both peculiar to large Beech woods. The pond-hunters were busy with 

 rod and bottle fishing up examples of aquatic life from pools and 

 streams. We have no reports of the catches in some cases, but Dr. 

 Cooke has furnished us with the following list of species he met with 

 during the afternoon : — 



ALG^. DESMIDS. 



Zygnema cruciatum (Ag.) Hyalotheca dissiliens 



Zygnema stagnalis Closterium Dianaj 



Spirogyra tenuissima (not Closterium Leibleinii 



common) Closterium rostratum 



Spirog>Ta turpis Closterium gracile (rare) 



Cladophora fracta Spirotasnia condensata 



DIATOMS. Cosmarium cucumis 



Cocconema lanceolatum Cosmarium botrytis 



Epithemia turgida Staurastrum muricatum 

 Pinnularia viridis 



He states, however, that he found very little animal life in the col- 

 lection, except ; — 



PROTOZOA. ROTIFERS. 



Amffiba guttula Rotifer vulgaris 



Actinophrys sol Metopidia acuminata 



(Dr. Cooke adds, " There may be one or two additions to this list, 

 as there are a few specimens which I have not had time to examine 

 sufficiently to fix the names with any certainty.") 



About five o'clock the whistle was sounded, and the members found 

 their way in groups to the Wake Arms, where a well-served and sub- 

 stantial tea awaited them. Then, making for the train, the forest road 

 towards Theydon was taken, a halt being made in the woods to listen 

 to the genial conductor, Dr. Cooke, as he discoursed on the wonders 

 of the water, the curious Algse, Diatoms, Desmids, Rotifers, &c., which 

 a little searching would reveal in the ditches, pools, and swamps of 

 Epping Forest. The rain came down during the Doctor's address, 

 and he made some humorous allusions to the vanity of human wishes 

 as exemplified by the afternoon's proceedings. But he said he had 

 very great faith in Epping Forest as being perhaps the best spot for 

 the naturalist within forty miles of London. As an instance, he men- 

 tioned that, on the previous Saturday afternoon, he had found at 

 Snaresbrook three species of Algse hitherto unknown in Britain — 



namely, 



Hydrianum heteromorphum (Reinsch) 



Sphterozosma secedens (De Bary) 



Closterium linea (Perty). 

 This result showed that the persevering hunter might still find worlds 

 to conquer in our own districts. ,
