CrLoups (Cirrus, Hic Croups). 
390. A Gentle Breeze. Hon. Duff Tollemache, 
Form and colour of the cirrus cloud very natural. 
505. Fifteen-metre Yachts Rounding the East Lepe 
Buoy: Cowes Regatta. Alice Fanner. The cirrus 
cloud in this seascape is very good. The small cumuli 
and wisps of cirrus very natural. 
NATURE 
689. Six-metre Yachts Racing at the International | 
Regatta, Solent, 1911. Alice Fanner. The cirrus 
clouds are well represented. 
SUNSETS, SUNRISES (SKy). 
13. Scur-na-Gillian, Sligachan. Finlay Mackinnon. 
A beautiful picture with a bold effect of sunset. Is 
not the near side of the right-hand peak too much 
illuminated ? ‘ 
55: Evening on the Sands of Towyn. 8B. W. 
Leader, R.A. A fine sunset sky; shape and colour 
of clouds very true. Reflection in water and break- 
ing wave very effective. A fine picture. — 
147. “‘The Day was Sloping towards his Western 
Bower.” Joseph Farquharson, A. Have we not here 
a too great diversity of colours? Should not the 
yellow tinge be more universal and be more repre- 
sented on the hill on the left (which seems too pink) 
and also on the under portions of the clouds? 
205. Evening’s Last Gleam. B. W. Leader, R.A. 
A fine study and lighting excellent. The sunlight on 
the upper portion of the clouds very effective. 
429. The Matterhorn, from the Triftkummen: Sun- 
rise. Edward T. Compton. The colours here are 
very true in tone, and the wisps of mists on the 
mountains appear already to be in the process of being 
dissipated. ; 
465. The Prize. Donald Maxwell. A bold picture. 
Very striking sunset effect, both in the sky and by 
reflection, Excellent colouring. ; 
669. A Peaceful Valley. Hon. Walter James. This 
sunset scene is accurately painted, and the cloud 
forms, colouring, and general gradation of the tones 
very true. The atmospheric absorption in the distant 
landscape naturally indicated. 
790. Into the West. Robert W. Allen. The 
sequence of the colouring at the different altitudes 
very natural. The type of cloud represented is true, 
but there is not sufficient of the sunset colours re- 
flected in the water. 
Sun’s Disc. 
29. The Wane of an Autumn Day. J. Coutts 
Michie. The disc of the sun is very much too large, 
and, judging by the angles subtended by the objects 
in the foreground, it is more than twice the size it 
should be. 
Moon. 
353- Moonrise: the Dunes, Pas-de-Calais, France. 
H. Hughes-Stanton. The full moon much too large, 
judging by the trees in the foreground. 
369. Moonlight on the Cornish Riviera. R. Borlase 
Smart. Moon too large for similar reasons; also sky 
around the moon too blue. 
782. Moonrise over the Marsh. Stuart Lloyd. The 
moon here is more natural, but still a little too big 
judging by the trees in the foreground. 
122. Evening. William Brock. In this picture 
only a small portion of the upper part of the moon 
is seen above the horizon. By its horizontal extent 
and curvature it is very much too large, and calcula- 
tions suggest that if the whole disc were visible it 
would be three or four times too large. 
123. Twilight. Fred Hall. The size and colour of 
the moon are good. The woman and cattle in fore- 
ground are perhaps too much illuminated. 
151. An Autumn Evening in the Alps. Adrian 
NO. 2219, VOL. 89] 
245 
| 
' Stokes, A. The sun is here supposed to be below the 
| horizon on the right, consequently the visible illu- 
| minated portion of the moon ought to be leaning 
slightly over to the right also, and not as shown. The 
| clouds are also too bright relative to the moon. 
Rainsow. 
468. The Home Port. W. Ayerst Ingram. This 
would be a fine picture if the rainbow were omitted. 
| The sun is setting on the right of the picture more 
than 90° away from the observer. This can be 
gathered from the position and sunlight on the ship 
in the centre of the picture and other illuminated 
objects. As one of the fundamental conditions for 
| seeing a rainbow is that the sun should be at the 
back of the observer, it is not possible for a rainbow 
to be included in the picture under the existing sunset 
position. 
REFLECTIONS. 
167. A Little Mishap. Sir E. J. Poynter, Bart., 
P.R.A. An excellent study of reflections. 
Wituam J. S. Lockyer. 
INTERNATIONAL ASSOCIATION OF 
CHEMICAL SOCIETIES, 
HE International Association of Chemical 
Societies held its first formal meeting in 
Paris in April, 1911, when the delegates 
nominated by the French, German, and English 
Chemical Societies met and ratified the statutes 
of the association, the council of which as at first 
constituted consisted of Profs. Béhal, Hanriot, 
and Haller representing the Société Chimique de 
France, Profs. Jacobson, Ostwald, and Wichel- 
haus representing the Deutsche chemische Gesell- 
schaft, and Profs. Frankland, Meldola, and Sir 
Wm. Ramsay representing our Chemical Society. 
The second conference was held in Berlin last 
month, under the presidency of Prof. Ostwald 
and the vice-presidency of Prof. Wichelhaus, 
when the council was further enlarged by the 
addition of Profs. Carrara, Oglialoro, and Paternd 
representing the Italian Chemical Society, Profs. 
Kurnakow, Tschugaeff, and Walden representing 
the Russian Chemical Society, Dr. Day and Profs, 
Noyes and Richards representing the American 
Chemical Society, and Profs. Fichter, Guye, and 
Werner representing the Swiss Chemical Society. 
Certain other societies representative of Holland, 
Denmark, Austria, and Norway were also 
affiliated, but were not directly represented on the 
council. Prof. Meldola, having been unable to 
attend the meeting, withdrew from the repre- 
sentation of the Chemical Society, and was re- 
placed by Prof. Crossley. 
The first work of the Association is the con- 
sideration of the nomenclature of inorganic and 
organic chemistry and the unification of the nota- 
tion of physical constants. In connection with the 
latter part of the programme, the committee has 
been strengthened by the addition of M. Marie, of 
the French Society of Physical Chemistry. The 
English committees appointed to report upon 
these preliminary branches of work are, for in- 
organic nomenclature, Sir Wm. Ramsay, Dr. 
J. C. Cain, and Dr. Harden; for organic nomen- 
clature, Profs. Kipping and Wynne and Dr.
