Then, without further delay, the coat which it wears for this rough piece of work begins to split, and the larva skins itself, coming out of its wrappings head first. It is then the normal larva; the only form known to Réaumur. The rejected coat forms a suspensory thread, expanding at its free end to form a little cup.
The Mercury was at times 50° below the freezing point of Farenheit, and 22° below that of Reaumur. All out-door labor was suspended, and the poor, without the wages of labor, were, of course, without either bread or fuel.
We shall only dwell upon the first, because it is the only one interesting to the distiller. The areometer can only be just, when the atmosphere is temperate; that is, at 55° Fahrenheit, or 10° Reaumur.
There is no nonsense about it; you could not indulge in vapours and the finer sentiments in the midst of its deadly earnest if you tried. The thermometer goes down to twenty degrees of frost Reaumur, and down you go with it to the realities, to that elementary state where everything is big health and sickness, delight and misery, ecstasy and despair.
Very often as the Cigale is absorbed in her maternal task a diminutive fly, also full of eggs, busily exterminates the Cigale's eggs as fast as they are laid. This insect was known to Réaumur. In nearly all the twigs examined he found its grub, the cause of a misunderstanding at the beginning of his researches. But he did not, could not see the audacious insect at work.
The ambuscade of the Ant-lion is classic; it does not differ greatly from the others. He excavates a conical pitfall, in which he conceals himself, and seizes the unfortunate ants and other insects whom ill-chance causes to roll into it. See e.g. Tennent, Ceylon, vol. i. p. 252. Also Réaumur, Mémoires pour d'histoire des Insectes, t. i. p. 14, and t. vi. p. 333. The baited ambush.
But if we turn to pathology, it offers us some remarkable approximations to true Xenogenesis. As I have already mentioned, it has been known since the time of Vallisnieri and of Réaumur, that galls in plants, and tumours in cattle, are caused by insects, which lay their eggs in those parts of the animal or vegetable frame of which these morbid structures are outgrowths.
As to the climate, the difference between the heat at two hours afternoon in the month of the vernal equinox, and at an hour before sunrise, has been as great as ten degrees of the thermometer of Reaumur, as I have been informed by one of the medical staff attached to the army, who was in possession of that instrument.

"I do not contravene that assertion," was his quiet answer. "And at this stage of our journey, according to all known laws on the increase of heat, there should be here a temperature of <i>fifteen hundred degrees of Reaumur</i>." "There should be you say, my boy." "In which case this granite would not exist, but be in a state of fusion."
