There should still be the tertiary larva, of which I see not a trace. But, on taking a needle and gradually breaking the envelope of the pseudochrysalis, after soaking it awhile in water, I see it dividing into two layers, one an outer layer, brittle, horny in appearance and currant-red; the other an inner layer, consisting of a transparent, flexible pellicle.
Bates, now in the possession of William Wilson Saunders, Esquire. The insect was not enveloped in any pellicle, nor had the cell been closed in any way; the wings were crumpled up at its side, as is usual in Hymenopterous insects which have not expanded them, proving satisfactorily that it had never quitted the cell, and that Trigonalys is the parasite of Polistes.
If a mixture of filtered potato starch paste and erythrodextrin is dried in a watch glass covered with a thin pellicle of collodion, and a drop of iodine solution placed on the latter, it penetrates very slowly through the pellicle, the dextrin becoming first tinctured with red, and the granulose afterward with blue.
The grand old Mosibe, a tree yielding a bean with a thin red pellicle, said to be very fattening, had probably seen two hundred summers. Dr. Kirk found that the Mosibe is peculiar, in being allied to a species met with only in the West Indies. The Motsikiri, sometimes called Mafuta, yields a hard fat, and an oil which is exported from Inhambane.
For, as Gilbert tells us, when the heart is compressed this pellicle is also compressed, and if any moisture is found beneath the pellicle it is expressed into the substance of the lachrymal gland by the constriction of the heart, and men in sorrow therefore shed tears. Accordingly, men who are too joyful shed tears.
This plan prevents the rising to the surface of that coat or pellicle which contains some of the most valuable properties of the milk. I have already said that it was as necessary that the stomach should have rest as any other muscular organ. Some writers say that the infant should be kept perfectly quiet, at least half an hour, after each meal.
This certainly would be the case, were it not that the young fruit, encased in a soft green husk, with the incipient meat adhering in a jelly-like pellicle to its sides, and containing a bumper of the most delicious nectar, is what they chiefly prize. They have at least twenty different terms to express as many progressive stages in the growth of the nut.
It will immediately begin to turn sour; it should therefore be covered with a cloth, and kept moderately warm. A pellicle will be formed on the surface, beneath which the vinegar acquires strength: it must be kept standing for a month or two, and then put into a cask. The bunghole should be left open, and the vinegar will soon be fit for use.
When nitric acid, diluted with four parts of water, is added drop by drop to the milk expressed from a very young fruit, a very extraordinary phenomenon appears. At the centre of each drop a gelatinous pellicle is formed, divided by greyish streaks. These streaks are simply the juice rendered more aqueous, owing to the contact of the acid having deprived it of the albumen.
The most nearly complete instances that I have seen furnishes me with the following data: the pseudochrysalis is very closely enveloped in the skin of the secondary larva, a skin consisting of fine transparent pellicle, without any rent whatever. This is the pouch of the Sitaris, save that it lies in immediate contact with the body enclosed.
