down to fact.  This was from no natural lack of volatility, for he was an Acht-und-vierziger (Forty-eighter).  In 1846, as a prosector in the University of Berlin, Virchow entered with Reinhardt upon a series of pathological investigations which at once received wide attention.  In conjunction with Reinhardt, he founded the Archiv fuer pathologische Anatomie und Physiologie und fuer klinische Medicin[6] (a periodical familiarly called “Virchow’s Archiv"), the publication of which was begun in the year 1847.  Reinhardt died in 1852, leaving the editorship in the hands of Virchow alone, and he was still its editor up to the time of his death, on September 5, 1902.

In consequence of his having openly proclaimed himself a Democrat in 1848, Virchow was forced to retire from the University of Berlin in the following year.  He was at once made a professor in the University of Wuerzburg, whence seven years later, in 1856, as the result of the strenuous interposition of various medical organizations, he was recalled to Berlin, where he was made a professor and director of the Pathological Institute.  He was appointed medical privy councillor in 1874, having several years before that entered upon an active political career and been one of the founders of the Progressive party, which he ably represented in the Landtag and the Reichstag.  In 1869 he took part in founding the German and the Berlin Anthropological Societies, of each of which he was several times president.

Virchow investigated the most diverse subjects, as his profound studies of Schliemann’s discoveries, as well as his other archaeological researches, show, and he was a rather prolific writer.  The most important of his early works was Die Cellularpathologie, the first edition of which was published in 1858.  Chance’s English translation appeared in 1860, and Picard’s French version came out in 1861.  It is safe to say that no book of the century exerted a profounder influence on medical thought than Virchow’s exposition of the cellular pathology.  His next notable publication was a collection of thirty lectures on Tumors (Die krankhaften Geschwuelste,[7] Berlin, 1863-67).  That he was not too absorbed in these lectures to bring his great powers to bear upon topics of the day is shown by the fact that before their publication was completed he brought out his work on Trichinae (Darstellung der Lehre von den Trichinen, 1864).  Old age found him with industry and versatility unabated, for it was in 1892 that his Crania ethnica americana appeared, and after that time he wrote a vigorous protest against the new-fangled spelling of the German language which he accused the schoolmasters of trying to foist on the people.  This was published in his Archiv.  It may well be that his arguments have not been unavailing, since it is observable that several German publications that had adopted the new spelling have now dropped it.
