The structural and dynamical properties of the Bok globule, B335, are determined from extensive millimetric spectral observations of CO isotopes and various other molecular species. The authors present the density, mass, and temperature distribution and analyze the velocity structure of B335. It contains a condensed core with a mass of 11 - 14 M_sun; coincident with the optically opaque core. Embedded in the core is a low-mass star or protostar as evidenced by high-velocity flows and far-infrared photometry. The core is collapsing at a rate considerably smaller than that of free fall and rotating with a period of 1.7×107yr. The core is surrounded by an envelope that extends well beyond the region of significant visual obscuration. Embedded in the envelope is another bipolar flow aligned with the flow in the core. A nonspherical cloud model incorporating magnetic fields is presented for B335.
