the fact that he graduated as M.JB. at the London University, and 

 acted as one of Fergusson's house- snrgeons. His uncle, Mr. Thomas 

 Bell, the eminent zoologist, was one of the few highly trained dental 

 surgeons of his day, and induced his nephew to join him in partner- 

 ship, as also in the conduct of the dental department of Guy's 

 Hospital. The foundations of his fortunes were thus laid, to the 

 detriment, it must be feared, of his work in science. Immersed as 

 he was in practice he still found time to interest himself in scientific 

 pursuits, and was an active member of several societies, medical and 

 other. 



He was also the author of a paper in the 1 Philosophical Transac- 

 tions ' on the tJ Structure and Growth of the Tooth in Echinus," and 

 in 1863 became a Fellow of the Royal Society. He had become a 

 Fellow of the Linnean Society in 1853. 



His work 'Dental Pathology and Surgery,' 1874, at once secured 

 him a leading place, but the time expended in its preparation had 

 been so great that it is to be feared that the work was hardly issued 

 before it was out of date * 



Salter had a good general knowledge of botany, and it is to him 

 that we owe the discovery of a fact the full significance of which is 

 not worked out yet. This consisted in the discovery of perfectly 

 formed pollen grains within the tissue of the nucellus of the ovule, 

 as recorded and figured in the ' Transactions of the Linnean 

 Society,' vol. 24, 1863, p. 143, pi. 24. Whether the megasporange was 

 developed or not, we do not know, nor what were the precise cells 

 engaged in forming pollen grains in this extraordinary position. It 

 is to be hoped that some future investigator may be able to supply 

 information on these points. That the condition is not confined to 

 passion flowers we know from having seen a like state of affairs in 

 Rosa canina. 



On quitting his profession, Salter retired also from London life 

 into the country, where he occupied himself with rural pursuits and 

 horticulture, and amused himself with heraldry and archaeology. 



Personally, he was most amiable, and so stocked with general 

 knowledge that he was a delightful companion and ready to afford 

 help where help was needed. He married late in life, but his wife 

 predeceased him by a year or two. He died March, 1897.

* This, his only book, was rather the expansion of the writer's notes and experi- 

 ences over a long series of years than a complete systematic treatise on the subject, 

 and so had a kind of personal character. And although, after the manner of so 

 many of the scientific writers of that day, he sometimes plunged into warm con- 

 troversy, and not always, as things Lave turned out, on the right side ; yet his 

 work remains of solid value as a record of original and thoughtful observation, and 

 as such is still frequently quoted in the text-books of to-day. C. S. T.
