90, 95, 100 and 109 is estimated to be 2 m .78,4 m .72, 2 m .69, 3 m .33, 2 m .61, 2 m .86, 4 m .67, 6 m .21, 3 m .14, 3 m .92, 2 m .69, 3 m .04, 5 m .95, 5 m .95, 3 m .20 and 5 m .66, respectively. For most of these stars the absorption lies between 0 m .5 and 2 m .5. This large absorption may be caused by circumstellar absorption. The dust in the associations Gem B 0.41 and Gem B 0.72 is distributed nonuniformly. There is no dust in the space between the associations. Essentially there is no dust inside those groups (associations) which lie at distances greater than 1 kpc.
