| Title | Unpublished paper, 'On the formation or secretion of alkaline and earthy bodies by animals' by Robert Rigg |
| Date | 6 January 1845 |
| Description | Rigg aims to show that alkaline and earthy bodies are secreted by animals. From the results of a comparison of the weight of the ashes obtained from a quantity of bread, equal to that which was the sole food of two mice during thirty-eight days, with the weight of the ashes of their excretions during the same period, it appeared to Rigg that the latter exceeded the former in the proportion of 1334 to 934. The amount of soluble salts was also found to be greater in the latter than in the former. From these data, Rigg infers that both alkaline and earthy bodies are formed out of their elements by the animal system, and found in their excretions.
