Contents: Preface. Panspermia 2000. Part 1: General Considerations. 1.1. On a possibly fundamental principle in Chemistry as viewed in a cosmogonic context. 1.2. Biological activity in the early solar system in its outer regions. 1.3. An object within a particle of extraterrestrial origin compared with an object of presumed terrestrial origin. 1.4. The viability with respect to temperature of micro-organisms incident on the Earth's atmosphere. 1.5. A laboratory experiment with relevance to the survival of micro-organisms entering a planetary atmosphere. 1.6. Biological Evolution. 1.7. Metallic particles in astronomy. 1.8.

Formaldehyde polymers in interstellar space. 2.2. Formaldehyde polymers in comets. 2.3. Composition of cometary dust: the case against silicates. 2.4. Primitive grain clumps and organic compounds in carbonaceous chondrites. 2.5. Spectroscopic evidence for interstallar grain clumps in meteoritic inclusions. 2.6. Calculations of infrared fluxes from galactic sources for a polysaccharide grain model. Part 3: Cosmic Micro-Organisms: Infrared Characterisation. 3.1. Infrared spectroscopy of micro-organisms near 3,4lambdam in relation to geology and astronomy. 3.2.
