Vice-President, in the chair.—Dr. Harvey Gibson read the 
second part of his paper on ate//a.—Prof. Tait read a paper by 
the Rev. T. P. Kirkman on the unifilar knots with ten crossings ; 
and also a paper of his own on the census of ten-fold knotti- 
ness. There are 364 different forms of ten-fold knottiness, 
when the crossings are alternately over and under, included in 
124 types, 50 of which are unique, while 74 have multiple 
forms.—Prof. Tait also communicated a paper by Messrs. 
Crocket and Creelman on the thermal effects produced in solids 
and in liquids by sudden large changes of pressure, and a paper 
by Mr. W. Peddie on a method of determining the resistance of 
electrolytes without endeavouring to prevent polarisation.— 
Prof. MacFadyean and Dr. G. S. Woodhead submitted an 
account of the construction of the auricles of the pig’s heart. 
Beating of the heart and the superior vena cava may continue 
under proper stimulation for a few hours after death.--Mr. A, 
P. Laurie communicated a note of the heat of solution of zinc 
iodide. The heat of solution was determined by observations 
of the electromotive force of a voltaic cell invented by himself 
for the purpose.—Dr. J. McFarlane read a second paper on 
pitchered insectivorous plants.—Mr. H. R. Mill, of the Scottish 
Marine Station, read a paper on the salinity of the Tay estuary 
and of St. Andrew’s Bay.—The meeting, which was the last for 
the session, was concluded by an address from the chairman. 
PARIS 
Academy of Sciences, August 10.—M. Bouley, President, 
in the chair.—Note on the chief momenta of terrestrial inertia, 
by M. F. Tisserand.—Remarks on the third part of the Map of 
Tunis, published by the French War Office, and presented to 
the Academy by Col. Perrier. The map is to the scale of 
I: 200,c00, and the present sheets comprise the districts of 
Gafsa, Maharés, Kebili, Gabés (Cabes), and Zarzis. Three 
sheets only remain to complete the whole work, and for these 
the surveys have already been made.—The sixth part of the 
General Map of Africa, executed for the War Office to the scale 
of I: 2,000,000 by Capt. de Launoy. This part contains eight 
sheets comprising the districts of Tabora, Zanzibar, Livingstonia, 
Vicloux, Mossamedes, Linyanti, Tete, Quilimané.—Note on a 
registrar of the calorific intensity of solar radiation (one illustra- 
tion), by M. A. Crova. The apparatus here described is 
intended faithfully to record the readings of an actinometer 
giving the calorific intensity of solar radiation to which it 1s 
directly exposed, while protected from the disturbing action of 
the winds.—On the treatment of mildew (Peronospora vitis) by 
means of sulphurous acid, by M. Emile Vidal.—A’ certificate, 
prepared by Dr. Ferran and signed by several physicians, 
respecting the results of anti-choleraic inoculations at Benifayo, 
accompanied by a diagram showing the progress of the 
epidemic before and after these inoculations, was presented 
to the Academy, by M. F. Angla. Similar documents 
are promised for other districts. A telegram was also received 
from M. Paul Gibier regarding the experiments made by him 
with hypodermic inoculations of the cholera bacillus.—Observa- 
tion on Tuttle’s comet, the return of which was noticed on 
August 8 and 9 by M. Perrotin at the Observatory of Nice. — 
Remarks on a demonstration of the law of reciprocity in mathe- 
matical analysis, by M. A. Genocchi.—On the temperatures and 
critical point of pressure for the chloride of ethyl, and another 
series of homologous bodies comprising ammonia, gas, and the 
three methylamines, by MM. C. Vincent and J. Chappuis. —On 
aqueous evaporation in a disturbed state of the atmosphere, 
by M. Houdaille. —On a method of obtaining a true 
standard volt; cause of previous errors, by M. A. Gaiffe. 
—Products of the oxidation of carbon by the electrolysis of 
an ammoniacal solution, by M. A. Millot.—On certain alloys of 
cobalt and copper, by M. G. Guillemin. The alloy with 5 per 
cent. of cobalt is described as specially interesting, being capable 
of resisting oxidation, malleable as ordinary copper, tenacious 
and ductile as iron. It might be largely used in the 
manufacture of rivets, tubes, and a great variety of copper- 
ware articles in daily use.— On the thermic phenomena 
attending the transformation of the protochloride of chromium 
into a sesqui-chloride, by M. Recoura.—On the crystallo- 
graphic characters of the substituted derivatives of camphor,

Expedition, by M. Edmond Perrier.—Position of the embryo 
and formation of the cocoon in Periplaneta orientalis, The 
author describes the results of his observations, continued 
throughout the whole formation and evolution of the egg of this 
insect for the purpose of determining the exact relations existing 
between the organic axis of the egg, the principal axis of the 
embryo, and that of the maternal organism.— On the local treat- 
ment of fibrinous pneumonia by means of intra~parenchymatose 
injections, by M. R. Lépine.—On the cystitis and nephritis pro- 
duced in the healthy animal organism by the introduction of the

man, its cultivation and inoculation, by M. Tayon.—Transmis-

Koubassoff.—An explanation of the abnormal development of 
the grape occasionally occurring in the’ vineyards of the Vaudois 
district, by M. J. B. Schnetzler.—On a specimen of pine found 
embedded in the upper Tschingel glacier at an altitude of 2475 
metres, far above the present zone of the pine in this region, by
