Trouessart, Catalogus Mammalium 
Recensionen. 
R. Lydekker (Annals und Magazine of Natural History): Stupendous 
task. . . All naturalists owe him a debt of gratitude, 
the extent of which is almost impossible to express 
in words ... Dr. T. must possess patience and industry 
far above the average, while he has also the technical 
knowledge of his subject which raises the work to a 
much higher level than the efforts of the mere com¬ 
piler and bibliographer. In the name of our fellow 
students we beg to tender to the learned author our 
most hearty congratulations and thanks. 
Dr. 0. H. Merriam (‘Science’): Of such great practical uti¬ 
lity, that for years to come every student of living or 
fossil mammals must keep a copy at his elbow and 
will owe to its author a debt of gratitude. 
Dr. J. A. Allen (‘The American Naturalist’): Mammalogists owe to 
Dr. T. a large debt of gratitude... A work which will 
prove an enduring monument to the patience, industry 
and scientific acumen of its author... The labor in¬ 
volved in this compilation is thus beyond easy con¬ 
ception, and its value to fellow-workers is inestimable. 
M. R. 0. Thomas (‘Natural Science’) : Got up by Messrs. Fried- 
lander in a superior style... Will have to be in the 
library of every mammalogist and will be of more use 
than the great majority of more port’entious works, 
M. Cossmann (‘Revue critique de Paleozoologie’): Ce catalogue 
comble une reelle lacune . . . Nous n’avons pas a faire 
l’eloge de notre savant collaborateur, dont la compe¬ 
tence est bien connue. 
Revue Scientifique: Extremement complet, et tout a 
fait remarquable par l’abondance et la richesse des 
informations ... II a fallu une patience et un labeur 
vraiment formidables . . . Tous les hommes de science 
doivent etre reconnaissants a M. Trouessart de sa 
hardie et laborieuse initiative. 
Natur: Eine ausserordentlich verdie nsvolle Arbeit, die 
durch Beriicksichtigung der fossilen Arten einen 
doppeltenWert gewinnt. 
Prof. H. Nitsche (‘Litterarisches Centralblatt’): Die miihsame Arbeit 
ist hochst dankenswert undwird alle n nachf olgenden 
Bearbeitern einschlagiger Themata ihre Untersuch- 
ungen wesentlich erleichtern. 
B. Langkavel (‘Zoologisches Centralblatt’): Ein unentbehrliches 
Hand- und Nachschlagebuch.
