Fasciculus:Leuckart Rudolph 1822-1898.jpg

Situs librariae huius operis theoretice incerta est quia, in regione originis, librae 70 annos post mortem auctoris durant, et tempus mortis auctoris (vel identitatis auctoris) ignoratur. Attamen tempus creationis operis ante 120 annos superatum fuit, et ideo rationabilis suppositio est librariae exspirasse (vide hic de communitate disceptationis). Obsecro, hoc noli utere si tempus mortis auctoris notum est.

You must also include a United States public domain tag to indicate why this work is in the public domain in the United States. Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
