The Life of the Spider bull's snout, that seems carved out of a block of crystal? Would you behold the Flesh-fly, the common Blue-bottle, daughter of the maggot, as she issues from the earth? Listen to our author:

'She disjoints her head into two movable halves, which, each distended with its great red eye, by turns separate and reunite. In the intervening space a large glassy hernia rises and disappears, disappears and rises. When the two halves move asunder, with one eye forced back to the right and the other to the left, it is as though the insect were splitting its brain-pan in order to expel the contents. Then the hernia rises, blunt at the end and swollen into a great knob. Next, the forehead closes and the hernia retreats, leaving visible only a kind of shapeless muzzle. In short, a frontal pouch, with deep pulsations momentarily renewed, becomes the instrument of deliverance, the pestle wherewith the newly-hatched Dipteron bruises the sand and causes it to crumble. Gradually, the legs push the rubbish back and the insect advances so much towards the surface.' 18
