Murders in the Rue Morgue (1932 film) the Rue Morgue" were disappointing, and Lugosi's original Universal contract for "Dracula" was not extended. Today, however, the film is generally well-regarded by critics and is considered a cult classic. In Paris in 1845, a mad scientist, Dr. Mirakle (Bela Lugosi), abducts young women and injects them with ape blood, in order to create a mate for his talking sideshow ape Erik (Charles Gemora, the gorilla performer). Young Pierre Dupin, a young naive medical student and detective (Leon Ames — credited as Leon Waycoff — in the role of Poe's standard detective icon, C. Auguste Dupin), his fiancée Camille L'Espanaye
Dupin cyclide of Dupin cyclides is invariant under the larger group of all Lie sphere transformations; any two Dupin cyclides are Lie-equivalent. They form (in some sense) the simplest class of Lie-invariant surfaces after the spheres, and are therefore particularly significant in Lie sphere geometry. The definition also means that a Dupin cyclide is the envelope of the one-parameter family of spheres tangent to three given mutually tangent spheres. It follows that it is tangent to infinitely many Soddy's hexlet configurations of spheres. A further special property of a cyclide is: An elliptic cyclide can be represented parametrically by the following formulas
