292 The Scottish Naturalist. 



Shetland Islands ; and on the return journey went with him to the 

 Durness limestone. Sir Roderick in a paper, read in the same 

 year at the meeting of the British Association in Leeds, drew at- 

 tention to the importance of Peach's discovery as giving a clue to 

 the age of the strata ; though the true succession of the formations 

 was misinterpreted by him and by most geologists, owing to causes 

 that have been finally rendered clear in the controversy above re- 

 ferred to. 



On Mr. Peach's retirement in i86i,the change rendered him 

 very seriously ill ; but after a time he recovered, and applied him- 

 self with vigour to his favourite pursuits. He shared in Gwyn 

 Jeffreys' dredging voyages to the Shetland Islands, and collected 

 the Polyzoa. x\fter his removal to Edinburgh, he made valuable 

 discoveries among the plant-remains of the strata of the Lothians 

 and Fife. For a time he was President of the Royal Physical 

 Society of Edinburgh ; and in 1871-74 he was presented with the 

 Neill prize, in the gift of the Royal Society of Edinburgh, in recog- 

 nition of his discoveries, and of the addition by his labours of 

 about 20 species of Echini, Medusce, and Sponges to the Biitish 

 fauna. In 1868 he was elected an Associate of the Linnean 

 Society. His published scientific papers have been numerous and 

 valuable. He died in Edinburgh on 28th Feb. 1886, in his 86th 

 year, leaving a son, Mr. B. N. Peach, well known for his work in 

 the Geological Survey of Scotland, and for his papers on Geology 

 and Paleontology. 



Thomas Edward is a name widely and honourably known, 

 thanks to the biography by Dr. Smiles ; which is read, not only in 

 English-speaking countries, but also in translations into more than 

 one European language. The history of his life teaches, like that 

 of C. W. Peach, how true it is that the progress of science can be 

 advanced, and the most unfavourable conditions overcome, and even 

 turned to account, by ability and resolution. In many respects 

 these two men resembled one another. In the strength of their 

 love for all the productions of Nature, and in their excellence as 

 observers, as well as in the width of their investigations, they were 

 much alike. Though Peach's discoveries were largely made in 

 the strata of the earlier geological formations, and comparatively 

 little among land animals and plants, while Edward's related 

 in great part to the latter groups, yet they both made im-
