NOTICE OF JOHANN WILHELM ZETTERSTEDT

XIV, 1860) that Zettersteclt, at the age of seventy-five, as if in 
forgiveness of the past, placed the dedication: “ Viro amplissimo, 
Doctori H. Loew, Professori et Directori in Meseritz, Posnaniae, 
Plur. Societ. Litterar. Membro, Dipterologo nostri aevi celeber- 
rimo, hunc sui operis tomum dicavit.” In 1868, on the occasion 
of receiving Schiner’s “Novara ” work from the author, Zetterstedt 
sent him his photograph with the inscription: “ J. W. Zetterstedt, 
natus Maji 1785 Lund, — die 25 Maji 1868 grata et arnica mente 
salutat celeberrimum et nostri aevi Dipterologum facile principem 
Dom. Doctorem J. Rud. Schiner.” Schiner was delighted with 
this compliment as testified by him in his letter to me July 30, 
1868. 
An excellent article containing an impartial appreciation, and at 
the same time a criticism of Zetterstedt’s “ Diptera Scandinaviae ” 
was published by Haliday ( Natural History Review , July, 1855, 
p. 43-61). He says (p. 53) : “ The system of the ‘ Diptera Scan¬ 
dinaviae ’ is avowedly an artificial one; but viewed simply as such, 
it does not seem to fulfil its end well enough to compensate for 
the disregard of natural affinities. Zetterstedt, in grateful deference 
to the authority of his illustrious master in entomology [Fallen], 
retained in a great measure the arrangement and the nomenclature 
of Fallen’s older System, although his unbiased judgment might 
have been better satisfied with the more recent Systems of Meigen 
or Mac quart.” 
Zetterstedt, in his Preface (Vol. I, p. viii), has distinctly ex¬ 
plained that he only aimed at an artificial arrangement, a fact 
which has been often overlooked by those who have made use 
of his work. I have especially insisted on this point in an article 
in the Berl. Hnt. Zeit ., 1897, (p. 151, at bottom). Zetterstedt’s 
defects notwithstanding, his life-work is a great one; as Haliday 
says (Joe. cit., p. 52): “His great work, a monument of untiring 
industry, erudition, and acute discrimination, is comprised in 
eleven 8vo volumes [this was written in 1855; the number 
increased to fourteen in 1860. — Osten Sacken] which average 
above 400 pages each; and the publication, commenced at the 
author’s own expense, and afterwards worthily sustained by 
the public purse, has extended over a period of ten years.” [In
