| Title | Unpublished paper, 'Researches to determine the number of species and the mode of development of the British triton' by John Higginbottom |
| Date | February 1847 |
| Description | Higginbottom writes that two species only of the genus Triton exist in England; namely, the Triton verrucosus and the Lisso-triton punctatus. It is three years before the animal is capable of propagating its species, and four years before it attains its full growth. In its tadpole state, it remains in the water until its legs acquire sufficient strength to qualify it for progressive motion on land. While a land animal, it is in an active state during the summer, and passes the winter in a state of hibernation; but does not then, as has been erroneously supposed, remain at the bottom of pools. Very dry, or very wet situations are incompatible with the preservation of life during the period of hibernation. At the expiration of the third year, the triton revisits the water, in the spring season, for the purposes of reproduction, and again leaves it at the commencement of autumn. Impregnation is accomplished through the medium of water, and not by actual contact. The growth and development of the triton are materially influenced by temperature, and but little by the action of light. The triton possesses the power of reproducing its lost limbs, provided the temperature be within the limits of 58 and 75 degrees Fahrenheit; but at lower temperatures, and during the winter, it has no such power.
Annotations in pencil throughout. Followed by four pages of figures of tritons with descriptions.
