that of the five pits examined by Mr. Horner was found to 

 vary from 1206*11 to 1174*71 J and on evaporation afforded 

 from 2289*75 grs to 1922*97 grs of entire salt, dried at ISO* 

 Fahr., in a pint* 



This salt, from a careful analysis, appears to be composed Thesak 



of

On comparing the brine of Droitwich with that of Droitwich and 

 Cheshire, as described by Mv.Hollaad in his Agricultural Sur- P? 15 ***? 

 vey of Cheshire, and by Dr. Henry in his paper on the sub- compared, 

 ject in the Philos. Trans., it appears, that the strength of the 

 different brines is nearly the same, that the Cheshire brine 

 contains rather a larger proportion of muriate of soda, that 

 the Droitwich brine is free from carbonate of lime, oxide of 

 iron, and muriate of lime, all of which are found in the 

 Cheshire brine ; and finally, that the latter is free from the 

 sulphate of soda, which is contained in the former.
