JJ84 A LIST OF EPirnVTFS. 



in the mud of which the shore at this part is composed; it is cast up by 

 the sea, and found in small pieces, the largest not larger than a finger, 

 and of a longi-spherical form, and much of it is attached to, and deposited 

 on, other substances; I myself picked up some pretty specimens. The 

 stones and piles of the pier are covered with Barnacles and Mussels, and 

 there is scarcely a piece of weed without them; but of other shells I have 

 seen few or none. 



This is the wrong season for Marine Ornithology, and accordingly, I 

 have only seen the usual kinds of Gulls and Tringoe; but had I the 

 opportunity, I think I might make an extensive collection of Algae; this, 

 however requires to be ^'taken at the flood," for sunshine and exposure soon 

 render the more valuable and delicate worthless, and you must give yourself 

 up to the pursuit, which I am not able to do. But I have already 

 exceeded my limits, so for the present I shall conclude.

A LIST OF EPIPHYTES GROWING ON THE WILLOWS 

 IN THE HOLMES, THIRSK. 



BY MR. THOMAS FOGGITT. 



I HAVE of late been much interested in observing the way in which 

 plants migrate from one place to another, and the manner in which they 

 instal themselves in situations where they would be least expected to appear. 

 There are many plants which not unfrequently establish themselves upon 

 the trees. When growing in such situations they may be Parasites, or 

 Epiphytes — terms which are sometimes confounded, but which are, in 

 reality, considerably difierent; Epiphytes merely appearing casually, but 

 Parasites springing from the interior of the tree, and deriving their vital 

 principle and nourishment therefrom. 



The annexed list will probably serve to illustrate to what extent 

 Epiphytes may be found: — * 



Sycamore, (Acer pseudo-platanus.) — Growing on three trees. 



Raspberry, (Rubus idacus.) — On one. 



Brambles, (Rubus corylifolius and csesius.) — On many, their drooping 

 branches pendent over the waters, or reaching unto the ground. 



Dog Rose, (Rosa canina.) — Forming a large bush on one tree, and 

 sparingly on several others. 



Haidhorn, (Crataegus oxycantha.) — On five trees, six or seven feet high. 



* When preparing this paper, a friend placed in my hands "Lees' Pictures of Nature," 

 and directed my attention to a list of Epiphytes growing on the Willows on the banks of 

 the Teme, in Worcestershire, the plan of which list I immediately adopted for the construction 

 of the present one.
