COUNCIL — SEPT. 1912 -APPENDIX D —82 — 



meeting. The distribution and respective numerical frequency of the sexes and the 

 rate of growth in the various districts should especially be studied. 



Prof. Ehrenbaum supported these proposals ; the investigations with regard to 

 the Eel and the results hitherto obtained which had met with the greatest atten- 

 tion from all sides, had greatly increased the reputation of the hiternational 

 Cooperation for the Study of the Sea, and it must therefore be considered a point 

 of honour to retain upon the programme the continuation and furtherance of these 

 investigations even at the risk of occasionally encroaching upon the field of fresh 

 water fishery. 



Prof. Henking recalled the fact that the inclusion of the Eel in the programme 

 of investigations had already been discussed on the occasion of the meeting in 

 Stralsund in 1903. The "Deutscher Seefischerei-Verein" had thereafter undertaken 

 observations as to the ascension of the Eel fry on the German coasts. He had 

 himself given information as to the results of these observations at the meeting 

 of the Central Council in 1909 (Proc. Verb, des Réunions, p. 61) and a MS. dealiug 

 with these observations was now ready to be printed. As to whether the proposed 

 observations should cease at the boundary of fresh water, and in what manner, 

 was, he thought, a question for the Council to decide. For the rest, he supported 

 the proposals. 



Dr. Trybom briefly called attention to the fact that the "Proposals" sub- 

 mitted by Dr. Schmidt and himself with regard to future investigations did not in 

 any way consider or differentiate upon the question of work being carried out in 

 salt or fresh water. 



Dr. Sandman stated that the investigation would also be of great interest to 

 Finland. He produced an eel measuring 27 cm which had been taken in Finnish 

 inland waters and must originate from imported English Eel fry which had been 

 laid down three years ago. Eels of less than 31 cm in length had never previously 

 been observed in Finnish waters. 



Prof. D'Argy Thompson supported the proposal and expressed his satis- 

 faction at the support which it had received. He considered it most practical to 

 discuss the three points of the proposal separately (see Appendix K). 



Point I was agreed to without further discussion. 



Prof. D'Argy Thompson asked whether the proposers desired to make a 

 more comprehensive statement of Point II in their proposal. 



Dr. Trybom did not consider this necessary, as the printed Proposal dealt 

 fully enough with the subject. The proposers had not therein given any definite 

 scheme of investigations, being of opinion that the task would present points of 

 variation in the various countries. Attention should, however, in all cases first
