LICHENS (Licbenes] 



Few English counties can boast of so rich a lichen flora as Corn- 

 wall, and few have been worked by so many good lichenologists. Half 

 a century ago the Rev. T. Salwey and the Rev. F. Pentreath published a 

 list of Cornish lichens in the second volume of the 'Transactions of the 

 Penzance Natural History and Antiquarian Society. The celebrated botanist 

 Mr. W. Borrer frequently joined Dr. Ralfs and the Rev. T. Salwey in 

 rambles after rare species. In 1880 a more complete list of the lichens
