oak woods there was an abundant and varied g-round carpet. 

 The coast was visited from Runswick to Saltburn. After two 

 months of severe drought, the vegetation was not at its best. 

 One feature is the marked distinction between the Boulder Clay 

 slopes at Runswick, Port Mulgrave, and Hummersea, and the 

 adjoining dry slopes of Oolitic and Liassic weathered rocks. 

 The Boulder Clay is grassy and supports a large variety of 

 species of other plants. The dry, sandy, and shaly slopes are 

 covered with Bracken, Purple Bell Heath, Heather, and other 

 plants of poor soil liable to drought. The abandoned alum 

 works at Boulby showed the development of a plant-covering 

 on bare soil ; at present the grass, Atra flexiiosa, forms an open 

 -association of isolated tufts on the older banks, the Bird's Foot 

 Trefoil also forms large, yellow, conspicuous patches, while the 

 Ling and Purple Bell Heath are well-established in moist 

 hollows.

MITES, 



Lincolnshire Water-mites. — At the meeting of the Lincoln- 

 shire Naturalists' Union, held at Stamford, on 29th June, a 

 sample of water from an old pond on the disused brick hills 

 was taken. The contained water-mites have been referred to 

 Dr. George and are as follows : — Arrhemiriis globator, both 

 sexes, and some small green Arrhenurus not easily determin- 

 able ; Ciirvipes = Fiona (of Piersig.), Limnes.ia hisirionica, L. 

 koenikii (?), Hydrochorentes. The largest male was accident- 

 -ally lost before the examination was concluded. It had 

 a curious deformed palpus on one side, the like of which the 

 •examiner had not seen before. Dr. George is preserving the 

 specimens, about 66 in all, for further examination. — Arthur 

 Smith, Grimsby.
