PIONEERS IN LOCAL BIOLOGY. 27 



our local species. Dr. Baker Edwards was a very energetic 

 and successful worker in aquaria, thus becoming a pioneer 

 in an advanced department of our local Biology. 



The Liverpool Naturalists' Field Club, since its estab- 

 lishment in 1860, has held many expeditions for dredging, 

 and excursions to various parts of the coast. At the close 

 of each year, prizes in the form of books on Natural Science 

 are given to the most successful collectors. Two prizes have 

 been gained in Algae, two in marine shells, and two in 

 Hydrozoa and Polyzoa. In the latter classes, the collection 

 made by Mr. and Mrs. Howard Chapman, wholly from 

 specimens found on the shore, was remarkably good, and 

 contained many rare forms. 



The Chester Society of Natural Science has published its 

 Proceedings in three parts, well worthy of the scientific 

 work they represent, which does honour to the distinguished 

 founder of the Society, Charles Kingsley, Canon of West- 

 minster. 



Dr. Henry Stolterfoth, M.A., in Proc. C.S.N.S., Part 2, 

 1874, gives a List of Diatomaceae found in Chester and the 

 district, and Cwm Bychan, N.W. Very many of the species 

 were collected in the estuary of the Dee. The list is copious, 

 and occupies twelve pages. Fifty -eight genera are included, 

 of which Navicula alone is represented by eighty species. 

 The same author contributes to Part 3, a paper on " Surface 

 dredging on the Dee." The paper describes many special 

 forms, of microscopic life found on the surface of the estuary 

 of the Dee, with the author's method of collecting them. 



Mr. J. D. Siddall has contributed to Part 2 an excellent 

 paper on the Foraminifera of the River Dee. About 134 

 species are recorded, and Mr. Siddall makes some valuable 

 observations upon the living Foraminifera.*

 District," p. 44.— Ed.
