It will be noted that the velocities of the diffuse cosmic matter, 

 or cloud, which are obtained from the displacement of the inter- 

 stellar H and K lines in the same way as the stellar velocities from 

 the hydrogen and helium lines, are given in the sixth column, and 

 that these velocities show an even closer agreement with those that 

 would be produced by a rotation of the galaxy, given in the seventh
