soft and tho lab(4 was tor* thin. Xone of tlicsc liad 

 resisted corrosion in the sea fo]' a lon<^er time than 12 

 months, and even after six months the corrosion Avas, in 

 some eases, so o-reat that it was difficult to read the 

 number. Tho later labels obtained were made of thicker 

 and harck'r In-ass, and have been quite satisfactory. 



I'he p-reat majority of the fish marked have been 

 phi ice. A dozen soles were marked and liberated, but I 

 did not reo-ard the method as suitable for this fish and no 

 moic were dealt witli. Xoiie of these soles has been 

 i-cliuncd. A few otlier fishes were also marked, and out 

 of four (hibs so tn-ated one has been returned. Tlie only 

 tiouiiih'r marked lias also been re-cauf]flit. There is no 

 reason why these maiking- ex])eriments should be 

 restricted to plaice and Honnders, but it must be said that 

 the difHculties of markin<i^ other fishes are very much 

 o-reater, and suitable .methods will take some time to 

 devise. 



It was hoped tliat 1,000 hsh wf)uld be marked before 

 tlie end of 1905, but the stress of other work interfered, 

 and I wo or three trij)s were abandoned because of 

 unsuitable weather. 



I p'ive below a summary of the experiments made up 

 to the t-nd of 100-3, and of tlie results obtained. 



If p-ivos me preat })leasure to acknowledg'e the 

 assistance icceived from all Avho have been asked to 

 co-o])erate in these experiments. IJoth Dr. Jenkins and 

 Cajitain Wiffnall have fjiven me every facility which was 

 possibh', and have becMi most kind. A\'e arc ^reatlv 

 indebted to those wlio have returned marked fishes.. The 

 Officers of the Comjnittee, Messrs. Wright, Gardner, 

 Eccles, Jones, Pritchard and Williams, have given all the 

 assistance possible. Several Members of the Committee,
