mj'- experience at Dunbar in former years, when it was found that plaice 

 and dabs kept in small tanks lost weight in winter and gave up feeding.* 

 In tank No. 1, which contained as we have seen about 185"5 gallons 

 (842 '5 litres), seven whitings, five codlings, one haddock, one common 

 dab, and one sand-eel were placed ; the latter soon disappeared, and was 

 probably eaten. The fish were measured on two occasions, (1) at an 

 interval of 100 days, and (2) after 155 days. It would, as it turned out, 

 have been better to have aieasured them more frequently, since, with the 

 exception of the sand-eel, all the fishes survived in this tank; but from the 

 mortality in the other tanks it was deemed advisable to disturb them as 

 little as possible. In measuring them, they were first transferred to 

 convenient dishes, seized cautiously with a loose cloth, and when laid on 

 the measuring board care was taken to free the under surface of the fish 

 from the cloth. A little practice made the process easy, the only forms 

 requiring extra care and promptness being the haddocks. In the 

 accompanying Table I give the particulars regarding these fourteen fishes 

 which were kept in water at the ordinary temperatures.
