Mr. Garner on the Nervous System of Molluscous Animals. 501 
haps bearing a resemblance to a spine. These two distant fasciz offer but a 
poor resemblance to the spinal chord of many fishes: but in reality some of 
them, as Lophius, Tetraodon and Petromyzon, appear (from the description of 
authors*) to have that organ scarcely better developed; and a disjoined 
state is shown to be the normal condition of this organ in its first stage of 
development. 
In concluding this paper, the author is conscious how much must be dry 
and uninteresting to many. As, however, he believes there are some new facts 
in it which may assist future inquirers, who may endeavour to show there is 
some meaning and method in these parts, and as he thinks he has proved the 
opposite to what another author on the nervous system affirms of these 
organs in the Mollusca, viz. that they ought in every respect to be considered 
below those of insects, he will conclude by claiming the indulgence to which 
the difficulty of the subject entitles him.
