The dorsal surface of the Slater is united to the larval skin a little behind the head. At this point, when the union has been dissolved a little before the change of skin, there is a foliaceous appendage, which exists only for a short time, and disappears before the young Slater quits the brood-pouch of the mother. Maggot-like larva of Ligia, magnified 15 diam. R remains of the egg-membrane.
He would have marked the long trains, packed with men or piled with great guns and war material, creeping slowly, alert for train-wreckers, along the north-going lines; he would have seen the Scheldt and Rhine choked with shipping, and pouring out still more men and still more material; he would have noticed halts and provisionings and detrainments, and the long, bustling caterpillars of cavalry and infantry, the maggot-like wagons, the huge beetles of great guns, crawling under the poplars along the dykes and roads northward, along ways lined by the neutral, unmolested, ambiguously observant Dutch.
The bigger the animal, the greater his ambition appears to be to climb to the highest summit; and when a huge, slimy beast has with infinite squirming attained a solitary peak, he does not tire of raising his sharp-pointed, maggot-like head, and complacently looking about him.
The food supply consists of plantain, yam, koko, sweet potatoes, maize, pumpkin, pineapple, and ochres, fish both wet and smoked, and flesh of many kinds including human in certain districts snails, snakes, and crayfish, and big maggot-like pupae of the rhinoceros beetle and the Rhyncophorus palmatorum. For sweetmeats the sugar-cane abounds, but it is only used chewed au naturel.
We might urge that, according to this proposition, provisional organs as the first produced must exceed the later-formed permanent organs in importance. But let us stick to the Crustacea. In Polyphemus Leydig finds the first traces of the intestinal tube even during segmentation. In Mysis a provisional tail is first formed, and in Ligia a maggot-like larva-skin.
Nauplius-brood. Ord. 1. Ceratometopa. Nauplius with frontal horns. Ord. 2. LEIOMETOPA. Nauplius without frontal horns. Sub-class II. HEMISCHISTA. Segmentation not complete. A. Nototropa.

Brown ant-like creatures, white maggot-like creatures, of several shapes and sizes, were hurrying up and down, as busy as human beings in Cheapside. They were Termites, 'white ants' of which of the many species I know not and the lump above was their nest.
We may see, without further discussion, how the representation given by Claus of the development of the Copepoda may pass almost word for word as the primitive history of those animals; we may find in the Nauplius-skin of the larvae of Achtheres and in the egg-like larva of Cryptophialus, precisely similar traces of a transition towards direct development, as were presented by the Nauplius-envelope of the embryos of Mysis and the maggot-like larva of Ligia, etc.
