The total number of persons who have visited the Aquarium 
since it was opened fifteen years ago exceeds thirty millions, or an 
average of over five thousand a day. 
For several years daily records of the temperature and 
salinity of the waters of the Harbor have been kept at the Aquar- 
ium, where it is still used in some of the floor pools. 
The records have a scientific value as showing the low salin- 
ity of the harbor water in comparison with that of the open sea. 
It is usually less than half as salt, and is foul with sewage and 
manufacturing wastes. 
The highest salinity is observed in August; the lowest in 
April.
