and plaice not less than 9 inches long, from the same 

 catch, should be sent every fortnight either to Piel or 

 Liverpool as is most convenient. Uncommon Inverte- 

 brates should be preserved and sent to the Liverpool 

 Laboratory for identification. 

 " 3. — E xamination of Shellfish Beds. 



"The Morecambe mussel beds and the cockle beds near 

 the Kibble Estuary should be examined at intervals. 

 Other shellfish beds should be treated in a similar manner 

 as time permits. The transplantation experiments should 

 be continued, and samples of the transplanted shellfish 

 should be sent to Liverpool as often as they are taken. 



" The usual bacteriological examinations will be made 

 from time to time as the Committee requires the informa- 

 tion. But if desirable any one bed can be systematically 

 examined and reported upon. Several inspections have 

 been made during the present year of the Morecambe 

 mussel beds, and a bacteriological examination has 

 already been made of the mussels at Llanfairfechan. 

 " 4. — F ish-marking Experiments. 



" Nearly 1,000 fish will have been marked and 

 liberated before the end of the present year. A con- 

 siderable number have been returned — varying from 

 5 per cent, to 50 per cent, of those liberated according to 

 the " Station." Tables and charts are being prepared 

 shewing the results, and the whole matter will be 

 discussed in Professor Herdman's forthcoming report. 

 Mr. Johnstone proposes to give a preliminary accounl of 

 the results of these experiments at tin" next meeting of 

 the Scientific Sub-Committee. II is proposed, if the 

 Committee agree, to carry on these experiments during 

 the next year, with whatever modification the result- of 

 the past experiments may suggest. It is proposed to 

 mark flounders as well as plaice.
