ganic beings. As by a catenation of obvious and palpable 

 facts we can trace back the history of this world to a state of 

 fusion, if not of general nebulosity, so are we warranted in 

 anticipating its future congelation, when old age shall have 

 come over it as barrenness, and the gases shall have solidified 

 by intensity of cold; when, it may be, the sun himself shall 

 have grown dim, and nature, in so far as this system is con- 

 cerned, have sunk in years ; when the stupendous cycle shall 

 have been accomplished. Then, and with humble reverence 

 let the mighty acts of Supreme Omnipotence be spoken of, 

 it may be that the eternal and ever-glorious Being which 

 willed matter into existence shall pronounce on it the final 

 doom of annihilation ; and 



"the great globe itself 



shall dissolve, 

 And, like the baseless fabric of a vision, 

 Leave not a rack behind." 



Or, what is far more probable, to judge from the universal 

 analogies of all that is within our grasp, its elements shall 

 again be called forth into light and life, and blaze forth the 

 recommencement of the same system. 



It is inconsistent with our notions of divine benevolence, to 

 suppose that the human race shall be suffered to linger here 

 upon earth, till such secondary causes as we have been con- 

 sidering should suffice to gather the last man to his fathers.

Art. VII. Description of some singularly formed Orthopterous 

 Insects. By George Robert Gray, Esq. 



Cylindro^des G. R. Gray. 

 Head small, of a long triangular shape, with the angles 

 rounded. Antennae (only a few basal joints remained in the 

 specimen) apparently moniliform. Labrum small, shaped like 

 a horseshoe. Mandibles small, strongly dentated. Eyes very 

 small. Palpi with the last joint truncated, somewhat rounded, 

 and slightly enlarging towards the tip. Body very long, cylin- 

 drical ; the thorax occupying more than a third of its whole 

 length, distinctly dividing into prothorax, mesothorax, and 

 metathorax. The first is the longest, and cylindrical; the 

 last two are nearly equal. Abdomen of eight joints, the last 

 the largest, with the apex rounded, depressed and margined 

 above, and without any caudal appendages. Anterior legs 

 moderately strong, compressed and dentated in front; the tarsi
