Summary.1 Water from tanks and reservoirs at the Societ.y's Aquarium has bee11 examined over a period of a year with respect to excess base, hydrogen ion concentration salinity, oxygen content, and pal tial pressure of carbon dioxide. 2 Similar estimations have been carried ont on fresh sea‐water sent froin tile Bay of Biscay, Plymouth outside sea‐water, Plymouth dquariuin water, aud tank water from University College Aquarium, London. 3 In all cases the values are found to deviate from the normal to a greater or less extent. 4 Plymouth Aquarium water maintains a nearly constant pH, as it is treated with lime, but is supersaturated with carbon dioxide. 5 The Society's Aquarium shows the greatest variation in hydrogen ion concentration and partial pressure of carbon dioxide, but the animals adapt themselves to this. 6 The rate at which the excess base alters in the Aquarium when a new consignment of water is used was examined. 7 The advantages of liming aquarium water are discussed.
