by whom taken (if not by myself), or how it came into my possession, with any other particular worthy of note. With all eggs received in exchange or otherwise, this note should, if possible, be obtained in the handwriting of the person from whom they are received, and the slip on which it is written be affixed in the book under the number. When specimens of the eggs of the same species are obtained from various localities, those from each locality should be distinguished by a letter prefixed to the number. The plan will be better understood by referring to the following extract: 62. Great Sedge-warbler (_Sylvia turtoides_, Meyer). 62. Received of ----, from the cabinet of Mr. ----. a62. Taken by ----, a servant of ----, on the banks of the river Tougreep, near Valkenswaard, in the south of Holland, on the 9th of June, 1855. The birds may be heard a long way off by their incessant "Kara, Kara, Kara." A few years ago not one was to be found near Valkenswaard. A. B---- b62. Bought at Antwerp in August, 1865. X/ * * * * * 118. Mealy Red-pole (_Fringilla borealis_, Tem.). 118. Nyborg, at the head of Mæsk Fjord (one of the two branches into which Varanger Fjord divides), East Finmark, Norway, July, 1855. The birds were very plentiful, and only one species seen, which appears quite identical with that which visits England every winter. C. D. E---- By means of these entries, and the corresponding number on the egg, mistakes are impossible, and the name and history of each egg would be quite as well known to a stranger as to the possessor. It needs not to be said that this catalogue is replete with the deepest interest to its compiler. In it he sees the record of many a holiday trip and many a successful find. Some of the entries in my own register--the earliest date back five-and-twenty years--are memorials of companions long since dead, or separated by rolling oceans, but on whose early friendship it is a pleasure to dwell. Nothing can be more vexatious and disappointing than the receipt of a box of valuable eggs in a smashed or injured condition from want of care or knowledge of the proper method of packing. A simple method is recommended by Professor Newton, which, from experience, I can confidently recommend:--Roll each egg in tow, wool, or some elastic material, and pack them closely in a stout box, leaving no vacant place for them to shake; or a layer of soft material may be placed at the bottom of the box, and upon it a layer of eggs, each one wrapped loosely in old newspaper; upon this another layer of wool or moss, then again eggs, and packing alternately until the box is quite full. Bran, sawdust, &c., should never be used; and it should be ascertained that the box is quite filled, so that no shaking or settlement can occur.
