their old poems : but all are of use to any that would compose a dictionary of 

 their language ; which was anciently, considering the narrowness of their 

 knowledge as to arts and sciences, doubtless very copious. 



I saw no coins found there, besides the Roman gold coin of Valentinian, jun. 

 formerly mentioned ; several of our old English since the conquest ; and one 

 cast brass piece, inscribed with Runic letters, which I take to have been a 

 Danish amulet. Several of our old British monuments, called Kaer, Karn, 

 Cromlech, &c. we met with ; and find that they distinguish them by the same 

 names. What were peculiar to themselves, were their high round towers for 

 belfrys; their round entrenchments, commonly called danes rathes; and the 

 elf-arrow heads of flint. 



About Sligo and Bali Shany we had good success as to figured stones; where 

 we met with variety of astropodia and astrorrhizae, or modioli, not yet figured 

 or described, with other curiosities of that kind. In the same neighbourhood, 

 on the mountains of Ben Bulben and Ben Buishgen, we met with a number of 

 the rare mountain plants of England and Wales, and three or four not yet dis- 

 covered in Britain, Mr. Heaton's chamaedrys alpina is a common plant on those 

 hills, as also on divers other mountains and heathy grounds in Connaught and 

 Munster. 



In the isle of Aran (near Galloway) we found plenty of the adianthum verum, 

 and a sort of matted campion with a white flower. In most of the mountains 

 of Galloway and Mayo grows an elegant sort of heath, bearing large thyme- 

 leaves, a spike of fair purple flowers like some campanulas,* and viscous stalks. 

 I know not whether it be any thing related to the cisti ladaniferae. In the same 

 places pinguicula flore carneo minore is a common plant, and a sort of ros solis, 

 which I take to be undescribed. 



Sedum serratum foliis pediculis oblongis insidentibus is exceedingly common 

 on all the mountainous tracts of Mayo, Galloway, and Keri. On the moun= 

 tains of Keri, sanicula guttata grows in abundance ; together with some other 

 rare plants,- as the arbutus, cotyledon hirsuta, cirsium humile montanum cy- 

 noglossi folio polyanthemum R. Syn. Alchemilla alpina pentaphyllos ; sanicula 

 aizoides inter guttatam et sedum serratum ambigens ; veronica procumbens 

 maxima, an N. D ? &c. 



Pentaphylloides fruticosa-j^ we found plentifully among lime-stone rocks, on 

 the banks of Loch Crib, in the county of Galloway ; and Dr. Merret's vaccinia 

 rubra foliis myrtinis crispis, a very beautiful plant, we found to be no rarity in 

 this kingdom.
