Neoptolemus

“ Serve some poor churl who drags his days in grief,
Than the whole lordship of the dead were mine."
Such was the immortality to which Paganism condemned even its best and bravest.
One touching inquiry both Agamemnon and Achilles put to their visitor from the upper world. How fare their sons? Where is Orestes?—asks the great king. Did Neoptolemus, in the later days of the war, prove himself worthy of his father?—inquires Achilles. When he has been assured of this, the shade of the mighty hero, well satisfied,
"Passed striding through the fields of asphodel." ”

“ It is related that Neoptolemus, the general of Mithridates,2709 defeated the barbarians during summer-time in a naval engagement in this very strait, and during the winter in a cavalry action. They say that about the Bosphorus the vine is hidden away in the earth in winter, great mounds of mould being piled over it [to preserve it from the frost] . They also report that the heats are excessive, [this may be accounted for in several ways,] perhaps men’s bodies not being accustomed to them, feel them the more; perhaps the plains are at that time unrefreshed by winds ”

“ Deep-sea cold seeps and hydrothermal vents are both characterized by low nematode diversity and high dominance of single species. The low genera and species richness can be explained by the harsh physico-chemical conditions present in both ecosystems. There is no unique affinity with seeps or vents at genus level, suggesting a lower taxonomic level of endemicity for nematodes compared with mega- and macrofauna. Dominant nematode genera varied among the different seeps and hydrothermal vents. ”

“ Nematode diversity at seeps and vents
Local diversity of the benthos is in general relatively high in deep-sea sediments, with low dominance and a high number of species co-existing on the same spot [60] , [61] . For nematodes it is not different: the most abundant or dominant genera, like Acantholiamus, Thalassomonhystera, Microlaimus or Leptolaimus, represent the communities for less than 20% in general, and contain many con-generic species [2] . Local species numbers can reach values higher than 100, whereas species richness often increases with densities [62] – [63] . ”

“ The similarity in nematode genus composition between vent ecosystems and control sites, stands in clear contrast with the presence of a specialized endemic hydrothermal megafauna. There is no specially adapated nematode fauna observed at vents so far. No symbionts are found, while the dominant vent genera are also present in the regular deep-sea sediments. The ephemeral nature of vents, in combination with their strongly isolated nature, possibly does not allow for the evolution and distribution of specially adapted forms, like in the macro- or megabenthic size class. ”

“ The Hyopotamus (Lign. 257) is a genus of Anthracotherioid pachyderms, two species of which have been determined by Prof. Owen (Quart. Geol. Journ. vol. iv. p. 103, &c.) , from specimens of teeth found in the upper eocene of the north-west coast of the Isle of Wight, by the Marchioness of Hastings.
The Palæotherium, Dichobune, Dichodon, Paloplotherium, and others occur in the upper eocene fresh-water deposits of Hordwell Cliff (see Charlesworth’s Journal, No. 1, p. 5, and pl. ii.; Quart. Geol. Journ. vol. iv. p. 17, and pl. iii.; and Rep. Brit. Assoc. 1851, sect. p. 67) . ”

“ Three possible reasons for the low nematode densities at vents are put forward: (1) The substrate is unsuitable for supporting high abundances. Vents consist of recently formed hard substrates, such as basalt or sulphide minerals precipitates, with no or little sediment covering the hard substrate. Vent fluid reaches the water column through sulphide chimneys or crack and crevices of basalt, on which large foundation species, such as bivalves and tubeworms, grow. Most hydrothermal vents provide living space for meiofauna only on these hard substrates, or on the associated foundation species. ”

“ The species probably occurs throughout the rocky areas in the hills and buttes of Harding County, and also frequents abandoned or little-used buildings and feed stations for livestock. All of our specimens were trapped in rocky habitats, but in many such places we trapped unsuccessfully for Neotoma cinerea, even though some sign of its presence frequently was evident. Five of our seven specimens (all taken late in June or early in July) are young of the year in grayish pelage. An adult male trapped on July 14 had testes that measured 14. ”

“ Now in the species of Hesperomys, the molar teeth are always rooted, and in the form of the skull and the lower jaw they agree with the Muridæ, and do not 77present the characters above pointed out as distinguishing the Arvicolidæ, and as regards the cranium and lower jaw, it is only in the genus Neotoma that any approach is evinced. ”

“ Moreover, I have been unable to learn that, in any instance, bones of the hippopotamus have been found in the drift of northern Germany associated with the remains of the mammoth, tichorhine rhinoceros, musk-ox, reindeer, lemming, and other arctic quadrupeds before alluded to; yet, though not proved to have ever made a part of such a fauna, the presence of the fossil hippopotamus north of the fiftieth parallel of latitude naturally tempts us to speculate on the migratory powers and instincts of some of the extinct species of the genus. ”

“ Noetling's Geological Map, in which he had marked the spot where he found the flints with No. 49. The Township Officer kindly searched in his office, but the map was not forthcoming, and all idea of locating the flints had to be abandoned, and instead we occupied ourselves in collecting Tertiary mammalian remains from the neighbourhood. Among these, however, we obtained an upper premolar of a small species of Rhinoceros, which will be mentioned hereafter in connection with the worn femur of Hippopotamus found by Dr. Noetling. ”

“ At vents, nematode densities and biomass are always low. It is likely that the presence of hard or soft substrates, the latter being more favourable for nematodes, is reponsible for the differential response between seeps and vents. Competition for food- or space with macro- or megafauna, or even the meiofauna such as copepods is possibly an additional factor responsible for the high variation at seeps and the lower numbers at vents, although evidence is lacking so far. ”

“ In answer to this enquiry, it has been remarked, that the living hippopotami, anatomically speaking so closely allied to the extinct species, are so aquatic and fluviatile in their habits, as to make it difficult to conceive that their congeners could have thriven all the year round in regions where, during winter, the rivers were frozen over for months. ”

“ I wish it to be observed, that Neuroptera, in the genera Psyche, Cloëon, Termes, Psocus and Mantispa, does not merely assume the form of the genera, Tinea, Chironomus, Formica, Aphis and Mantis, but actually possesses the characters and appearance of the classes Lepidoptera, Diptera, Hymenoptera, Hemiptera and Orthoptera. The obviously homogeneous character of Lepidoptera and Coleoptera, although, probably, containing in every sub-class more species than the whole of Neuroptera, clearly disproves the existence of variety amongst their contents, equal to that amongst the contents of Neuroptera. ”

“ Potonié describes the secondary veins of the pinnules of Neuropteris pseudogigantea [1535] as occasionally anastomosing, a feature which may be regarded as a step towards the reticulate venation of the closely allied genus Linopteris.
Renault [1536] described some petrified pinnules of Neuropteris in which the mesophyll shows a differentiation into upper palisade tissue and lacunar tissue below; the lower epidermis is infolded at intervals where grooves (probably stomatal) occur like those on the leaves of an Oleander (Nerium oleander) . ”

“ It is certainly well exemplified by this and several other species of the genus Notoreas, and it will be at once noticed by the collector, how extremely difficult it is to follow these active little moths, as they fly with short and rapid flight over the grey rocks and stones, with which their fore-wings so completely harmonize; the momentary glimpse obtained of the brilliant hind-wings so completely deceives the eye, that there is much more difficulty in marking the spot where the insect alights, than would have been the case if the brilliant colour had never been displayed. ”

“ About thirty species are known. Knowledge of the group is still very imperfect. A larva has been found of a most remarkable nature that probably belongs to it; it was described under the name of Necrophilus arenarius, and considered to be a fully-developed Insect. This larva occurs in the tombs and pyramids of Egypt where sand has accumulated. The perfect Insects of the genus Nemoptera are, however, found in open places amongst bushes, and flit about in a very graceful manner. ”

“ The neuters are much less numerous than the workers, bearing the proportion of one to one hundred, and exceeding them greatly in bulk. They are also distinguishable by their long and large heads, armed with very long tubulate mandibles. Their office is that of sentinels; and when the nest is attacked, to them is committed the task of defending it. These neuters seem to be a kind of abortive females, and there is nothing analogous to them in any other department of entomology. ”

“ This apparently different physical nature of both chemosynthetic ecosystems is therefore likely to explain lower genera richness at vents. Other possible reasons are that the coexistence of nematodes, with various other, highly abundant epifaunal organisms at vents, might result in competitive exclusion, and could explain low eveness of single nematode species, in association with low densities. ”

“ It is as if Nature had desired to do her own work in peace and without being disturbed, for fever, ague, mosquitoes, and malaria are very common. Yet a certain number of people always live in 212 such places. In France, e.g., the leeches in the great marshes near the Landes form a source of riches. Such reeds also are or were the home of the hippopotamus, crocodile, and other extraordinary animals. The extinct British hippopotamus no doubt found in the Chelsea or other marshes a home as congenial to its tastes as is the sudd of Egypt to its living descendants or allies. ”

“ The Heteroura androphora is another nematode which lives in the stomach of tritons. The male is always rolled round the body of its female. The two sexes are always free, contrary to that which is observed in the syngami. The Blattæ, coleopterous insects, also harbour sexual nematodes. Radkewisch saw two species of anguillulæ, the Anguillula macroura and appendiculata, in the Blatta orientalis, and an Oxyuris brachyura in the Blatta germanica. These eggs leave the body with the feces, and resist the action of deleterious agents. ”

“ We shall therefore only recognise one genus.
The Hippopotamus at present is African in range, and confined to that continent. But quite recently it inhabited Madagascar; and further back still in time the existing African species, H. amphibius, ranged into Europe; there were also Indian forms, which were contemporary with the Stone-age man. The Common Hippopotamus is a great thick-skinned beast with but few hairs. It has four toes on each foot, a complex stomach, but no caecum. The strong incisors continue growing through life, as do the great canines. ”

“ This connexion between Neogaea and Africa was doubtless a continuation of the old Jurassic equatorial land-belt to which allusion has been already made; freshwater fishes being probably a group of earlier radiation than mammals. Perhaps the distribution of the reptilian genera common to Neogaea and Madagascar may be explained in the same manner, although tortoises apparently identical with Podocnemis occur in the Eocene of Europe (as well as in that of Africa and India) , so that this group may have radiated from the north. ”

“ These Fishes live in marshes and lakes, fresh-water or brackish, and feed on worms and insects. Nothing is known of their breeding habits and development.
Two genera: Notopterus, with a dorsal fin and 6 to 9 branchiostegal rays—three species from India, Burma, and the Malay region, and one from West Africa; Xenomystus, without dorsal fin and with only 3 branchiostegal rays, the unique species inhabiting the White Nile and West Africa. ”

“ To the times we have just passed in review succeeded others of a very different kind, to which has been given the general naive of Neolithic. The fauna, probably lender the influence of climatic and orographic changes, underwent a complete transformation; the mammoth, the cave-bear, the megaceros, and the large felidæ died out, the hippopotamus was no longer seen, except in the heart of Africa; the reindeer and other mammals that love to frequent the regions of perpetual snow, retired to the extreme north ”

“ Consequently, with these teeth the hippopotamus can cut through the stems of thick and strong herbage as with shears, and the strength of its jaws is so great that an angered hippopotamus has been known to bite a man completely in two, and to crush a canoe to fragments with a single movement of its enormous jaws. ”

“ The mammalian remains found in Pleistocene deposits are of exceptional interest. Among the more remarkable forms are a species of hippopotamus, the elephant (including a pigmy variety) , and a gigantic dormouse. 508 In the Coralline Limestone the following fossils have been noted:—Spondylus, Ostrea, Pecten, Cytherea, Arca, Terebratula, Orthis, Clavagella, Echinus, Cidaris, Nucleolites, Brissus, Spatangus; in the Marl the Nautilus zigzag; in the Yellow, Black and Greensand shells of Lenticulites complanatus, teeth and vertebrae of Squalidae and Cetacea ”
