rooms, used as lecture-room, laboratories, store-rooms, and exhi- 
bition-rooms. A visitor to the Museum in those early days 
would now find it difficult to recognize the rooms or their con- 
tents in the present arrangement. The ground covered by the 
building as it stands to-day is five times as great. There are no 
less than eighteen exhibition-rooms,* with their corresponding 
galleries, of which eleven are open to the public. Thirty-two 
rooms are used for storage and quarters for special students 
and assistants. ‘There are also a lecture-room, a Curator’s room 
and office, eleven laboratories of biology and geology for College 
and advanced students, four rooms devoted to the Library, and 
in the basement, in addition to boiler space, rooms intended as 
an Aquarium and Vivarium and for receiving freight ; — making 
in all seventy-one rooms, the dimensions usually being thirty 
feet by forty, and twelve galleries. 
Of course, this result has not been attained without a very 
considerable expenditure, and from the nature of the case a cer- 
tain waste could not be prevented. In addition to the ordinary 
income of the Museum about half a million of dollars has been 
expended since 1875 for land, the buildings, the collections, and 
the publications. 
We have probably reached the limit of a university organiza- 
tion for such an institution. While it undoubtedly is capable of 
indefinite expansion in the way of endowments for special pro- 
fessorships and assistants, it is doubtful if it is wise to expect or 
aim at any expansion beyond that which naturally comes from 
the demands of endowed chairs in a university. Original in- 
vestigation has always been best promoted in connection with 
educational institutions, and, in conformity with their demands, 
museums should grow so fast and no faster, unless they are to 
become mere unwieldy and meaningless accumulations. 
The difficulty, if not impossibility, of uniting with other insti- 
tutions, so as to avoid repetitions which are often both useless 
and expensive, is a most discouraging feature in museum admin- 
istration. No matter how the field may be preoccupied, each 
director will pride himself upon his success in having accom- 
plished what probably has already been done by others. No 
doubt, in a country covering so great an area, and with the dense
