manx plant resembles 
the Buthotrephis Harknessii of Nicholson, all I can say is 
that I have carefully compared the two figures of the speci- 
mens — Dr. Nicholson having kindly sent me a copy of his 
paper published in the Geological Magazine for November, 
18G9 — and I see no reason to change my views. My Manx 
plant is without question the most like Professor Lesquer- 
eux’s figured specimen of Psilophytum cornutam, whatever 
that plant may prove to be, of all the fossil plants that have 
ever come under my notice. Any one may judge for him- 
self by comparing the published figures of the specimens.
