233 “in part regretting a lost opportunity to pursue such a relation himself”: Smith, (1982), p. 184.
233 “the speed of spiral nebulae is dependent to some extent upon apparent brightness, indicating the relation of speed to distance”: Shapley (1929), p. 565.

235 “The intense publicity that swirled around Mount Wilson's nebular department”: Sandage (2004), p. 284.
235 Even though less than 5 percent of Mount Wilson's major publications in this era involved cosmology: Allan Sandage tallied up the papers and, after discounting the inconsequential ones, found that only 33 out of 760 papers in the Mount Wilson Contribution series, which ran from 1906 to 1949, concerned either galaxies or the universe. Sandage (2004), p. 481.
