Summary:
Corrects a misunderstanding of his description of salt deposits [in South America, pp. 74–5]. The salt referred to was from Rio Negro, and was coarsely crystallised and free of other saline substances found in sea-salt. CD believes its lesser value in curing meat is owing to the absence of muriates of lime and magnesia and suggests that it might be worth while to add them to the Rio Negro salt.
