136 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
two such stations, but these were the foremost in Europe, namely, 
the Marine Biological Laboratory at Plymouth, England, and the 
Zoological Station at Naples, Italy. 
Marine Biological Laboratory, Plymouth.—The laboratory occupies 
a bluff 110 feet above Plymouth Harbor, and affords a strikingly fine 
view of this historic roadstead, with Eddystone light-house in the dis- 
tanee. The building, which, with its equipment, cost about £12,000, 
is constructed of gray sandstone, and consists of a two-story central 
part with two square three-story wings or towers. The lower floor 
contains an aquarium, the second floor is occupied by the main labora- 
tory and rooms opening therein, and the upper story is devoted to a 
library, general rooms, ete. Water for the laboratory and aquarium 
is pumped from the harbor into large cement-lined pools under the 
building, holding about 100,000 gallons, thence to tanks with capacity 
for 5,000 gallons at the top of the building, whence it is led by gravity. 
The vessels and boats belonging to the station are a 7-ton steamer, a 
40-ton barge, and two small sailboats. 
The laboratory is under the control of the Marine Biological Asso- 
ciation of the United Kingdom, of which Prof. E. Ray Lankester is 
president, and is supported by annual subsidies from the government 
and the Fishmongers’ Company, of London, by annual subscriptions, 
by fees of investigators, by paid admissions to the aquarium, and by the 
sale of specimens and publications. The resources of the institution 
in 1899 were about £2,000. The director receives an annual salary 
of £200. 
The accommodations are rather limited, there being only ten tables 
for investigators. Those entitled to the privileges of the laboratory 
are the nominees of the founders of the institution and of the persons 
who have endowed tables. There are no restrictions as to the sub- 
jects which may be studied. The laboratory fees of investigators are 
30s. a week, which amount covers all materials and supplies except 
the more costly reagents. No sleeping or eating accommodations 
are afforded by the laboratory except to the director, who has an office 
and private rooms in the building. The laboratory is open throughout 
the year, but is occupied mostly in summer and during the Easter 
and Christmas holidays. 
The aquarium is small, but attractive, and devoted to the marine 
species of the vicinity. The general public is admitted from 10 to 6 
o'clock daily on payment of an entrance fee of 6d., which is reduced 
to 2d. on Wednesdays. The disease known as ‘‘ pop-eye,” which is 
observed in aquarium fish in America, is quite prevalent here. 
The Journal of the Marine Biological Association, a quarterly, is 
the official organ of the laboratory. 
The Naples Zoological Station.—This institution, the largest and 
most noted of its kind, is situated in a spacious park near the shore 
of the beautiful Bay of Naples. Investigators here have the advan- 
tage of climate that is perpetually mild, physical surroundings of great
