This last feature, while being a sad reminder in one respect, is 

 of value to science, since it shows conclusively the abundance of 

 the fluid included, and also, what is of more importance, that this 

 cementing ice was formed either directly from the fluids in the crys- 

 tals or by influences which they exerted. I do not believe this 

 cementing ice was wholly formed by the freezing of the water 

 contained in the cavities, but was gathered there by the attract- 

 ive influence of the liquid carbon dioxide upon being so sud- 

 denly set free; that this liquid carbon dioxide did, by its 

 natural affinity for moisture, create around it an atmosphere so 

 cold that even the little dampness then existing in the air was 

 congealed upon the crystal fragments. 



As the room was a dark one I had all these masses and larger 

 fragments carried out and placed in the sunlight, for no other 

 reason than to examine them more carefully. I did not antici- 

 pate from this any further developments of scientific interest. 

 Again, believe my astonishment, as soon as the rays of the sun 

 touched them, to notice an ebullition commence at once, which, 

 strangely, could be heard a few feet away. This ebullition was 

 continued for over an hour, growing less as thawing pro- 

 gressed. 



While holdiup; a mass of frozen frai^ments mv hand would 

 become quite wet with the melting ice. I am not in error in stating 

 that a cub. cm. of this fluid could have been easily saved had 

 the proper means been at had. It is much to be regretted that 

 none was preserved. 



I noticed some curious phenomena in a single fragment, which 

 had by some means escaped destruction by freezing. 



This specimen had several small cavities, arranged nearly 

 parallel to each other. At temperatures below 70° a small bub- 

 ble could be plainly seen to move in each cavity, as the position 

 of the specimen was changed. It was further noticed that the 

 cavities contained two liquids, in one of which the bubble was 

 wholly confined in its movements. This was seen to be the cen- 

 tral and more transparent fluid.
