A. J. Southward

In previous papers (Southward, 1950, 1951 Southward & Crisp, 1952, 1954 a, b: see also Kitching, 1950 Moore & Kitching, 1939) it has been shown that the geographical distribution of several common intertidal animals in Britain is related to the temperatures prevailing in the different regions. Species of generally southern distribution in Europe are commonest on, or restricted to, the south and west coasts of Britain, where temperatures are higher, while those species of essentially northern character are commoner in the north and east where the temperatures are lower. Where species of northern and southern distribution occur side by side in the same habitat, and are in competition, it seems important to know the range of temperatures over which processes such as feeding and respiration can be carried out, as well as the often narrower range of temperatures within which breeding can take place (cf. Orton, 1920). For example, the two common intertidal barnacles of the European coasts, Chthamalus stellatus (Poli) and Balanus balanoides (L.), occur side by side only in Britain and Northern France, where they reach the northern and southern limits respectively of their distributions. From the distributions it can be inferred that the vital activities of the two species are keyed to different temperature ranges. This implies that for each species there is an optimum range of temperature, above or below which the species becomes less efficient at feeding, respiring or reproducing. Where the two species occur side by side, there may be periods of the year when one of them is living outside its optimum range, and is at a disadvantage compared with the other species.

The Irish land act of 1881, it is generally agreed, was a victory for the Land League and Parnell, and nationalist policy with regard to the act and the attitude of southern tenants towards it have been many times subjected to detailed examination by historians of this period. In these analyses of the events of 1880–81, however, little reference is normally made to the part played by the different parties and interests in the north of the country. It is often assumed, for example, that the Ulster tenants held aloof from the campaign for reform, lending no more than occasional vocal support to the agitational efforts of tenants in the south and west. Indeed, they were later excoriated by William O'Brien, Michael Davitt and others not only for giving no support to the land movement but also for sabotaging Parnell's policy of testing the 1881 act by precipitately rushing into the land courts to take advantage of the new legislation: ‘that hard-fisted body of men, having done nothing themselves to win the act, thought of nothing but turning it to their own immediate use, and repudiating any solidarity with the southern and western rebels to whom they really owed it’. If, however, northern tenants were harshly judged by nationalist politicians in the years after 1881, the part played by the northern political parties in the history of the land bill has been either ignored or misunderstood by historians since that time. The Ulster liberals, for example, are rarely mentioned, the implication being that they made no contribution to the act even though it implemented almost exactly the programme on which they had been campaigning for much of the previous decade. The northern conservatives, on the other hand, are commonly seen as leading opponents of the bill, more intransigent than their party colleagues in the south, ‘quick to denounce any weakening of the opposition’ to reform, and ‘determined to keep the tory party up to the mark in defending the landlord interest’


The chief circumstance that induced Capt. Flinders to think his observations Upon the marine barometer were worthy of attention, was the coincidence that took place between the rising and falling of the mercury, and the setting in of winds that blew from the sea and from off the land, to which there seemed to be at least as much reference as to the strength of the wind or the state of the atmosphere. Our author’s examination of the coasts of New Holland and the other parts of the Terra Australis, began at Cape Leuwen, and con­tinued eastward along the south coast. His observations, which, on account of their length, we must pass over, show, that a change of wind from the northern half of the compass to any point in the southern half, caused the mercury to rise; and that a contrary change caused it to fall. Also, that the mercury stood considerably higher When the wind came from the south side of east and west, than when, in similar weather, it came from the north side.

Beginning with the death of David and the rise of Solomon, 1 Kings charts the history of Israel through the divided monarchy, when Ahab reigned in the north and Jehoshaphat reigned in the south. This new translation, with introduction and commentary by biblical scholar Mordechai Cogan, is part of the Anchor Bible Commentary series, viewed by many as the definitive commentaries for use in both Christian and Jewish scholarship and worship. Cogan's translation brings new immediacy to well-known passages, such as Solomon's famously wise judgment when asked by two prostitutes to decide their dispute regarding motherhood of a child: "Cut the live son in two! And give half to one and half to the other." With a bibliography that runs to almost a thousand articles and books, Cogan's commentary demonstrates his mastery of the political history described by 1 Kings, as well as the themes of moral and religious failure that eventually led to Israel's defeat and exile.

The Barguzin River flows out of the Barguzin Mountains, through the town of Barguzin and then the coastal community of Ust-Barguzin before it finally loses itself in a broad cove of Baikal known as Barguzin Bay. The only way across the river for miles upstream from the lake is a ramshackle little wooden ferry with a tiny, corrugated steel shed with a wood stove in it and room on its deck for about half a dozen cars. The ferry slips noiselessly away from the end of the road on the south bank, and looking west toward the lake, two ghostly, rusting timber loading cranes loom on the horizon while the river spills over into a grassy marsh on its north bank. Turning back to the east, there’s a small motorboat laboring to get upstream—laboring because it’s attached to a tow rope, which is attached to the ferry. The ferry, it turns out, is just a hapless little barge, at the mercy of the river without the guidance of the motorboat pilot on the other end of the towline. Our crossing takes less than five minutes, and connected to it by nothing but that single strand, the pilot directs the barge into place perfectly on the far side. But the deckhand fails to secure it, the ferry swings wide in the current, spins ninety degrees, and slams butt-end into the dock. The pilot scowls as he turns the motorboat around and uses its blunt bow, covered in a tractor tire, to push the barge back into place, where the deckhand finally lashes it to the dock. The Barguzin is Baikal’s third largest tributary, after the Selenga to the south of here and the Upper Angara to the north. It carries about six percent of the water flowing into the lake, along with migratory fish like omul and sturgeon, born in the shallow gravel beds upriver before wandering downstream to spend most of their lives in the lake. And even though it flows through only two towns between its headwaters and the lake, the Barguzin carries a significant pollution load into Baikal, as well, especially organic chemicals from timber operations.

The process of scientific discovery is something like a walk near Freswick Castle. I assume you’ve never been there. (Neither have I, but a friend has.) Freswick Castle stands at the end of Scotland’s northeast end, at the mouth of the Burn of Freswick in the district of Caithness. As of this writing, it is unlisted in Google Maps, and I had to manually scan the coast to find it. Outside the castle is a simple, unlabeled structure that doubles as a biochemical parable. The castle itself is narrow and three stories tall, with orange shingles and gray stone, set on an arc of narrow beach between hills to the north and cliffs to the south. The building is approximately the cruciform shape of a shrunken cathedral, with the rightward wing moved to the top of the structure so it resembles a lowercase f. If you wander the grounds near Freswick Castle, you will discover a stone wall in the wind-blown waves of yellow- green grass, worn but still standing firm like Hadrian’s Wall. From above, it is a period preceding the castle’s f. Let’s approach this as a scientist, with measurement. From the castle side, this structure resembles the circular stump of a roofless tower, eight feet tall and twice that wide. The stones are ancient sand, compacted and weathered, stained different shades of red from iron deposited millions of years ago, but the mortar is new. But inspection is not enough—we should go in. Walk around to the other side, and an opening appears, as shown in Figure 2.1. The structure is not a closed circle, but it is a spiral wall open to the sea, and to you. Inside, a small stone bench invites you to sit. A window slit next to the bench is an eye to the outside. Surrounded by a jigsaw of rocks, you can hear the echo of waves all around and watch the blue-gray sky above. If the spiral’s opening is a mouth, then you are Jonah in the whale. You are both inside and outside at once.

Again, the genera Citheronia and Eacles are a South American element in our fauna, while the typical Attacinæ, such as Actias, probably belong to the Old World element in our fauna, together with all our Platypteryginœ. Among the Hawk Moths the genera Philampelus and Phlegethontius are of probable South American extraction, though represented now by certain strictly North American species. Mr. Robert Bunker, writing from Rochester, N. Y., records the fact that Philampelus Pandorus, going into chrysaiis Augnst 1, came out Sept. 10 as a moth, showing that in a warmer climate the species would become doublebrooded. And this is undoubtedly the case with many species the farther we go South, where insect activities are not interrupted so long and so strictly by the cold of winter. Since the continuance of the pupal condition is influenced by cold, a diminishing seasonal temperature for ages may have originally affected, if not induced, the transformations of insects as a whole. Butterflies and Moths which are single brooded in the North become double brooded in the South.

The plains of Pyrgi, Kalamoti, and Dotia, in the south-east corner of Chios, form a single geographic unit, bounded in the east by the hills which run inland from the promontory of Agridia, in the west by the low range of Kampia, Aradhopetra, and Kakopetria, and in the north by the more formidable barrier of the central mountains of the island. In them there are traces of several ancient sites, at Pindakas, Dotia, and elsewhere, but these appear to have been little more than isolated farmhouses or small sanctuaries and it is almost certain that most of the inscriptions from the area came originally from the major sites at Emporio and Phanai. From these they have been transported, some as far as Chios town, most to other local sites, to country churches or to the medieval towns of Pyrgi and Kalamoti. In many cases it is now impossible to trace their origin (even those which have reached the comparative safety of the Museum are often without record of their provenance), and it would therefore be pointless to try to isolate the inscriptions of any one ancient centre. For this reason I have collected here, in addition to the few inscriptions discovered in the British School excavations at Emporio, all the other material known to have been found in the area. For convenience I reproduce all but the most accessible texts in full. Generally it has been possible to check earlier readings on the stone (in which case the text is my own without any note of alterations unless they are significant); those which I have not seen are marked with an asterisk.


Significance His comments are optimistic. The other two rival administrations that are based in Libya have resisted efforts to form a unified government, while armed groups (some associated with the administrations, others independent) compete for local dominance. As a result, intermittent escalations in fighting and sporadic attacks by fringe militias continue to occur in parts of the country. Concern has grown about the impact on civilians. Impacts Bombings and outbreaks of intense fighting will remain a risk in key contested locations in the north. Clashes between militias will recur sporadically in the south. The number of migrants working in Libya and seeking to travel to Europe may increase again.

The village of Kalývia Sokhás lies against the base of one of the massive foothills in which Taygetus falls to the plain three or four miles to the south of Sparta (Plate 26, 1). It is bounded by two rivers which flow down in deep clefts from the mountain shelf. The hillside above rises steeply to a summit which is girt with cliffs on all but the west side and cannot be much less than four thousand feet above sea level; this von Prott believed to be the peak of Taleton. Its summit is crowned by the ruins of a mediaeval castle which was undoubtedly built as a stronghold to overlook the Spartan plain; the only dateable object found there, a sherd of elaborate incised ware, indicates occupation at the time when the Byzantines were in possession of Mystra. The location of the other sites mentioned by Pausanias in this region remains obscure, but fortunately that of the Spartan Eleusinion has not been in doubt since von Prott discovered a cache of inscriptions at the ruined church of H. Sophia in the village of Kalývia Sokhás. In 1910 Dawkins dug trenches at the foot of the slope immediately above the village and recovered a fragment of a stele relating to the cult of the goddesses and pieces of inscribed tiles from the sanctuary. The abundance of water in the southern ravine led von Prott to conclude that the old town of Bryseai with its cult of Dionysus also lay at Kalývia Sokhás; but no traces of urban settlement have come to light at the village, and the name rather suggests copious springs such as issue from the mountain foot at Kefalári a mile to the north where ancient blocks are to be seen in the fields.

Tegarama was one of the eastern lands of the Hittite Kingdom. In the geographic sense it is part of the Armenian Highland that is why its history is of special interest to us. Taking into account the fact that the Armenian people had considerable ethnic ties with the Upper Euphrates region, specialists have traditionally tended to identify “Home of Torgom” in the Trans Euphrates region together with the city Tegarama (Assyrian Til-Garimmu) mentioned from the 2nd millennium BC. “Home of Torgom” literally repeats Bet-Togarma mentioned in the Bible. The study of the history of the country of Tegarama is also important because in Armenian historiography, starting from Movses Khorenatsi, Armenian ancestor Hayk is called “Son of Torgom”, and the Armenian people - “People of Torgom”. Most of the researchers located Tegarama in the place of the present settlement Gyurun. By comparing the “Cappadocian”, Hittite and Assyrian sources, Tegarama can be located in the Upper Euphrates valley, on the right bank of the river, to the north of Kargamis, to the west of Isuwa, to the south of Upper Land and to the east of Kanes. The territory of Tegarama was not far from Nesa - one of the initial centers of the Hittites; and it was also one of the initial places of inhabitance of the Hittites. Tegarama also occupied a strategically important position. On the one hand it bordered on the country of Mitanni, on the other hand - on Isuwa. Thus, the country of Tegarama occupied a significant geographic position: on the one hand roads led from here to other western districts of the Armenian Highland, to Tsopk, and on the other hand - to Northern Syria and Northern Mesopotamia. It was also one of the spiritual centers of Hatti.
