For cofinite Kleinian groups, with finite-dimensional unitary representations, we derive the Selberg trace formula. As an application we define the corresponding Selberg zeta-function and compute its divisor, thus generalizing results of Elstrodt, Grunewald and Mennicke to non-trivial unitary representations. We show that the presence of cuspidal elliptic elements sometimes adds ramification point to the zeta function. In fact, if D is the ring of Eisenstein integers, then the Selberg zeta-function of PSL(2,D) contains ramification points and is the sixth-root of a meromorphic function., 25 pages, submitted to Mathematische Zeitschrift

Two cases of ruptured duodenal ulcer occurring in patients previously treated with metrazol are described. The theory that there may be a causal relationship between the preceding metrazol therapy and the later gastrointestinal pathology is advanced.
