800 Specimens of the Soil and Salt from [Dec. 



4. A piece of ditto, on which, apparently, the salt did not come out well. 



5. A piece of ditto, near the edge on which the salt did not form. 



6. A piece of ditto, the salt of which got mixed with scum while forming. 



7 - A piece which seems to have heen similarly mixed, but which was cut 

 from another kiyar, and said to he five or six years old. It has evidently been 

 raiued upon, and it was taken from under a sheet of rain water, by whicu more 

 of it would have been melted had it not been old and pakka. 



8 a. — A piece on the scum of which crystals were formed after rain had fallen 

 upon it. 



8 b.— A ditto ditto. 



8 c. — A ditto ditto. 



9. A piece the salt of which got somewhat mixed with mud when being 

 formed, (probably from its being agitated by a strong wind) and on which a 

 crust of scum settled. 



10. A piece of crust, chiefly scum, such as is thrown aside as useless. 



11. Other refuse pieces taken from a kiyar in which they had been lying 

 neglected for, perhaps, some years. 



12. Pieces of crust of salt from the surface of a kiyar. 



13. Ditto ditto. N. B. These have been more or less smoothed and thinned 

 by having been rained upon. 



14. Bits of a fine crust of salt with a little scum on. the top. This was cut 

 with a phaura from the surface of a kiyar. 



14 a. Three other bits of a different kiyar. 



14 b. Another of another. 



The above five items are merely varieties to enable you to trace the process 

 of formation. 



A 15. — " Bachek, ,y or infant crystals, about the smallest size in which the 

 mineral particles come to view on the surface of the salt mud, after the partial 

 evaporation of a body of water covering it. These were taken from under a 

 sheet of water six fingers (or three inches) deep. 



16. Crystals about two days old (after first formation) six fingers' depth of 

 water at first, 1§ fingers' depth evaporated when crystals taken out. 



17. Ditto about three days old ; or when two of six fingers' depth of water 

 had evaporated. 



18. Ditto about four days after first formation, or when three of six fingers' 

 water had evaporated. 



19. Ditto of a fair (common) size, produced after about eight days' evapora- 

 tion of six fingers deep water. — N. B. These crystals were found during the hot 

 winds, when the day's heat was intense, and that of the night considerable. 



20. Crystals which formed on a stick after it had lain seven days in the six 

 fino-er water from which the last mentioned (19) were taken after eight days. 



21. Ditto. The concretion is more rapid on a thread, or stick, or any thing 

 that the water can get round, than on the surface of the mud. 



22. Crystals made in a kiyar in 20 days during the hottest season. 12 fingers' 

 depth of water at first, four remaining when crystals were taken out. 



23. Crystals taken from the lake after a complete and uninterrupted evapo- 

 ration of a body of water five or six, or perhaps more, inches deep. 



24. Pink crystals from the surface of the marsh ; formed by the rapid eva- 

 poration of a shallow deposit (or puddle) of water.
