First, all major silicate mineral classes are tested, and the effects of organic materials on the formation of filamentary sublimate residues (FSR), silicates resembling those formed from subliming dirty ice in comets, are investigated. Organic FSR resembles the structure observed to cover most of the nucleus of Halley's comet. Second, the morphology of the outflow of the OH radical in the inner coma of Halley's comet is investigated. When a ratio is made of images of the comet in the OH (1-1) and (00) bands (around 3100 A), the resulting image maps the projection along the line of sight of the sunward velocity of the gas in the coma. Qualitative interpretation of these images shows that, although constant velocity, spherically symmetric outflow is usually observed, gas jets and other asymmetries are not uncommon. Poor quantitative agreement with the theory (Schleicher and A'Hearn 1982) suggests either gas outflows on the order of 4 km sec, or fine structure in the ratio which was not modeled in the theory.
