28 TRANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 
Re-examined at 7 p.m., four of the dishes show spontaneous 
phosphorescence, the rate of sparking being extremely slow. The 
remaining dish (the third of the Thursday tow-nettings) has undergone 
putrefaction, and shows no phosphorescence, even on stirring. It is 
taken from the dark room, and all the organisms in it are seen to be dead. 
Stirring elicits two to four phosphorescent organisms at the same 
time in the remaining four dishes. 
Monday, September 28th.—lixamined the four dishes at 2-30 p.m.; 
no phosphorescence obtainable from any of them. Txamined again at, 
7-30 p.m. ‘Two spontaneous sparks seen in the Wednesday dishes in an 
interval of about five minutes; no spontaneous phosphorescence seen in | 
the Thursday dishes. On stirring, about six phosphorescent organisms | 
seen in one of the Wednesday dishes, and three or four in the other; one 
seen in the first of the Thursday dishes, and three or four in the second. 
Tuesday, September 29th..-Examined at 3-30 p.m.; no phos- 
phorescence visible or obtainable. “ixamined again at 9 p.m., there is_ 
spontaneous phosphorescence in both of the Wednesday dishes, and in one 
there is an organism which remains steadily phosphorescent with a dull 
glow all the time. On stirring, about six phosphorescent organisms are 
visible in each of the Wednesday dishes, and the sparking is brilliant. 
In the Thursday dishes, on stirring, there is less display, only two or three 
organisms showing up at once in either. The few organisms are, 
however, quite active, and a single organism in each case Lghts up so as_ 
to illuminate the contents and sides of the whole dish. | 
Wednesday, September 30th—Examined at 11 a.m.; no phos-— 
phorescence, spontaneous or otherwise. Hxamined again at 7-30 p.m., no 
spontaneous phosphorescence during a period of about 5 minutes, but on 
stirring there is a good display in all four dishes. This is the eighth 
night of appearance of phosphorescence in the Wednesday lots, and 
seventh night for the Thursday organisms. 
Thursday, October 1st—Examined the four dishes at 11 a.m.; no 
phosphorescence, spontaneous or on stirring. Jixamined again at 7 p.m., 
there is spontaneous phosphorescence at a slow rate in three (two 
Wednesday and one Thursday), and in all four on stirring.
