Mara Has No Atmosphere.

San Jose, Cal., Aug. 30. —Prof. Campbell, of Lick Observatory, has demonstrated with the spectroscope that the planet Mars presents no evidence of having an atmosphere. Prof. Holden says that if any atmospheric pressure exists it is not as great as on our highest mountains and that popular fancies concerning that planet are thus disproved.
