Scientific paper

It is noted that, due to the large amounts of hydrogen that would be generated in interplanetary space by the numerous small comets proposed by Frank et al. (1986), inhibition of water vapor by a factor of 3 x 10 to the -9th by very thick dust mantles would be necessary to prevent excitation of a detectable interplanetary Lyman-alpha glow. A forbiddingly large influx of dust would result from these cometesimals, with a carbon influx 350 times larger than the rate of burial of fresh carbon in sediments. Other optical problems associated with these cometesimals are considered.
