place. There are three species I more particularly allude to — 

 the Blue-bottle (Centaurea ajanus), found in cornfields ; the 

 small Stinging Nettle (Urtica urens), in other districts to be seen 

 on almost every dunghill; and the Wall-Barley (Hordcum 

 murinum), so abundant elsewhere under walls and by waysides. 

 All these plants are mentioned in the " Flora Bathoniensis " 

 either as "frequent," or "common," or "not uncommon," 

 though I never myself succeeded in finding any of them. 

 Neither has Mr. Broome, who has botanized over this district so 

 much longer than myself, found two out of the three, nor the 

 third except in a very few instances. With respect to the 

 Hordeum murinum, Professor Babington seems to have discovered 

 his mistake afterwards, as in the supplement to his book he has 

 mentioned it as "rare," giving but one locality for it, "the 

 river-side at Twerton Bridge." I find, however, in Mr. Sole's 

 " Illustrations of British Grasses," to which I have already dra\vn 

 your attention, some notes relating to this species, which, as his 

 book was never published, it is desirable to put on record, and 

 which tend to shew that even in the above locality this grass may 

 T)ossibly not be indigenous. Mr. Sole, under the head of Holcus 

 mollis, another rare grass in this neighbourhood, observes — " We 

 are lucky in having neither Darnell, Wall Barley, nor this species 

 of couch about Bath." Underneath, hoAvever, he adds — " I am 

 sorry to find, since Avriting the above, that Wall Barley has 

 found its way hither, and established itself in Brett's timber-yard, 

 Bath ; it is to be feared it will flourish too well in the vicinity." 

 Again, under the head of the Hordeum murbmm itself, he says, 

 " this grass though common in most places is not so about Bath," 

 underwriting as before, " N.B. But is since arrived here." 



These remarks by Mr. Sole were 'made sixty-seven years ago. 

 I have not been able to ascertain whereabout in Bath Brett's 

 timber-yard was, as' there is none, I believe, of that name now. 

 But it is clear, by our not finding this grass in the neighbourhood 

 at the present day, that though introduced, probably by accident,
