Professor Frost has furnished the facts which seem to prove that the last explanation, given in A. N. 4065, of the nebulous appearance surrounding Nova Aquilae, No. 2, is the correct one. This appearance is probably due to chromatic aberration. I) Plates taken with the Yerkes 24-inch reflector

Beobachtungen von

on Sept. 2 1 , Sept. 2 7 , and Oct. 23, 1905, show no nebulosity, 2) Wolf has found a similar effect with other stars having pe- culiar spectra. 3) If due to nebulosity, its intrinsic brightness must be at least 1800 times as bright in proportion to the light, of the star, as that around Nova Persei, No. 2.
