35O The Naturalist of C umbrae. 



Robertson's name is similarly mentioned, but it may 

 be well to refrain from quoting them all, since it is 

 not absolutely certain that all the readers of this life 

 will either be or intend to become enthusiastic rhizo- 

 podists, and those who are lukewarm on the subject 

 may ignorantly fancy that Latin names of five, six, or 

 seven syllables are out of proportion to the merits of 

 organisms perhaps onlya twentieth of an inch in length. 



Turning to another branch of the animal kingdom, 

 the entomostraca, in another work of first-rate im- 

 portance, we again find the name of Robertson re- 

 peatedly occurring. 



In the years 1878 and 1880, Dr. George Stewardson 

 Brady, F.R.S., brought out his "Monograph of the 

 British Copepoda," published by the Ray Society. 

 In the Introduction, while pointing out the advantage 

 of searching for these little crustaceans in the dusk 

 or after dark, Dr. Brady says : 



" Some of the pleasantest and most profitable hours 

 which I have ever spent have been when, after a day's 

 dredging, I have set out at sunset on a quiet boating 

 excursion for the purpose of capturing such prey as 

 could be got in the surface net. Many hours of this 

 kind spent in the company of my old friend Mr. 

 David Robertson, amongst the Scilly Islands, on the 

 Firth of Clyde, on the sheltered bays of Roundstone 

 and Westport, or on the stormier coasts of North- 

 umbria, will long live in my memory, not only by 

 their results in the acquisition of valuable specimens, 

 but as times of unalloyed delight in the contempla- 

 tion of nature under a different guise from that in 

 which we usually see her."
