examined for phosphorescence. On each such occasion the tow-nettings 
previously there were also examined, as also at other intervals during the 
day. In none of the three was any phosphorescence seen till about 
5-40 p.m., when a single organism was seen to spark in the second tow- 
netting (taken 3-45 to 4 p.m.), but nothing in the first or third. 
Examined at 6-45, when it is dusk outside, all three are 
phosphorescing spontaneously, bright sparks showing up, sometimes three 
or four at once in each dish. On stirring there is a bright display lighting 
up each dish. All three left over-night in dark room. 
Thursday, September 24th—lUxamined at 10 a.m., none of the three 
tow-nettings show any phosphorescence in the dark room. Nos. 1 and 3 
were kept in the dark room all day, while No. 2 was kept in the daylight, 
but taken at intervals to the dark room for examination. No 
phosphorescence seen in any of the three at any time during the day; but 
at night (7 p.m.) all three are sparking spontaneously, showing bright 
sparks at intervals. The phosphorescence is increased on stirring, so that 
six to ten phosphorescent spots are visible at once, but the display is not 
so brilliant as on the previous night, probably owing to deaths. 
All three left in dark room till Friday morning; the faint ruby light 
from the dark room window is completely shut off by banking it up with 
cardboard on the outside. 
This same day, being a bright day with good sunlight, three 
additional tow-nettings were taken, at 11 to 11-15 a.m., 12-45 to 1 p.m., 
and 4-45 to 5 p.m., and examined in future along with the other three, 
being kept in dark room also. Examined as follows in dark room :— 
No. 1 observed at 11-30 a.m. net .... No phosphorescence. 
Nos. 1 and 2 observed at 1-15 p.m. ... .... No phosphorescence. 
Nos. 1, 2 and 3 observed at 5-10 p.m. ... No.1, Nil; No. 2, single 
spark on vigorous 
stirring; No. 8, Nil. 
Nos. 1, 2 and 3 observed at 5-35 p.m. ... Nil; single spark ; Nil. 
(Good light outside).
