the evolving relationship of medicine to surgery in the nineteenth century
If one of these caterpillars is irritated, it will bend back its head and shoot out a curious forked organ from the segment just behind the head. This osmeterium, as it is called, is yellow and is forced out by muscular action and by the pressure of the blood; at the same time a sickly over-powering odour of lemons is given off — the smell has also been likened to that of rotten pineapples... Most of the cocktail ants are tree dwellers, making their nests under the bark, in hollow branches, or in carton nests attached to the branches. The carton nests are more or less spherical in shape, black, and they vary in size according to the size of the colonies. They are made of chewed vegetable fibres mixed with the secretion of the maxillary glands of the workers, which blackens the material and acts as a cement. The walls are thin and papery and the interior consists of irregular cells, like a coarse sponge. If the wall of one of these nests is broken open, the workers swarm out, with their tails in the air and their repugnatorial glands exposed..
You see likewise, that the lion, being the king of beasts; the horse, being the lustiest creature; the unicorn, whose horn is worth half a city; all these go with no more clothes on their backs, than what nature hath bestowed upon them: but your baboons, and your jackanapes, being the scum and rascality of all the hedge-creepers, they go in jerkins and mandilions.
It is also noticeable that the black diamond, No. 20, a dull and lusterless substance, is as transparent to the X-rays as the brilliants, while the diamond bortz, No. 6, is much less transparent than either, though more so than the imitation, No 19.
