DIATOMACEA, 41 
when exposed to the light. This wonderful movement I had 
the pleasure of witnessing with CuarLes Kinasiey at Caprain 
Busy’s house, when we had a fresh gathering under the 
microscope. 
As a matter of history I may here state that our Society, in 
1872, was only just established, and wanting a device for its 
seal; this lovely specimen, found in our Dee, seemed most 
appropriate ; and encircling, as it does, the monogram of our 
first President, it constitutes a fitting and perpetual memorial of 
his presence amongst us. But we must go further back than 
1872 if we would do honour to the discoverer of Hucampia. 
We have amongst us one who has been through life a minute 
and industrious observer in the fields of Nature, and it was in 
one of Mr. Joun Price’s note-books, dating back as far as 
1845, that the Hucampia was figured as found by him, with 
other objects of interest, in the Estuary of the Mersey. This 
was twenty-nine years before it was again found in the Dee, 
and eleven years before W. Smiru figured and described it in 
his ‘* Synopsis of British Diatomacex”’ ; and then he had only 
seen the Eucampia as taken from the stomach of a Pecten. 
NotE.—n. sp. indicates that the species were new at the 
time of the publication of ‘* Smith’s British Diatomacee’”’ and 
“« Gregory's Diatomacee of the Clyde,’ but being now well 
established they ought to be accredited to Sm. and Greg.
