Archee — On Freshwater Rhizopoda. 67 
the day will come — if indeed it have not come already — when England 
shall be known less as the country of Marlborough] and of Cecil, than 
as the country of IS'ewton and of Shakspeare. 
Let us work then earnestly, brayely, faithfully, to promote the 
great objects for which we were instituted, yet not without a thought 
that we are an Irish Academy ; remembering that when we labour in 
the cause of Literature or Science, we labour too for the honour of our 
country ; remembering for her sake, if not for our own, that for the 
faithful worshipper of Truth, Truth has her own rewards, illuminating 
his brow with some portion of her own splendour — some pale reflexion 
of the glories that surround her throne.

On a former occasion, and in another place, I brought before the 
notice of those interested in types of existence so lowly, a series of 
forms in certain groups of E,hizopoda, at once novel to our fresh waters, 
as well as some of them possessing in themselves a considerable interest 
as connecting links, leading on to their more complex and structurally 
more differentiated marine relatives. Having, since then, continued 
to bestow some attention to the subject, I venture to propose to bring 
forward from time to time, as opportunity may offer, such casual 
jottings, or accounts of any few additional new forms, as good fortune 
may enable me. 
In bringing forward those I was able to present in my former 
communication, owing to their heterogeneous nature and their positive 
and negative characters inter se I experienced a difficulty in endeavour- 
ing to put them before the reader in anything like a '^natural" 
sequence. In this, and any further communications I may be able to 
make, my difficulty alluded to is removed, while the disadvantage 
remains ; for I must just submit to take them in such order as 
accident and opportunity may present them, irrespective of any 
mutual affinities ; and, indeed, this is the less to be regretted, for 
as yet the freshwater forms, or rather the types they represent, are too 
few, and their characters too negative, to be able satisfactorily to 
relegate them to established Classes and Orders. I^ot indeed possibly 
do the freshwaters really possess forms calculated to fill up the intervals 
or lacunae between certain therein existent and already recorded
