October 5th. — The Rev. H. H. Higgins mentioned that last Monday was the 

 first time the Free Museum, William Brown Street, was reopened to the 

 public in the evenings, and that it would continue to be open every Monday 

 evening. 



Mr. I. C. Thompson exhibited under the microscope, and made some 

 remarks upon, some remarkable and little-known Cladocera, a branch of the 

 Crustacea, which he had recently found at various depths in the Cumberland 

 and Westmoreland lakes. One of these — the Lcptodora hyalina — is an ex- 

 quisitely transparent creature about a quarter to half an inch in length, and 

 has the appearance when alive of a minute fragile glass canoe rapidly beating 

 its way through the water. He had found it in Grasmere, Easedale, and 

 Thirlmere lakes, its presence in the latter possibly jjossessing some interest 

 in the near future to Manchester water-drinkers. The other forms 

 Mr. Thompson exhibited were Bythostreiihcs ccderstroinii, Bosmina longi- 

 rostris, an animal not uncommon in London drinking water, and 

 Hyalodaphnia hahlhergensis, a most eccentric-looking microscopic crustacean, 

 with an immense eye surmounted by a long-pointed head, comically re- 

 sembling a dunce's cap. Mr. Thompson strongly recommended to the 

 members the study of the minute animal life of our lakes and ponds as 

 affording a rich field for research, and one in which a large amount of 

 original work is yet to be done. 



An interesting discussion followed, in which the President, the Rev. 

 H. H. Higgins, Dr. Carter, and others took part. 



The President made some remarks on " Microscopy as a special branch 

 of scientific study," in the course of which he said that Microscopy was 

 now more especially employed either for amusement, recreative study, or as
