  Interesante... por aquí enconte algo de información sobre el eclipse de 1878
y *los* planetas intra-mercuriales:

   There was one more flurry after the total solar eclipse at July 29 1878,
where two observers claimed to have seen in the vicinity of the Sun small
illuminated disks which could only be small planets inside Mercury's orbit: J.C
Watson (professor of astronomy at the Univ. of Michigan) believed he'd found
TWO intra-Mercurial planets! Lewis Swift (co-discoverer of Comet Swift-Tuttle,
which returned 1992), also saw a 'star' he believed to be Vulcan -- but at a
different position than either of Watson's two 'intra-Mercurials'. In addition,
neither Watson's nor Swift's Vulcans could be reconciled with Le Verrier's or
Lescarbault's Vulcan.
