THE YOUNG NATURALIST. 



men of H. abmptaria taken at Hornsey Kise. Mr. W. G. Pearce contri- 

 buted specimens - of A. alni, four A. strigosa, and One 5. idvcz, while very 

 dark forms of D. capsophila were exhibited by Mr. Adkin, and fine rows of 

 'N. rubi, X. scolopacina and X. rurea, all shewing much variation, were 

 shown by Mr. Southey. Mr. C. H. Williams had several very pretty forms 

 of the common 0. dilutata, and also a most peculiar melanic form of P. 

 syringaria ; while a book containing a large number of most excellent 

 photographs of objects under the microscope, most kindly sent up by Mr. Gills, 

 of Bath, added materially to the interest of the proceedings. Mr. Rolfe also 

 exhibited some specimens, which however, I must decline to notice. 



An expedition also took place on Nov. 16th to Eppiug Forest, when most 

 of the usual species were observed, though hardly so numerous as they are 

 generally ; it was also noted that the size both of H. aurantiaria and H. 

 defoliaria seemed considerably below what it should be.

OUR LONDON LETTER. 



There is little to record at the present time. 0. dilutata has been very 

 abundant, and H. aurantiaria, H. defoliaria, and H. pennaria are all to be 

 takeu now in the various woods round London. The specimens, however, do 

 not appear to be up to the averaage size, some of the aurantiaria more par- 

 ticularly being exceptionally small. The Haggerston Society have just had 

 their annual exhibition, and the South London hold theirs on December 3rd, 

 and by all accounts it promises to be fully up to the average. A fungus 

 foray was made over Epping Forest a few days since by members of the 

 Hackney Microscopical Society, with very great success, the recent wet 

 weather having been highly favourable to those who pursue this branch of 

 Natural History. Unless anything of interest happens I shall now take leave 

 of the readers of the Y.N. until the return of spring once more gives me 

 something to chronicle.
