NINTH ANNUAL REPORT. 101 
that a limited number of species do withstand it for considerable 
periods, the renewal of the supply of sea fishes would be neces- 
sary more frequently. 
The completion of the work on filters, now in progress, will 
permit of the new reservoir for pure sea water being brought 
into use, when immediate relief from troubles due to brackish 
water may be expected. The long endurance, under these condi- 
tions, of the species named below is very interesting zoologically :

SHUDS TOE “BISE SDISDASES: 
Like all institutions of the kind, the Aquarium suffers losses 
of specimens from causes other than those attributable to a bad 
water supply. As diseases of several kinds are common, arrange- 
ments have been made recently for the pathological examina- 
tion of all fishes dying in the Aquarium. All specimens lost, 
from any cause whatever, are now sent to a physiological labora- 
tory for examination. The fishes are fully labeled as to name, 
locality, time kept in the Aquarium, and duration of disease. 
These data, together with subsequent notes by the pathologist on 
each specimen, will, it is believed, constitute a record of value to 
aquarists, and lead to more successful management of fishes in 
captivity.
