ELECTRIC DISCHARGE WITH THE CHLORIDE OF SILVER BATTERY. 193 
122. — Pressure 0*12 m.m., 158 M, 2400 cells, C. 0*01772 W. Only a nebulous 
discharge, but on introducing 500,000 ohms thick strata were produced, 
as 11, fig. 50; the discharge at the negative ring was trifurcated, the 
central arm passing through the centre of the ring. 
123. — Pressure 0*03 m.m., 39 M. The current of 3600 cells passed. 
Tube 139, 3rd Charge of Hydrogen. 
124. — Pressure 9*331 m.m., 12,276 M, 6960 cells, C. 0*00703 W. One luminosity 
like tube 129, 40, fig. 45. 
125. — Pressure 8*548 m.m., 11,249 6960 cells, C. 0*01234 W. Four luminosities 
arranged in serpent-like form, as shown in 13, fig. 50. 
126. — The pressure had risen without any leakage to 9*502 m.m., 12,526 M, 
6960 cells. One luminosity like that on the left hand in 13, fig. 50. A 
photograph was obtained in 10 seconds but has not been copied. Another 
photograph obtained in 1 minute is shown in fig. 1, Plate 15 ; it will be 
observed that it has a spear-head continuation towards the negative. 
127. — Pressure 6*562 m.m., 9344 IV!, 6960 cells. 10 luminosities like those in 
fig. 5, Plate 15. These ran together to form only two, and separated again 
into ten, the mouth-like ends towards the negative being in continual 
vibration. 
128. — Pressure 4*615 m.m., 6073 M, 5880 cells, C. 0*02693 W. A series of 
luminosities, the first near the negative ring being the flat-hat-shape like 7, 
fig. 50, the remainder like fig. 7, Plate 15. 
129. — Pressure 3*291 m.m., 4330 M, 5880 cells, C. 0*00939 W. Strata curiously 
curved, some with a concavity towards the negative, the remainder having a 
tendency to arrange themselves in a spiral, 19, fig. 50. The current of 
4800 cells passed, but that of 3600 would only do so when the point 
was negative. 
130. — Pressure 1*304 m.m., 1717 M, 2400 rod cells, C. 0*02136 W. Umbrella- 
shaped strata well defined towards the negative, but confused towards the 
positive. 
131. — Pressure 1*244 m.m., 1637 M, 2400 cells, C. 0*01561 W. 
132. — Pressure 0*401 m.m., 528 IV!, 2400 cells. Umbrella-shaped, slightly 
unsteady strata were obtained, between which other fainter ones introduced 
themselves from time to time : this phase is shown at 21, fig. 50, and also in 
the copy of a photograph, obtained in 10 seconds, fig. 5, Plate 16 : these 
strata were blue. The same phase was obtained in experiment 121 at a 
pressure of 0*518 m.m. By the introduction of 700,000 resistance, O. 
0*00088 W, 23 strata were obtained of a pink colour perfectly steady, as 
represented in fig. 6, Plate 16, copied from a photograph obtained in 20
