of the species, descriptions of several new species and varieties, 

 a complete table jhowing the distribution of the genus, and de- 

 scriptions of the genitalia.- — Among other communications was 

 one from the Rev. H. S. Gorham, containing a list of the 

 Coleoptera of the family Clerida: collected by Mr. Doherty in 

 liurmah and Northern India, with descriptions of new species ; 

 and an account of some species of the same family from Borneo, 

 Perak, and other localities, in the collection of Mr. Alexander 

 Fry. Twenty-eight species were described as new. — Prof. G. 

 B. Howes read a paper on the coracoid of the terrestrial verte- 

 brates. Prof. Howes first spoke of the terminology of the bone 

 commonly called "the coracoid," and then proceeded to the 

 discussion of the mammalian coracoid in particular. He came 

 to the conclusion that it would be best to call the whole ventral 

 coracoidal bar the "coracoid," and to distinguish the doubly 

 ossified type as " bicoracoidal " from the singly ossified or 

 "unicoracoidal " type. — Lieut.-Col. H. H. Godwin-Austen, 

 F.R.S., read the descriptions of some new species of land- 

 shells of the genus Alycccus from the Khasi and Naga Hill 

 countries, Assam, Munipur, and the Ruby Mine district. Upper 

 Burmah. — This meeting closed the present session. The next 

 session (1893-94) will commence in November.

Academy of Sciences, July 3. — M. Loewy in the chair. — 

 Tidal and atmospheric waves due to the action of the sun and of 

 the moon, liy M. Bouquet de la Grye. The results are given 

 of a series of determinations of the tides, barometric pressures, 

 and winds made by a French commission at Orange Bay, Cape 

 Horn, ranging at half-hourly intervals from November I, 1882, 

 to August 31, 1883. A first study of these results confirms the 

 facts, announced previously, relating to luni-solar influence 

 upon the atmosphere. This action is very apparent at Cape 

 Horn, since the w ater and air at lat. 56° south have a uniform tem- 

 perature at any given date, and the annual range of temperature 

 is very small. — On the successive deformations of the front of an 

 isolated air wave, during the propagation of the wave along an 

 indefinitely long empty » a' er-pipe, by M.J. Boussinesq. — On 

 birationaltransformationsof algebraic curves, by M. H. Poincare. 

 — On the observation of the total eclipse of the sun of April 16, 

 made at Joal (Senegal), by M. A. dela Baume Pluvinel. — On a 

 self-registering hydrokinemometer, by M. Clerc. This consists 

 of two vertical cylinders communicating with the water at the 

 stem and the stern of the vessel respectively. The difference of 

 level in the two cylinders is proportional to the square of the 

 velocity with which the boat is travelling. The cylinders are 

 provided with floats, each of which takes a share in actuating 

 the recording pencil, with which they are connected by strings 

 passing over pulleys, disposed in such a manner as to let the 

 record be unafifecting by any heeling or plunging of the boat. —

 de Mas. — Radiation of different refractory bodies, heated in the 

 electric furnace, by M. J. Violle. — Auto-conduction, or a new 

 method of electrifying living beings ; measurement of magnetic 

 fields of high frequency, by M. A. d'Arsonval. — Additional 

 remarks by M. Cornu. — On chromopyrosulphuric acid, by M. A. 

 Recoura. After showing that the molecule of chromic sulphate 

 can be combined with one, two, or three molecules of 

 sulphuric acid, M. Recoura has succeeded in combining 

 the sulphate with a larger quantity of acid, and has ob- 

 tained new compounds presenting properties completely 

 different from those of the three former acids, and characters 

 not found in any other chromium compounds. One of these, 

 "chromopyrosulphuric acid," contains five molecules of sul- 

 phuric acid. — Constitution of the colouring matters of the
