ARTHUR ERWIN BROWN. 
On October 19, 1910, there passed away, in 
the Philadelphia Zoological Gardens, Arthur 
Erwin Brown, Se. D., zoologist, and pioneer of 
zoological-garden building in America. The first 
great vivarium to be developed in America was 
the Gardens of the Philadelphia Zoological So- 
ciety, in Fairmount Park. From the birth of 
that institution in 1876 until 1897, Dr. Brown 
was its executive head, with the title of Superin- 
tendent, and as such he blazed the trail for every 
American zoological-garden builder who has

wrought since that time. His connection with 
the Gardens continued until his death. 
Quite independently of Dr. Brown’s admir- 
able scientific and administrative work in con- 
nection with the Philadelphia Academy of 
Sciences and the Wistar Institute, his work in his 
original field entitles him to lasting distinction. 
During the past twenty-five years scores of 
Americans who have been called upon to develop 
“zoos, or zoological gardens and parks of 
larger dimensions, have gone to the Philadelphia 
Gardens, and sought Dr. Brown’s genial, patient 
and helpful counsel; and it is safe to say that no 
man ever sought his advice or help in vain. He 
was recognized as a qualified expert on zoolog- 
ical garden matters, and one of the first impor- 
tant acts of the New York Zoological Society 
was to secure from him an inspection and report 
upon the relative merits of Van Cortlandt, Pel- 
ham Bay and Crotona Parks as possible sites 
for New York’s proposed vivarium. Had he in- 
spected South Bronx Park, it is reasonably cer- 
tain that he would have recommended its selec- 
tion. 
All Americans who are interested in zoological 
parks and gardens have benefitted by the life 
and work of Dr. Brown, and suffer a distinct 
loss by his death. He was a pioneer in what 
has become an important field of scientific en- 
deayor, and as such he is entitled to a perma- 
nent memorial in enduring bronze or marble. 
We have already suggested to Philadelphians 
that a suitable memorial be erected, and have 
offered a subscription toward its cost.

OSBORN’S “AGE OF MAMMALS.” 
About once every ten years there appears from 
the press a work on animal life that looms up 
like an obelisk rising from a plain. Professor 
Henry Fairfield Osborn’s “Age of Mammals” is 
a monument of scientific research, far-reaching 
knowledge and logical conclusions on a subject 
as wide as the world, and millions of years old. 
It is the privilege of but few men to occupy a 
position high enough and broad enough to afford 
a comprehensive view of the mammalian fauna 
of the world, past and present. Thanks to years 
of careful preparation, successful exploration 
and diligent research, the author of the volume 
now before us was peculiarly fitted for the task 
which the finished work represents. “The Age 
of Mammals” is sufficient in itself to justify the 
existence of the Department of Vertebrate 
Paleontology in the American Museum, the rich- 
est of its kind, anywhere, so far as we are aware.
