Laboratory Fresenius at Wiesbaden, Germany, has recently passed the fiftieth year of its existence and its hundredth term, it having been founded on the first day of May, 1848. Since the death of its founder. Prof. C. Remigius Fresenius, June 11, 1898, it has been carried on by his sons. Dr. Heinrich Fresenius and Dr. Wilhelm Fresenius, and his son-in-law. Dr. Ernst Hintz, and is to be continued as before. The attendance at the winter session, 1897-'98, was equal to that of former years.

theories have been proposed iu the attempt to explain the apparent enlargement of the sun and moon when near the horizon. M. D. Eginites, having compared the principal of them, finds none satisfactory, and that the phenomenon is not produced by any of the causes they assign. Any or all of these causes may contribute more or less to it, but not in any great degree, and the real cause is still to be sought.

—Ma de los Muertos—at San Pedro, in southern California, a place of historical and scientific interest, is described by Mrs. M. Burton Williamson as "a vanishing island," the whole facies of which has been changed within a few years by the erosive power of waves and tides and winter rains. A few years ago the west side of it could not be reached except by way of the inner harbor or by climbing to the top of the island and descending a precipitous trail. Now the sea has cut an arch through the solid rock, and one can go all round the island at low tide. Within the recollection of persons now living it has diminished in area one half or more. In science it is famous for its fossil shells (Pliocene and Quaternary), of which three hundred species have been found. Some of these have been identified with species still living in the coast waters farther north.

tender shoots of ferns may be sporadically eaten among us, but nowhere that we know of dj they form a regular article of diet in E trope or America. In Japan it is different, according to the Bulletin of the French Jardin d'Acclimatation, and some of the mountain people derive a large proportion of their food in some seasons from ferns. In the spring they eat the young leaves; later in the season, the starch which they extract from the roots. For this extraction they beat the washed roots with a mallet, stir the fragments in water, and precipitate the starch, using for reservoirs in the operation hollowed tree trunks. The starch obtained is equivalent to fifteen per cent of the root stuff used.

buffalo tree hopper is a little grass-green insect of triangular shape which is frequently found upon vegetation, and displays considerable agility in leaping when discovered. It gets its peculiar name from a supposed similarity in shape to the male buffalo. Its thorax is very wide in front, projecting in two strong horns at the sides, and is triangular, leaving the insect relatively very narrow in the rear. The hopper does great damage in orchards and gardens, through the cutting up of the limbs by the female in depositing her eggs. C. L. Marlatt, of the Department of Agriculture, has published a circular relating to it.
