from this more general work some experiments were made 

 with a view to collecting data for an enquiry into the causes 

 underlying certain marked features of algal distribution. 



Miss L. Baker and Miss E. M. Blackwell spent some time 

 investigating the lichens of the littoral and other regions, and 

 produced a preliminary list. The mosses and liverworts of 

 the district were collected and classified by Professor J. B. 

 Farmer, F.R.S., and Mr. R. J. Tabor, of London. 



It is hoped that several papers at present in course of 

 preparation will be published as an outcome of the work done 

 by the Botanical School at Port Erin during the Easter vacation, 

 1914. 



Bio-Chemical Researches. 



The researches carried out on the Bio-Chemical side 

 during the year 1914 have been concerned with two main 

 problems. In the first place the nutrition and metabolism 

 of marine animals have been studied over prolonged intervals 

 by means of the respiratory exchanges ; and secondly the 

 variations in alkalinity of sea-water at various periods in the 

 year have been investigated. The second problem is related 

 to the first, because the variations are mainly produced by 

 changes in the balance between photo-synthetic activity of 

 plants, and the metabolic oxidising activities of animals. 



The results of the metabolic experiments have been 

 published in two papers which appeared in the Transactions 

 of the Liverpool Biological Society, Vol. XXVIIL, 1914, 

 viz. : — 



1. The nutrition and metabolism of marine animals : The 

 Tate of oxidation and output of carbon-dioxide in marine 

 animals in relation to the available supply of food in sea- water, 

 by Professor B. Moore, Edward S. Edie and Edward Whitley. 



2. The nutrition and metabolism of marine animals : The
