ters ; and the two sub-species were accordingly named by their pro- 

 posers E. macrocarpum [Stephens) and E. brachycarpum [Leighton). 

 The former is the common wild form, the latter being the common 

 garden form in Britain. On the specimens of Mr. Thwaites the fruit 

 is generally under an inch in length ; but a few of the pods on many 

 of the specimens range from an inch and a half to even two inches 

 in length. 



Potentilla rupestris (Linn.). — A specimen communicated by Miss 

 Harvey, with a label to indicate that it was collected on Ben Lawers, 

 by Dr. Greville. It required the authority of a trustworthy botanist, 

 like Dr. Greville, and the exhibition of an actual specimen of the 

 species, to make the locality credible ; and even now it is difficult to 

 conceive how so conspicuous a plant could have been overlooked on 

 a hill very frequently visited by the best practical botanists of Britain. 



Saxifraga umhrosa (Linn.). — Specimens from " Craig y bairns " 

 and the "Woods near Dunkeld," communicated by Miss Harvey. 

 The leaves of these examples correspond with those of the Yorkshire 

 specimens from Mr. Tatham, in being crenate, and rather obtusely 

 so. Thus, both the Scottish and the English apparently wild plants 

 correspond with the examples usually sent from the Pyrenees, and 

 not with the serrated or dentated forms which prevail in Ireland ; but 

 it has already been abundantly established that neither form is pecu- 

 liar to the Pyrenees or to Ireland. 



(Enanfhe pimpinelloides (Linn.) and CE. Lachenalii (Gmel.). — 

 Additional examples from Dr. Bromfield and Mr. Fitt, in illustration 

 of the various stages of growth in these two species. 



Mr. Munroe communicated a paper " On the Potato Disease."

Living Heath and Fossil Tree. By Joseph Sidebotham, Esq. 



I SEND you the following statement of facts, and leave your readers 

 to draw their own conclusions; for I must confess I never could ar- 

 rive at any to my own satisfaction. 



Six or seven years ago I was told that there was a curious fossil 

 tree to be seen in a stone-quarry, at a place called Tintwistle, about 

 fifteen miles from this town, and that there was a living branch grow- 

 ing from it. Being rather curious to see this wonder, I took the first 

 opportunity of visiting the place, having the same friend for my guide. 

 Tintwistle is a small village situated in a wild, romantic valley.
