348 REPORT— 1897. 



ruy, associated, as at Kirk Michael, with Salix herbaceci, will afford an 

 opportunity for a closer study of the conditions under which it occurs. 

 As Mr. Reid points out, it is especially desirable to investigate the 

 relations of this Arctic fauna to the beds containing the elk remains. 

 The following is Mr. Clement Reid's report : — 



" The following species of plants and animals were obtained on wash- 

 ing samples of the deposits. Beds C, D, and F are all worthy of closer 

 examination ; for it is important to ascertain whether there is any 

 evidence in the Isle of Man of a mild period after the melting of the ice, 

 and before the deposition of the bed with Arctic willows. If the shell- 

 marl (F) containing the Megaceros remains was formed during a mild 

 interval, the complete disappearance of the Irish elk, so difficult to under- 

 stand, may be due to cold or to scarcity of food during a less genial 

 period. This point has never been cleared up in Ireland, notwithstanding 

 the numerous remains of the Irish elk that have there been obtained. 



Bed A. 



Ranunculus flammula, L. I Hydrocotyle vulgaris, L. 



Potentilia tormentilla, L. \ Potamogeton, i^p. 



" Also caddis cases and eggs of insects. 



" The plants are all common Isle of Man species. 



Bed C. 



Poterium officinale. I Moss. 



Salix herbacea, L. I Lepidurus (Apus) glacialis. 



Carex, sj). I Daphne (winter eggs).

" Numerous leaves of the dwarf Arctic willow Salix herbacea and frag- 

 ments of the Arctic crustacean Apus glacialis, neither of them now 

 living in the Isle of Man, point to climatic conditions considerably more 

 severe than those now holding in the district.

Bed D. 



Ranunculus aquatilis, L. 



„ flammula, L.

Littorella lacustris, L. 



Potamogeton crispus, L. 



Carex.

Beetle (elytron). 



" The plants are widely distributed species still living in the Isle of 

 Man. Littorella is usually northern. 



BedF.

 Insect remains. 



" This marl thus far has yielded nothing to indicate the climatic con- 

 ditions."
