Issue 4 of Kunstformen der Natur, consisting of 10 lithographs by German biologist Ernst Haeckel and lithographer Adolf Giltsch. Ten of these loose-leaf issues were published between 1899 and 1904. All sets were republished as a single book in 1904
The prints show various organisms, many of which were first discovered and described by Haeckel himself. His depictions of beauty in nature were influential to many artists.
