In an earlier paper the writer has discussed the paragenesis - kyanite-omphacite as observed in certain ec|ogites. The fate of this association under conditions of retrograde metamorphism has led to a consideration of rocks showing the paragenesis amphibole-kyanite, a point which is briefly taken up in the present communication. Rocks containing this latter assemblage include two groups, the one better known, of sedimentary origin, the other essentially igneous in origin.Here are included members of the para-amphibolites, biotite-hornblende- schists, and hornblende-Garbenschiefer derived from sediments of the character of calcareous and dolomitic shales. The best-known examples come from the Alps—particularly the Triassic and pre- Triassic sediments on the south side of the St. Gotthard massif.

No scene in Faulkner is more compelling than the one that transpires on a “long still hot weary dead September afternoon” in Yoknapatawpha County, Mississippi, toward the end of the first decade of this century. Quentin Compson sits with Miss Rosa Coldfield in a “dim airless room” still called “the office because her father called it that,” and listens to Miss Rosa tell her version of the story of the “demon” Sutpen and his plantation, Sutpen's Hundred. As she talks “in that grim haggard amazed voice”—“vanishing into and then out of the long intervals like a stream, a trickle running from patch to patch of dried sand”—the 22-year-old Mississippi youth discovers he is hearing not Miss Rosa but the voices of “two separate Quentins.” One voice is that of the “Quentin preparing for Harvard in the South, the deep South dead since 1865 and peopled with garrulous baffled ghosts.” The other voice is that of the Quentin “who was still too young to deserve yet to be a ghost, but nevertheless having to be one for all that, since he was born and bred in the deep South the same as she [Miss Rosa] was.” The two Quentins talk “to one another in the long silence of notpeople, in notlanguage: It seems that this demon—his name was Sutpen—(Colonel Sutpen)—Colonel Sutpen. Who came out of nowhere and without warning upon the land with a band of strange niggers and built a plantation”.

The crab whose habits I now describe has not previously been recorded as an inhabitant of British seas. I found two specimens, both male, imbedded in a patch of coarse shell sand on the south side of Drake's Island at low water, spring tides: one on August 11th, 1896, and the other on the following day.

The author remarks that the existence of Annelida during the Palæozoic formations is manifested in two conditions. In the one, we have the shelly envelope which invests the order Tubicola, in the form of Seapolites; and in the other, the tracks of the orders Abranchia and Dorsi-branchiata are found impressed on deposits which were, at one time, in a sufficiently soft state to receive the impressions of the wanderings of these animals.Among the strata which have hitherto afforded annelid tracks, those which, in the county of Clare, represent a portion of the equivalents of the Millstone Grit, contain such tracks, in their most perfect state of preservation in great abundance; and these strata also furnish evidence concerning the circumstances which prevailed during their deposition.

Over the last few years, data studies within Social Sciences watched a growth in the number of researches highlighting the need for more proficuous participation from the Global South in the debates of the field. The lack of Southern voices in the academic scholarship on the one hand, and of recognition of the importance and autonomy of its local data practices, such as those from indigenous data movements, on the other, had been decisive in establishing a Big Data in the South agenda. This paper displays an analytical mapping of 131 articles published from 2014-2016 in Big Data & Society (BD&S), a leading journal acknowledged for its pioneering promotion of Big Data research among social scientists. Its goal is to provide an overview of the way data practices are approached in BD&S papers concerning its geopolitical instance. It argues that there is a tendency to generalise data practices overlooking the specific consequences of Big Data in Southern contexts because of an almost exclusive presence of Euroamerican perspectives in the journal. This paper argues that this happens as a result of an epistemological asymmetry that pervades Social Sciences.


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.


When free magnetism is developed by induction, and is not retained in that state by what has been termed the coercive force of hard steel, it has generally been considered that all the phenomena due to the existence of free magnetism cease on the removal of the inducing cause. The object of the present communication is to show that such is not the fact. From a variety of experiments described by the author, it appears that soft iron continued to exhibit strongly the attraction due to the developement of magnetism long after the means by which the magnetism had been originally excited had ceased to act. In these experiments, bars of soft iron, in the form of a horseshoe, had a single helix of copper wire wound round them, so that on the ends of the wire being brought into contact with the poles of a voltaic battery, the iron became an electromagnet. With one of these horse-shoes, while the connexion between the ends of the helix and the poles of the battery existed, the soft iron, having a keeper applied to its poles, supported 125 pounds it supported 56 pounds after that connexion had been broken, and continued to retain the power of supporting the same weight after an interval of several days, care having been taken not to disturb, during the time, the contact between the horse-shoe and its keeper. On this contact, however, being broken, nearly the whole attractive power appeared to be immediately lost. The author describes several instances of the same kind, particularly one in which the contact between the ends of the horse-shoe of soft iron and its keeper having been undisturbed during fifteen weeks, the attractive power continued undiminished. Although the interposition of a substance, such as mica or paper, between the ends of the horse-shoe and its keeper necessarily diminished the force of attraction, it did not appear to diminish the power of retaining that force. In a case where the electromagnet of soft iron and its keeper were equal semi-circles, the author found, what may appear singular, that the arrangement of the magnetism during the time that the electric current traversed the helix, appeared not to be the same as after the cessation of that current; in the one case similar, and in the other dissimilar, poles being opposed to each other at the opposite extremities of the two semi-circles. Whether the magnetism was originally developed in the soft iron by means of an electric current passing round it, or by passing over its surface the poles of an electromagnet, or those of a common magnet of hard steel, it appeared to possess the same power of retaining a large portion of the magnetism thus developed. The retention of the magnetism does not appear to depend upon the relative positions of the ends of the horse-shoe and the keeper remaining undisturbed, but on their contact remaining unbroken: for one keeper was substituted for another without diminution of this power; care being taken that the second should be in good contact with both ends of the horse-shoe before the complete removal of the first.

Similar to the romanticized images that Manchuria would evoke with Japanese citizens looking for a better life in the 1930s, but on a larger geographical scale and over a longer chronological period, the Nan'yô, or South Seas, conjured up a multiple of idyllic visions within the imaginations of many Japanese. In Japanese perception over the course of the Meiji and Taishô periods, the Nan'yô became a region as diverse and as expansive as the interests and energies of those who directed their attention toward it. To disenfranchised ex-samurai, it was a warm tropical paradise, a territory in which to gain personal achievements and fulfill a sense of adventure. Politicians, journalists, and patriots hoping to plant the Japanese flag for national glory mistakenly viewed the South Seas as the one area untouched by Western imperialists and thus the optimal place for the new nation of Japan to acquire territories. On the other hand, certain entrepreneurs came to view the South Seas as a resource-rich economic treasure house, an area waiting to be exploited through commerce and industry.

Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme north-west part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters.

One of the striking facts about the social and political history of Haiti from independence in 1804 to the present is the deep gulf separating the largely mulatto elite groups from the predominantly black masses. The war of the South in 1799 between Toussaint and Rigaud, and the conflicts between Christophe and Pétion, while not primarily caused by color factors, were reinforced by suspicions and hostilities between black and mulatto, with each group accusing the other of prejudice and discrimination. Politics in the rest of the nineteenth century can generally be seen as a tussle between a mulatto elite centered in the capital and in the cities of the South, on the one hand, and a small black elite often in alliance with army leaders and peasant irregulars, on the other. In the years following 1867 these groups formalized themselves into a largely mulatto Liberal Party, and a preponderantly black National Party.
