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

The monthly evening meeting of the Society was held on Monday, 8th September; His Lordship the Bishop of Tasmania in the chair.
Attention was called to a valuable work by Baron F. Von Mueller, K.C.M.G., entitled "A Descriptive Atlas of the Eucalypti of Australia and the adjoining Islands," copies of the first and second parts of which had been presented by the author on the part of the Government of Victoria.
The following communication on the Codling Moth from the Department of Agriculture, America, was read by Mr. Abbott, who observed in the first instance that although little new information as to the moth was brought forward, the paper was valuable as pointing out the great benefit which was likely to accrue from united action being taken to suppress the pest in any given district.
In the absence of the author, the Secretary read a paper of considerable scientific interest, by Mr. E. M. Johnston, F.L.S., entitled "Notes on the relations of the Yellow Limestone (Travertin) of Geilston Bay, Hobart Town, with other fluviatile and lacustrine deposits in Tasmania and Australia, together with descriptions of two new fossil Helices."
