S ummary .1 The micro‐biological conditions existing i n the sea and fresh water circulations of t h e Aquaxiinn have been investigated, and t h e efficiency demonstrated of filtration and storage for the removal of micro‐organisms (other than bacteria). By for the largest proportion of the organisms exist in the idgal and fungal growths lining the sides and out, flows of the show‐tanks. 2 The success of the purification methods employed in the Aquarium is also shown by the raduction in the total number of bacteria passing from t h e show‐tanks through the circulation. 3 Bacteriologi‐al investigation reveals the fact that dark storage is responsible for the elimination of 66 per cent. of the ordinary bacteria and 97 percent of the so called “blood‐heat” organisms and bacteria of the human intestinal type.
