Infusoria. It is curious, however, to note that a number of 
them in a tumbler produced in the light a large crop of bubbles 
of gas after the fashion of submerged plants. There was 
not, however, much appearance of chlorophyll to account for 
this. I regret it was not tested to determine its nature, 
which I supposed at the time to be oxygen. This organism 
was considered to be a plant, at all events as recently as the 
date of the third edition of the Micrograpliical Dictionary, about 
nine years since, and I for some time looked for it amongst 
the algae. I sent specimens to some of my friends for deter¬ 
mination, but in no case did they bear the shaking undergone 
in carriage, having, though sent in considerable numbers, 
entirely disappeared in a short time. I took, however, no 
precautions, except filling the bottles quite full. The figure 
in Saville Kent’s great work is correct, but hardly doing it 
justice and wanting in details. I observed numerous double 
specimens, the shape of a short old-fashioned silk purse, and 
which seemed to swim as freely as the globular single families. 
Whether this is a species frequently met with or not I do 
not know ; not being so beautiful as Volvox globator, it may 
not receive a comparative meed of notice ; but, at all events, 
it seemed to me that its occurrence in countless millions, 
as in the present case, and the singular effects produced 
thereby were worthy of record.
