he did was to call upon Dick. They saw much of each 

 other during the three years that the young surgeon's 

 studies continued. He accompanied Dick in his walks. 

 " I remember," he says, " that he took me one day to a 

 small pond, where he had found that curious little crus- 

 tacean, with a bivalve shell, the Cypris. This little 

 animal was of great interest to us both, as it is supposed 

 to be allied to Estheria a fossil not uncommon in the 

 Caithness flagstones. It was formerly thought to be a 

 bivalve mollusc related to the little Cyclas of our 

 rivers." 



Dr. Meiklejohn took his degree in 1854, immediately 

 after which he was appointed to H.M.S. " Harrier," which 

 was about to sail for the Baltic, during the war with 

 Russia in the same year. While in the Gulf of Bothnia, 

 Dr. Meiklejohn sent Dick a long account of the Natural 

 History of Finland. "I cannot," he said, "give you 

 any elaborate details, as my only opportunities of in- 

 vestigating the coasts were, when I accompanied par- 

 ties of armed men in boats, looking for ships, fre- 

 quently with a live shell by my side, and in danger of 

 being picked off by a Russian rifleman." After the war, 

 the " Harrier " left Portsmouth for Rio Janeiro and 

 Perriambuco, cruising along the coast ; and Dr. Meikle- 

 john again furnished Dick with a long account of the 

 botany and zoology of the lands which he had visited. 



Dr. Brown first made the acquaintance of Dick while 

 on his way from the Orkneys to Edinburgh, where he 

 was studying medicine. He called upon Dick at his 

 bakehouse, and the two had much pleasant conversation.
