On the 19th of May 1218 he died at the Harzburg after being loosed from the ban by a Cistercian monk, and was buried in the church of St Blasius at Brunswick.
But in 1681 Gerard Blasius had brought out at Amsterdam an Anatome Animalium, containing the results of all the dissections of animals that he could find; and the second part of this book, treating of Volatilia, makes a respectable show of more than one hundred and twenty closely-printed quarto pages, though nearly two-thirds is devoted to a treatise De Ovo et Pullo, containing among other things a reprint of Harvey's researches, and the scientific rank of the whole book may be inferred from bats being still classed with birds.
The last, considered the best, was corrected and re-edited by Albert Molnar at Hanau in 1608.7 Heltai published also (1571) a translation, improved from that by Blasius Veres (1565), of the Tripartitum of VerbOczy, and Chronika (1575) adapted from the Decades of Bonfini.
This scheme was the work of Blasius Merrem, who, in a communication to the Academy of Sciences of Berlin on the t oth December 1812, which was published in its Abhandlungen for the following year (pp. 237-259), set forth a Tentamen systematis naturalis avium, no less modestly entitled than modestly executed.
For want of space it must here suffice simply to name some of the ornithologists who have elaborated, to an extent elsewhere unknown, the science as regards their own country: Altum, Baldamus, Bechstein, Blasius (father and two sons), Bolle, Borggreve, whose Vogel-Fauna von Norddeutschland (8vo, 1869) contains what is practically a bibliographical index to the subject, Brehm (father and sons), Von Droste, Gatke, Gloger, Hintz, Alexander and Eugen von Homeyer, Ji ckel, Koch, KOnig-Warthausen, Kriiper, Kutter, Landbeck, Landois, Leisler, Von Maltzan, Bernard Meyer, Von der Miihle, Neumann, Tobias, Johann Wolf and Zander.
