The late Sir Benjamin Baker, F.R.S., suggested that the stresses might be measured by experiments with elastic models, and among others, experiments were carried out by Messrs Wilson and Gore a with indiarubber models of plane sections of dams (including the foundations) who applied forces to represent the gravity and water pressures in such a manner that the virtual density of the rubber was increased many times without interfering with the proper ratio between gravity and water pressure, and by this means the strains produced were of sufficient magnitude to be easily measured.
But the empire was vast and weak, and its capital lay far away; in practice, no doubt, the lagoon population enjoyed virtual independence, though later the Byzantine claim to suzerainty became one of the leading factors in the formation of the state.

The virtual stoppage of all supplies of raw materials from abroad necessitated the strictest economy in the use of those available at home, and this led to an elaborate system of Government control.
The equation of virtual work is then formed by taking moments about C, D, E, F of the extraneous forces FIC 2 which act at C, D, E, F, respectively.
On the night of the 9th, however, Colonel Stewart retreated toward Charleston, abandoning 1000 stand of arms. The battle has been classed as a tactical victory for the British and a strategical victory for the Americans, terminating a campaign which left General Greene in virtual possession of the Carolinas, the British thereafter confining themselves to Charleston.
A good deal of morphine is exported to Japan from Europe, and generally passes into China by way of Manchuria, where Japanese products have a virtual monopoly.
For the virtual work of two equal anc opposite forces will cancel in any displacement which is commor to the two surfaces; whilst, if one surface be fixed, the displace ment of that point of the rolling surface which was in contact with the other is of the second order.
He adjusted the difficulties over the regalia, and obtained from the French bishops the virtual repudiation of the Declaration of Gallican Liberties.
