The first part of this memoir gives the results of experiments made by Daubree, 

 with a view of imitating the processes by which Nature may have acted in forming 

 minerals. Instead of using fluorides, which are not so easily prepared, Daubree 

 generally employed chlorides. From the great analogy of fluorides with chlorides he 

 considers that the results obtained with the latter may be safely supposed to occur 

 with the former. The first experiment consisted in passing a current of stannic 

 chloride and a current of steam into a red-hot porcelain tube. Double decomposition 

 took place, and crystals of stannic oxide were deposited on the sides of the tube. 

 The crystals were found to belong to the rhombic system, which shows that stannic 

 oxide, like titanic oxide, is dimorphous. The temperature of the end of the tube, 

 * where the crystals were deposited did not exceed 572° F. (300° C), or, in other words 

 was rather less than the melting point of lead. Titanic chloride, treated in the same 

 way, gave crystals of brookite; whilst a deposit of vitreous and in part crystallized 

 quartz was obtained from chloride of silica and steam. — 0. Le Neve Foster.
