[spent a day with Dr. Schmarda. To a person 
primed with general knowledge in-Marine Zoology, 
the extent and value of his labours are seen at a 
slance. Since Broussonnett’s visit to the island, we 
have had no naturalist who has done so much, or 
who has done what he has accomplished so effectus 
ally, in the oceanic department, as Dr. Schmarda. 
£ would not undervalue Dr. Bancroft’s collection, or 
Dr. Parneil’s, both important acquisitions to the 
British Museam; nor Mr, Gosse’s delightful memo- 
randa in his * Naturalist’s Sojournin Jamaica ”— 
But besides fishes, Dr. Schmarda has attended to 
the infusoria, the radiata, mollusca, and crustacea, 
and greatly enlarged our acquaintance with the 
most numerous, and most varied objects of marine 
life. His glass cylinders of about the length and 
breadth of a spermaceti candle, are exceedingly 
convenient and effective deposits for specimens. A 
paper marked with the object deposited, shoved in 
between the several specimens, separates each from 
each, and enables one, in the colourless glass and 
liquid to inspect them all round. Drawings could 
be made without removing the animal, and descrip- 
tions noted without handling the specimens. 
In the facilities of transport, which the ocean 
waters afford, Dr. Schmarda finds the living crea- 
tures in the lower grades of organic life not alone
