MARINE BIOLOGICAL STATION AT PORT ERIN. 37 



the living animals will settle this. Speaking of P. pellucidus, 

 Bell says — ' Tables generally distributed in the body- wall, but 

 not numerous.' The truth is that they are closely packed, 

 apparently in every part of the body- wall. I doubt whether 

 the distinction he draws between the ' tables ' of P. pellucidus 

 and those of P. drummondi is valid." 



Miss Tozer reports her research as an attempt to investigate 

 the sensory nerve endings in the eye muscles of the fish, 

 Gadus virens, by means of the methylene blue method. This 

 attempt yielded no very definite results as the method was only 

 partially successful. It only revealed a few very fine myel- 

 inated nerve fibres and non-myelinated endings near the 

 tendon muscle junction, and gave no indication of the total 

 supply. 



Miss A. Porter, D.Sc, spent some time in the late autumn 

 at Port Erin working at parasitology. She examined such 

 fish, molluscs and other invertebrates as were available at that 

 time, and found various interesting parasites at which she hopes 

 to do further work at Port Erin in the future. 



Mr. W. Bygrave, B.A., formerly of Cambridge and the 

 Marine Biological Laboratory at Plymouth and now Science 

 Master at King William's College, Castletown, is from time to 

 time pursuing research work at the Port Erin Laboratory. 

 The investigation on which he has started consists in comparing 

 the stomach contents of samples of herring, obtained in the 

 commercial fisheries round the Island, with the plankton 

 occurring at the same time at the same locality. We have 

 made arrangements with the skipper of a fishing boat to pre- 

 serve for us the necessary herring samples, and at the same time 

 to take hauls of the plankton net with which we have supplied 

 him. These samples and gatherings are sent to the Port Erin 

 Laboratory to await the detailed comparison which Mr. Bygrave 

 will make, both as regards their bulk and their microscopic
