96 Mr. C. Tomlinson on some Phenomena 



Experiment 11. — Absolute alcohol. 



o 



Bath 184 Alcohol 154. Minute bubbles as before. 



195 1/0. Bubbles larger ; an interval without any 



bubbles. 

 197 174. One large bubble. 



179. A large bubble rose at each rise of 1° 

 up to 

 200 184. 



193. Burst of vapour. 

 190. Burst. 

 200 182. 



187. Burst. 



176. The boiling now became regular. 



Experiment 12. — Ether. Boiling-point 95° F. 



Bath 144 Ether 120. Evaporation regular, without bubbles, 

 but so rapid that the bulb of thermo- 

 meter soon became uncovered. 

 Experiment 13. 



Bath 130 Ether 106. Burst of vapour, and a fall of temperature 

 several times. 



Experiment 14. — Ether in retort*. 



Bath 210 Ether ?. Boiling rapidly over. 



178 120. Bursts of vapour from the bottom of the 



thermometer- bulb. 



170 113. 



166 111. Distillation proceeding rapidly. Glo- 



bules in the spheroidal state moving 

 rapidly over the surface. 



160 112. Bursts of vapour. 



Experiment 15. — Bisulphide of carbon in retort. Boiling- 

 point 118°-4 F. 



Water-bath 186 Bisulphide 134. A point on the thermometer-bulb 



active, and liquid rapidly dis- 

 tilling. 

 180 130. 



170 126. Point less active. Surface of liquid 



falling rapidly. 

 166 125. Nuclear point above the surface; 



liquid distilling. 

 160 123. No appearance of boiling. 



155 121. Distilling. 



148 120. Bulb uncovered. 



Experiment 16. — In retort. 



Bath 196 Bisulphide 120. Nuclear speck very active. 

 187 125. Distilling. 



180 123. Speck active. 



172 119. 



165 118. Bulb uncovered. 



* In this series the retort experiments were conducted by me.
