dcnce, as to the possession or conservation of the vital 

 principle. If different parts of the insect be held over 

 sulphur, it makes no difference as to the time when 

 contractility ultimately ceases, nor does the partial applica- 

 tion of heat, or prussic acid, affect that result in any con- 

 spicuous degree ; whereas when the same insects are ex- 

 posed to a very slight general heat, no part of the body 

 being protected, they die almost instantly. To revert to the 

 mere position of this ganglion being the same which brain 

 occupies elsewhere, I suppose nobody would ever have 

 thought of instituting a serious argument from that fact, 

 nor have dreamt, on that account, of advancing for gan- 

 glion No 1, a claim to more cerebral attributes than No. 2, 

 had it not happened to send off, where an organ of vision 

 really exists, the optic nerves. But these nerves must be 

 inserted somewhere into the general nervous matter of 

 the body, and that point would naturally be as near as 

 possible to the eyes ; and when it is added that worms 

 and caterpillars have no eyes, and so are destitute of even 

 this narrow pretension to a brain, or cerebroei'd ganglion, 

 it would appear that nothing could well be more gratuitous 

 than the speculation that the first ganglion is to be re- 

 garded as ihe brain of insects. 



Or take the other view, and make the extreme gan- 

 glion but one of several brains ; the inevitable conse- 

 quence of having more than one brain, more than one 

 seat of sensation and intelligence, must surely have 

 been overlooked in such an extravagance I for do not 

 sensation, and consciousness that we have it, make up our 

 individuality ? and would not a plurality of seats for these 

 faculties in the same creature disintegrate that creature, 

 and make many individualities, out of, or within one or- 

 ganisation ! * Are the pieces of a worm then, just so many 



The raighly serpcnl love. 

 Cut by this chance in pieces small, 

 In all still lived ; each little broken part 

 Felt the whole pang of all the heart. COWI.EY.
