importance was that which he carried out in partnership with Canon Norman 

 on " The Marine and Freshwater Ostracoda of the North Atlantic and of 

 North-Western Europe/' the first part appearing in 1889, the second in 1896. 

 In this he gives a signal example of his scientific ingenuity which is worthy 

 of additional record. He points out (p. 622) that " In consequence of the 

 small size of Ostracoda it is extremely difficulty to procure spirit-preserved 

 specimens from the deep sea, and although the Myodocopa, being much larger 

 than the Podocopa, would be detected by the experienced eye of a Carcino- 

 logist who had studied them, yet the Zoologists usually attached to Govern- 

 ment Expeditions cannot be expected thus to notice them. Hence it is that 

 in a large number of cases the only examples which have come into our 

 hands are such as have been picked out of dried material. It struck us that, 

 notwitstanding their dried condition, it might yet be possible by maceration 

 to get some idea of the withered inmates of the shells. We therefore made 

 experiments, and succeeded in restoring the animals beyond our most ardent 

 expectations. All the portions of the animals figured [in several genera and 

 species mentioned] have been taken from dissections of animals which have 

 been preserved in a dried state for very many, in one case, as long as twenty- 

 three years, and we are satified that these drawings will be found to be 

 almost as exact, so far as they go, as those taken from spirit-preserved 

 examples." 



In 1884, when the editing of the " Challenger " Keports had passed into the 

 vigorous hands of John Murray, the eighth volume of Zoology appeared, having 

 as its opening treatise Brady's Eeport on the Copepoda illustrated by fifty-five 

 carefully drawn plates. Though the collection thus laboriously discussed 

 presented many points of interest, Brady was forced to admit that it was far 

 from representative of what the ocean's resources were likely to contain, and 

 that the last word had not been said as to methods of preserving these 

 organisms. In his Introduction he makes some remarks which bear on a 

 subject previously mentioned: — "The appearance of these minute creatures at 

 the surface depends upon conditions, the nature of which we scarcely at all 

 understand. Night, on the whole, seems to be more favourable than daytime, 

 but even during the day they sometimes appear in numbers so vast as to 

 colour the sea in wide bands for distances of many miles. This appearance 

 has been noticed, perhaps, most frequently in the tropics ; but even in the 

 Arctic seas some species, especially Calanus (Cetochilus) finmarchicus, are at 

 times so abundant as to constitute, it is said, a most important item in the 

 food of the whale. So far, indeed, as number and size of individuals are 

 concerned, it would appear that the cold water of the Arctic and Antarctic 

 seas are even more favourable to the growth of Copepoda than the warmer 

 seas of the Tropics." 



With his frequent and arduous contributions to scientific literature Brady 

 combined, from 1857 till about 1890, the conscientious exercise of an exacting 

 profession, practising as a doctor in Sunderland, " and after that gave up his 

 time to his professorship at the Armstrong College, until he resigned in 1906
