MEMOIR OK THE LATE FREDERIC KITTON. 
It was at this time that I made his acquaintance, and his valued 
friendship remained to me to the end. I had the pleasure or 
spending a morning with him some two months before his death, 
and though finding him sadly altered, I did not anticipate that 
I should see him no more. 
In the thirty years between 1855 and 1885, he was associated, 
more or less, with all the Societies in Norwich which had for their 
object the increase of knowledge, and in all he was valued ; but 
I fear that as his own special study was one that could not be 
generally appreciated, scarcely any one realised that we had in our 
midst one whom the learned in other parts of the kingdom and in 
far distant countries “ delighted to honour,” for he was an honorary 
member of both the Eoyal Microscopical and Quekett Societies in 
London, and a corresponding member of the New York, Belgian, 
and Dublin Societies. An illustration of how easy such ignorance 
is, I may mention that he once told me with what surprise he learnt 
himself that the eminent Swedish Diatomist, P. T. Cleve, of Upsala, 
with whom he had long corresponded, had come to England, not on 
the subject of their mutual interest, hut to receive the honour of the 
honorary membership of the Chemical Society. 
About 1881, he published sets of 100 slides each, to illustrate 
the Diatomacete of the County of Norfolk; these were neatly 
packed in four-rack cases, bound as 8vo. books. His lists of the 
order for the county will be found in your ‘ Transactions,’ vol. ii. 
p. 33G ; and vol. iii. p. 754. 
He was able to read aird translate any scientific papers which 
were published in French, German, or Danish, and he had also some 
acquaintance with the Anglo-Saxon language and literature. It is 
only necessary to read his Presidential Address to yourselves, or 
some others of his papers read in Norwich, to learn how much he 
knew of English literature. 
He was of most retiring and simple manners, but with any one 
with whom he was well acquainted, of a most genial disposition. 
Such of his friends were always welcome at the shop in the 
Haymarket, and many a pleasant and instructive evening hour have 
I spent there with him. 
First and last he must have mounted many thousands of slides, 
and he left in his own cabinets about 5000, though many of these 
were presents or exchanges. About 4000 slides referred to the
