888 The American Naturalist. [October, 
shows admixture more convincingly than arts, but not more in 
reality to those who are in a position to make comparisons. 
The remark of Prof. O. S. Mason is a reliable statement of the 
question for the present, that " the Easter Island images are the 
most interesting of the archeological enigmas." Mr. Thomson 
is preparing a monograph on Easter Island for a forthcoming 
Smithsonian Report, from the material gathered on the Mohican 
survey and from other sources, which will allow a judgment to 
be passed on these questions, and which will give all that is 
known about the archeology and ethnology of this interesting 
field. 
ARE THE GERMAN SCHWEINE-SEUCHE AND THE 
"SWINE PLAGUE" OF THE GOVERNMENT 
OF THE UNITED STATES IDENTI- 
CAL DISEASES? 
/^NE of the most valuable and interesting contributions to the 
^-"^ literature of the German Schweine-seuche is that of 
Bleisch and Fiedeler.^ 
The investigations of these observers appear to have been 
most carefully made, and every necessary precaution used. They 
extended over fifly-two swine, in an outbreak in which sixty of 
sixty-three died. According to their statement, the same micro- 
organism to which the name •' Loeffler-Schiitz " has been given, 
was found in every case, of which they say : " While the disper- 
sion of the bacteria in the organs and blood of the inoculated 
rabbits and hens is in general about equal, these investigations show 
that in swine they are most numerous in the mucus filling the 
bronchial tubes which lead to the diseased portions of the lungs, 
and less numerous in the caseous parts, while equally scarce or 
wanting in the gray-red hepatized portions as well as in the 
spleen and liver.
