being apparently filled by another species* of the same genus, I have 

 little hope of your discovering it. 



With regard to the internal parts of animals ; those of Vertebrata 

 should be preserved, as well as the animals 'themselves of those Inverte- 

 brata which are provided with a shell. Of the importance of these in 

 systematic classification you are well aware. 



The little time I can command must be my apology for not entering 

 here upon the subject of the preservation of your specimens. All I 

 know, however, about it is fully detailed in a paper I published last year 

 in the Journal of the Asiatic Society ; a copy of which 1 have the plea- 

 sure to annex. In that paper you will find the method I have been 

 induced, by the experience of several years in this climate, to recommend, 

 and which has been practised in my own cabinet, and in the museum 

 of the Asiatic Society, with the most perfect success. 



In conclusion, permit me to congratulate you upon an appointment 

 which promises so fair an opportunity of distinction to yourself; and 

 such great advantage to zoological science.

The Noh Mehdl situated below and to the east of the Mewdt hills, 

 and between two j heels, that of Kotela to the south and that of Chun-

The area of these villages is about 39J square miles. 



The salt is made by solar evaporation from well water, exposed in 

 pukka vats or reservoirs of an average of 3 J cubits deep, 70 cubits long 

 and 40 cubits broad. These reservoirs are built in sets of six, and are 

 filled from wells, one of them is chosen which is always kept full from 

 the remaining five, while these again are refilled from the well as often 

 as they empty. 



Two years is the usual time for the first collection of salt (this if 

 however often retarded or accelerated by a heavy or scanty fall of rain, 

 during the wet months) : when a red scum begins to appear on the sur- 

 face of the water fresh bushes are thrown in, chiefly of thorny plants, 

 such as the Keeker, Jhoud, Joankur and the Joasa plants, and by the 



* Further reflection has led me to think the Sylvestre, or C. Tomentosus is a variety 

 of and not a distinct species from the C. cacti.
