arvensis, and P. coronata upon Rhamnus frangula* In the 
following year, 1866, Oersted showed that Gymnosporangium 
sabine and juniperinum were similarly connected with 
Restelia cancellata and cornuta; and in 1867, that G. cla- 
varieforme was connected with R&. Jacerata. In 1869, 
Fuckel indicated the connection of Uvomyces juncc with 
ic. zonale. In 1873, Magnus worked out the life-history 
of P. caricis in its relationship to 4c. urtice ; and Schréter, 
in the same year, the hetercecism of 4c. ranunculd bulbosi 
and Uromyces dactylidis. Since this time these facts have 
been repeatedly verified by numerous workers, and our 
knowledge of the subject has continuously increased, as 
the subjoined tabular statement will show.
