Proceedings of the Royal Society for the month of April, 1879

A monthly meeting of the Society, the first of the session, was held on Tuesday, the 8th April. James Barnard, Esq., in the chair.
The following note to the Secretary, from Mr. Brown, was read in relation to sending a few geological specimens from Hicks' Island, New Britain. This island was thrown up by a submarine volcano. I landed on the island and picked up the specimens before it was a week old, so they had not much exposure to the weather.
From Mr. S. H. Wintle :—Fossils from the west bank of the Tamar at Rosevear; were presented to the Society. In reference to this presentation the following note from Mr. Wintle was read :—"When in Hobart Town recently, I left with Mr. Roblin a few fossils, etc., and promised him that I would write a letter respecting them.
"The specimens in question I found on the west bank of the river Tamar, at Rostreavor, at low water mark. They had been washed out of a tertiary clay deposit by river action, and were associated with numerous fossil fresh water mussels (Unio). The small slab of indurated clay, it will be seen, is of much palaeontological interest on account of its presenting on one side an impression of the tongue-fern [Glossopteris), a cryptogamic fossil, which is typical of the Australian carboniferous period, while on the reverse side appears an external cast of a bivalve shell, which I am unable to identify, but which I cannot regard as an Unio. In all probability it is that of a marine shell. Accompanying it is an internal cast of what appears to be the same species of testacea.
Several important donations to the library were noted: From Dr. Milligan, F.L.S Jardine's Memoirs of Hugh Strickland.
