Outside this, though not in hostility to it, Hanover, Brunswick, Oldenburg and Schaumburg-Lippe formed a separate customs-union, (Steuerverein) by treaties signed on the 1st of May 1834 and the 7th of May 1836, and to this certain Prussian and Hessian enclaves were attached.
This method of solution fails when the discriminant R vanishes, for then the Hessian has equal roots, as also the cubic f.
This can be verified by equating to zero the five coefficients of the Hessian (ab) 2 axb2.
The church also contains the tombs of numerous Hessian landgraves and knights of the Teutonic Order.
There are also the Bose Museum, containing collections of pictures and antiquities of Hessian origin, museums of natural history and ethnography, an industrial exhibition hall, and an industrial art school.
On the Hessian fly, Cecidomyia destructor, Say, the May brood of which produces swellings immediately above the joints of barley attacked by it, see Asa Fitch, The Hessian Fly (Albany, 1847), reprinted from Trans.
Many reforms in ecclesiastical, educational, financial and administrative matters were introduced, and in general the grand-duchy may be said to have passed largely under the influence of Prussia, which, by an arrangement made in 1896, controls the Hessian railway system.
Prussia, on the other hand, announced its determination to carry out the principles of the Union and to maintain the Hessian constitution.
But if the given curve has a node, then not only the Hessian passes through the node, but it has there a node the two branches at which touch respectively the two branches of the curve; and the node thus counts as six intersections; so if the curve has a cusp, then the Hessian not only passes through the cusp, but it has there a cusp through which it again passes, that is, there is a cuspidal branch touching the cuspidal branch of the curve, and besides a simple branch passing through the cusp, and hence the cusp counts as eight intersections.
In the war between Austria and Prussia in 1866, HesseDarmstadt was upon the side of the Austrians; Prince Louis accompanied his troops to the front, and was duly appointed by the grand-duke to the command of the Hessian division.
