tages of horizontal watertight compartments.—E. L. 
Bouvier ; New observations on viviparity in Australian 
Onychophores. It is shown that in spite of their 
name all the Ooperipatus are not oviparous.—M. 
Considére ; Deformation and fatigue of reinforced con- 
crete. Application to arched roofs. In the present 
state of knowledge it is impossible to calculate the 
total pressure at any given point of an arch.—Ph. 
Barbier and R. Locquin: The constitution of linalol. 
This alcohol was reduced by hydrogen at the ordinary 
temperature in the presence of platinum black. The 
resulting saturated alcohol was proved to be 
(CH,),.CH.(CH,),-C(OH)(CH;)(G3Hz). This leads to 
the constitution for linalol proposed by Tiemann and 
Semmler.—J. Guillaume; Observation of the occulta- 
tion of the planet Mars on May 30, 1914, made at the 
Observatory of Lyons.—J Guillaume ; Observations of 
the Zlatinsky comet (1914b) made at the Observatory 
of Lyons. Positions given for May 29 and 30. The 
comet appeared circular, about 2’ in diameter, and 
with a condensation round a nucleus of the 1oth mag- 
nitude.—Georges Meslin: The inclination of the spec- 
tral lines and the equatorial acceleration of the solar 
rotation. A revision and correction of a formula of 
Cornu.—Patrick J. Browne: A direct formula for the 
solution of an integral equation of Abel.—G, Armellini : 
The problem of two bodies of variable masses.—Léon 
Bouthillon and Louis Drouét: Experimental study of 
the telephone receiver. The theory explaining the 
sound produced by the telephone simply by the trans- 
versal vibrations of the whole membrane is in good 
agreement with the results given by experiment.— 
G. Gouré de Villemontée : The propagation of electricity 
through paraffin oil. The influence of the thickness 
of the dielectric and of charges of very short duration. 
—G. A. Dima: The initial velocities of the photo- 
electric electrons. An apparatus for determining the 
initial velocities is figured and described*in which the 
disturbing influences due to the reflection of light and 
the electrons are reduced to a minimum. The results 
for tin, zinc, aluminium, and magnalium are in agree- 
ment with*those of Richardson and Compton.—M. and 
Mme. Chauchard; The action of monochromatic ultra- 
violet rays on amylase and lipase from the pancreatic 
juice. The amylase is attacked only by rays with 
wave-length smaller than 2800, the action increasing 
very rapidly as the wave-length diminishes. Lipase is 
destroyed by rays for which A=3300, the amylase not 
being affected.cHenri Wohlgemuth: Researches on 
the acyclic y-halogen acids. These acids are obtained 
by the action of hydrochloric, hydrobromic, and 
hydriodie acids upon y-valerolactone. The yield and 
purity of the products depend on details of manipula- 
tion which are given in full. Examples of the 
chemical behaviour of these acids are also given.—M. 
Tiffeneau ; The migration of a methoxyl group in the 
course of the decomposition of a quaternary ammonium 
hydrate by Hofmann’s method.—G,. Chavanne and Mlle. 
J. Vos: The ethylenic isomerism of the acetylene 
di-iodides. A mixture of the two iodides was obtained 
by the action of acetylene upon iodine at 150°-160° C. 
From a study of the rate of elimination of hydriodic 
acid the cis configuration is attributed to the liquid 
isomer.—J. Giraud : New observations on the eruptive 
rocks of the south and west of Madagascar.—R. 
Fosse: The quantitative gravimetric analysis of urea 
in urine. The method is based on the insoluble com- 
pound formed by the interaction of urea and xanthydrol 
in acetic acid solution.—Emile Fleurent : Remarks on 
the diminution of the gluten in French wheats. Dis- 
cussion of a recent paper by M. Balland on the same 
subject.—L. and M. Lapicque and R. Legendre: The 
alterations of the myeline sheath produced by various

—C. Levaditi and A. Marie: The organism of general 
paralysis. Reasons are adduced for the view that 
there is a marked biological dissimilarity between the 
virus of general paralysis and that of cutaneous and 
mucous syphilis.—Pierre Thomas: The relations be- 
tween the proteid substances of yeast with sucrase.— 
A. Boutaric: The influence of the polarisation of 
diffused light by the sky on the values obtained for the 
solar constant. The value of the solar constant varies 
inversely with the polarisation. This invalidates the 
usual extrapolation for deducing the solar constant.—

| crushing of the Black River (Tonkin).

Royal Society of Tasmania, April 15.—Sir William 
Ellison-Macartney in the chair.—Prot. A. McAulay : 
Quaternions applied to physics in non-Euclidean space. 
1.—An outline of methods, for elliptic space and for 
hyperbolic space, to be used in subsequent papers.— 
J. H. Maiden: Notes on some Tasmanian eucalypts. 
In a paper read before the society in 1912, R. T. 
Baker and H. G. Smith proposed certain species on 
the basis of essential oils obtained by distillation. The 
author criticises these species, and discusses the rela- 
tions between essential oils (and other accessory char- 
acters) and the species which yield them.—H. Stuart 
Dove: Stone implements used by the aborigines of 
Tasmania. The author describes some examples of 
the disc-shaped stones, sometimes called ‘‘ hammer- 
stones,’’ found in the middens of the extinct aborigines 
of Tasmania, and discusses their use.
