This boreal moss^ discovered inTeesdaleDurham in 1901 by 

 Messrs. Horrell and Jones, was iound by Mr. D. A. Haggart in

Whilst, owing to the drought, the Pentiand reservoirs and their 

 feeding streams were at a very low level^ five species of Riccia were 

 found growing in abundance on the exposed and drying mud, R. soro- 

 carpa, R. glauca, R. crystallina (first record for S c o 1 1 a n d), R. glau- 

 cescens or Lescuriana, R. fluitans. The latter species associated with 

 Fossombronia cristata occurred along the bank of a stream.

During a flying visit of three hours to the Island in the early 

 Summer of 1904 three scarce species of aquatic mosses: Fontinalis anti- 

 pyretica, Racomitrium aciculare and Grimmia apocarpa, were obtained 

 and examined. Seventeen zoological organisms were found upon them, 

 also two Desmids (Penium sp. and Closterium sp.) and Peridinium tabu- 

 latum. A. and E. S. Gepp.

The author mentions 49 species of Ferns with remarks on their 

 distribution under each species. He states a new species, Trichomanes 

 formosanum, with a short remark as follows: „Closely allied to Tri. vi-

 frond." B. Hayata.

A critical review of J. E. Clements „Research Methods in Eco- 

 logy". The authors welcome the book as ^the most ambitious and most 

 important work on Ecology that has been published during the last 

 seven years". The critici'sm is directed chiefly to some of Clements' 

 conceptions as regards physiology. The opinion that the work of the 

 plant physiologist is too much confined to his laboratory is met by the 

 reply: „Till we have a rational physiology . . . . we can scarcely expect 

 to gain a great deal by the extension of the arena of the physiologist 

 to ecological problems. Grude concepts carried into a wider field cannot 

 give anything but unsatisfactory and inconclusive results^, and the place
