 on all the hills about Llanberis, and on other hills in WaleSj which 

 is indeed nothing but the common one. 



" I am sure we were at the right place, for we found there 

 Lycopodium Joliis juniperiJ' In the lake at Cown we found the 

 common Subularia folio rigido^ mentioned to grow only in Phynon 

 Vreech, and the Junci^olia cochlearice capsulis,* pretty plentifully, 

 which relieved me very much of our disappointment of not seeing

 where you observed the Subularia fragilis, folio longiore, ei tenuiore^ 

 cast out of the lake, we found it growing there in great plenty. 

 During our stay at Llanberis, we had very hard and uncomfortable 

 lodging at the inn, and with difficulty got a young man to be our 

 interpreter and guide/' 



After this excursion Mr. Brewer remained the winter and the 

 greater part of the next year at Bangor, making it his residence, 

 and taking his excursions to Snowdon and elsewhere, often accom- 

 panied by the Rev. Mr. Green, and Mr. William Jones. While in 

 Wales it it was intended that he should have gone over to Ireland 

 to make a botanical tour through that kingdom but that expedition

 known to him before, and sent them to Dillenius to determine the 

 species and fix the names. A catalogue has been seen of more than 

 two hundred mosses, many of which were ill-ascertained before, aU
