**y**s would be a veritable civil war.Among the Yugosla

**y**s the students had always dabbled unduly in politics, and this tend-.The entry of Italy into the war was a serious set-back to the Yugoslav cause, for under the Treaty of London (April 27 1915) she was to obtain, in the event of an Entente victory, wide districts in Gorizia, Carniola, Istria and Dalmatia, peopled by not less than 700,000 Yugosla

**y**s.By this time it was sufficiently obvious that the Yugosla

**y**s were tacitly if not explicitly agreed upon a triple parallel policy, framed for all contingencies.The growing self-confidence of the Austrian Sla

**y**s was shown by the bluntness of their refusal to cooperate with the new Premier, Doctor von Seidler, whose offer of portfolios to their leaders drew from Count Tisza a strong protest in the Hungarian Parliament.The Czechs and Yugosla

**y**s, finding the door thus shut in the face of their national aspirations, even in the modified Habsburg form, naturally stiffened in their opposition.The Yugosla

**y**s were represented by Trumbic and his Committee and by 12 deputies of the Serbian Skupstina, the Czechoslovaks by Benes and Stefanik, the Poles by Zamorski, Skirmunt and Seyda, the Rumanians by Draghicescu, Lupu and Mironescu.The effect of the congress and of this propaganda was to hasten the disintegration in the Austro-Hungarian army, and the High Command (in a communiqué of July 27) admitted that wholesale defections of the Czechoslovaks and the Yugosla

**y**s had.That this recognition had not already been accorded before the collapse of the Central Powers began was due to disunion among the Yugosla

**y**s themselves.Trumbic on his part could not enter a purely Serbian Cabinet without prejudicing that freedom of choice of his compatriots in the Dual Monarchy, upon which the moral case of the Yugosla

**y**s depended.Meanwhile the whole Nationalist press of Italy, actively, encouraged by Sonnino and his entourage, opened a fierce campaign against the Yugosla

**y**s and their western supporters, which rapidly developed into agitation against the Allies.On March 3, however, Italy, who had steadily refused to recognize the accomplished fact of Yugoslav unity and insisted on the Conference only admitting the Yugosla

**y**s as a " Serbian " delegation, declined American arbitration and threatened to withdraw altogether from Paris unless their territorial demands were conceded.This in turn strengthened the hands of the extreme section among the Yugosla

**y**s, who now advanced the full ethnographic claim, involving Trieste and Gorizia as well as Dalmatia and Istria, and at the same time increased their demands against Bulgaria, Austria and Albania.Tardieu suggested a compromise by which the port and district of Fiume with most of eastern Istria and a total population of over 200,000 (mainly Yugosla

**y**s) would form a small buffer state between Italy and Yugoslavia, under the guarantee of the League of Nations.The sole justification for such a claim lay in the terms of the Treaty of London, which the Yugosla

**y**s could not adopt as a basis without stultifying their whole position against Italy.Vivipara, ovipara, a

**y**is the depth of metal, the horizontal sections being equal so long as**y**is less than the radius of the outside FIG.Ignoring temperature effect, and taking the density as a function of the pressure, surfaces of equal pressure are also of equal density, and the fluid is stratified by surfaces orthogonal to the lines of force; n ap, dy, P d z, or X,

**Y**, Z (4) are the partial differential coefficients of some function P, =fdplp, of x,**y**, z; so that X,**Y**, Z must be the partial differential coefficients of a potential -V, such that the force in any direction is the downward gradient of V; and then dP dV (5) ax + Tr=0, or P+V =constant, in which P may be called the hydrostatic head and V the head of potential.Thus if the plane is normal to Or, the resultant thrust R =f fpdxdy, (r) and the co-ordinates x,
