220 THE GEOLOGICAL SUEVEY 



(and man of business), you may be glad to hear the reasons for 

 my preference ' — and to the man of business rather than to 

 the affectionate grandfather sets forth their mutual suitability, 

 her industry, energy, education, good principles and scientific 

 sympathies, her literary helpfulness, for * she is much cleverer 

 than I am.' But enough of ' reasons ' ; there was another 

 and more personal side to all this, and if he should not speak 

 of it, the sister friend might perhaps speak more warmly, so 

 * for the rest I must refer you to my sister Elizabeth.' 



The high-stepping Johnsonese chosen by Sir William 

 for discussing * Joseph's attachment and his prospects ' with 

 Dawson Turner is irresistible. * I beheve,' he writes, * Miss 

 Henslow to be an amiable and well-educated person of most 

 respectable, though not high connections, and from all that I

 wished, with a view to the future. 



On April 17 he went to Cambridge for a fortnight to see a 

 collection of coral plants from Australia ; then after a few 

 days with Berkeley ^ the mycologist at Oundle, proceeded on 



^ The Rev. Miles Joseph Berkeley (1803-89) as a botanist devoted himself 

 to the Cryptogams. He wrote the volume on Fungi in Smith's EriglisK Flora, 

 1836, Outlines of British Fungology, 1860, and a Handbook of British Mosses, 

 1863, besides an Introduction to Cryptogamic Botany, 1860. The collections of 

 fungi made by Darwin and other travellers came to him for description. His
