In the ^ Catalogue of Microscopic Objects ' in the cabinet of your 
own Society, published in 1864, the preface states that, "What was 
proposed, and has been attempted, is — avoiding any attempt at 
scientific arrangement — to provide an index to the slides, with their 
titles, as nearly as possible, in alphabetical order. The exceptions 
to a strict adherence to this order are : — 
" 1. Some groups of objects are entered under a common head, 
as Diatomaeese, Shell, 'Wood, and a few others. 
" 2. The slides of a series presented are entered as numbered 
when received, though in adhering to that arrangement the alpha- 
betical order of the titles is disregarded; thus, under the title 
Shell, the series of slides (illustrating its structure) presented by 
Dr. W. B. Carpenter are entered as numbered, his arrangement 
(for which there were no doubt good grounds) being preserved." 
Then follows some remarks on the Diatoms which are grouped 
alphabetically as a. — species ; P. — locality ; y. — sundries. 
There was a Microscopic Soiree given by the Bath and Bristol 
Microscopic Societies during the meeting of the British Association 
at Bath in 1864. The synopsis issued on that occasion is so
