moved: "That associations of manufacturers and producers should confer together with the British Association of Trade and Technical Journals in order to formulate a consistent policy in regard to such matters as the advertising of enemy and neutral goods after the war and the attitude that should be adopted towards importers and factors of such goods," said that it was necessary for each association to consider after-war relations with our present enemies. The publicity power of the trade journals was at their service, but the Press would reflect the policy adopted by these associations and by the Government.

Mr. HORACE WYATT (Association of British Motor and Aircraft Manufacturers), in seconding the resolution, claimed that the Press should not reflect the views of the country or of sections, but should give a lead. He would like a policy to be formulated that all journals would adopt provided the manufacturers gave corresponding guarantees.

Sir GEORGE MAKGILL, Bart. (British Empire Producers' Organisation) approved of further conference, and sug. gested that it might be expedient to have a higher scale of charges for advertising neutral and enemy goods somewhat proportionate to the proposals of the Paris Conference.

Mr. OTTO THOMAS (Motor Traction) appealed for a strong declaration of policy, regardless of minor practical difficulties which would have to be considered and overcome later.

Mr. D. N. DUNLOP (British Electrical and Allied Manufacturers' Association) said that it would be fair to expect that if the rejection of enemy advertising meant a serious sacrifice of revenus on the part of the members of the Association of Trade and Technical Journals, the Association of British Manufacturers should in some way make that good. He saw great possibilities in further con ference.

Mr. HERBERT WILLIAMS (Machine Tool Association) said that whatever plan might be adopted they would have to meet certain practical difficulties such as the purchase by enemy interests of weaker journals which might be converted to the service of alien firms.

which are best left to skilled hands. The directions are clear and full, and the average student would probably have no difficulty whatever in carrying out the experiments and calculating his results without any help from a teacher. The volume includes 59 experiments in heat and 68 in light, and the whole ordinary course of elementary work is covered. The experiments are, as a rule, of the usual type, and display no particular novelty, but they represent a very useful collection, designed to give the student a thorough working acquaintance with the clementary principles of heat and light.

Chemistry for Rural Schools. By ERNEST JONES, M.Sc., and J. JONES GRIFFITH, B.Sc. London, Glasgow, and Bombay: Blackie and Son, Ltd. 1916. Pp. 184. Price 2s. 6d. net.

THIS book is intended to be used as a theoretical and practical introduction to agricultural chemistry for students in technical schools and agricultural colleges, and at the same time the authors believe that it may be found useful for general students who are beginning chemistry, but do not mean to specialise in scientific agriculture. The early part of the book describes the usual operations of elementary practical chemistry-measuring, weighing, and the study of chemical and physical changes-and then the chemistry of the atmosphere is taken up, followed by experiments on oxygen, acids, hydrogen, and salts. Some account is given of the laws of chemistry and of the atomic theory. In the later part of the book, which deals with the common elements and their compounds, the experiments are mostly chosen with a view to the application of the student's knowledge to the problems of agriculture, and such subjects as the fixation of atmospheric nitrogen, the assimilation of carbon dioxide by plants, animal nutrition, the constituents of the soil are discussed in outline with illustrative experiments. Most boys and girls would find the course of work described interesting, and the spread of the kind of knowledge it imparts is of vital importance at the present moment. The book appears a satisfactory pioneer of the new movement of which signs are to be discerned in recent discussions re

Mr. VICKERS (Indian and Eastern Engineer), Mr. DODD (Canadian Machinery), and others followed.

The resolution was carried unanimously.

At a meeting of the Council of the British Association of Trade and Technical Journals, on December 18, it was decided to invite the following gentlemen representing associations of manufacturers:-Sir George Makgill, Bart.,

Sir Chas. Bedford, Messrs. D. N. Dunlop, H. Williams, H. Wyatt, and R. T. Nugent to meet a sub-committee to consider what practical steps can be taken for the more effectively organised co-ordination of British production and publicity,

NOTICES OF BOOKS.

Practical Experiments in Heat and Light. By W. ST. B. GRIFFITHS, B.A., B.Sc., and P. T. PETRIE, M.Sc., Assoc. M. Inst.C.E. London: Rivingtons. 1916. Price -One vol., 3s. 6d. net; or, in two Parts, "Heat," 28. net; "Light," Is. 6d. net. Pp. iv. +123; viii. +112. THIS book appears to be a thoroughly useful guide to experimental work in heat and light. It contains descriptions of such experiments as can be performed by young students themselves with the apparatus usually to be found in the average well-equipped physical laboratory, no lecture table experiments being included, nor any

chosen their material sensibly, and have not attempted too much, and the wide adoption of the book in rural schools would be a decided step forward in the right direction.

The International Movement of Fertilisers and Chemical Products Useful to Agriculture. Rome: The International Institute of Agriculture. 1916. Pp. 76. Price 1.50 fr.

THIS reprint from the "International Crop Report and Agricultural Statistics" appears very opportunely at the It gives full and detailed information present moment. relating to the production, trade, consumption, and prices of all important chemical fertilisers and also sulphur and copper sulphate. Most of the trade statistics are official, and every effort has been made to make the data relating to the consumption in various countries as full and accu rate as possible. A useful bibliography of the world's literature on the subject of artificial fertilisers is included.

Literary Intelligence. Mr. Lloyd George has accepted the dedication to Mr. Arthur Marshall's celebrated book on Explosives. The second edition, much enlarged, will appear in two volumes-the first of which will be ready immediately, and will contain a hand. some portrait of the Prime Minister. Mr. Marshall's book is the only recent treatise in the English language on a subject which is of national value at the present time Messrs. J. and A. Churchill are the publishers.

OBITUARY.

MR. ANDREA ANGEL.

THE death of Mr. Andrea Angel, M.A., F.C.S., B.Sc. (Oxon.), who heroically sacrificed himself in the explosion at the munitions factory near London, on Friday, January 19th, is a great loss to chemical science and will be very deeply lamented by his colleagues and his wide circle of acquaintances and friends. When the fire broke out he, perhaps more fully than anyone else, realised the terrible danger of explosion, but with the utmost self-forgetfulness and devotion to duty he did his best to warn others and to fight the conflagration, and thus went to his death without flinching.

Mr. Angel was born at Bradford, Yorkshire, in 1877; He received his education at Exeter Grammar School and at Christ Church, Oxford, taking a first-class in Chemistry in 1899. He took his M.A. degree in 1903 and B.Sc. in 1906. He was appointed Lecturer in Natural Science at Brasenose College, Oxford, and tutor to the non-collegiate students, and his success as a teacher was remarkable, many of his students having reason to be thankful that they had the advantage of coming under his stimulating influence. A short time ago he became chief chemist at the factory at which the explosion occurred, and there he exhibited the same thoroughness and assiduity

which had marked his work as a teacher.

different theatres of operation had been largely increased, the total quantity of wine requisitioned by the Government of the Republic is estimated at 6,000,000 hectolitres, representing one thousand one hundred and eighty-eight million half litres=792,000,000 large bottles. In the opinion of the Medical Staffs of the French Armies, the daily consumption of wine has contributed in a very material degree to the magnificent health which all ranks have enjoyed since the beginning of the war. This is particularly apparent on the Eastern front, where we understand that the example has been followed with equal advantage in the case of the British troops. The experience also confirms that obtained upon our own Chateau Livran Estate, where, in the hospital established under the French Red Cross Society, several hundreds of wounded and sick soldiers have had a generous allowance of wine which, in the opinion of the medical attendants, bas assisted their rapid and complete recovery.

According to the Indian Trade Journal of September 15, Burmese Myrabolans as a Tanning Material.— a report on the Burmese myrabolans or "pangia" fruits as a tanning material, prepared by the chemical adviser to the Forest Research Institute, states that the Burmese myrabolans are different from the Indian Chebulic myrabolans in points of tannin and non-tannin contents tannin varies from 16 to 32 per cent; the general average and colour. In the air-dried Burmese material the may thus be taken to be 20 to 25 per cent, which is about half the tannin content of the Indian myrabolans. The non-tannin ranges from 25 to 34 per cent, and the general average may be taken to be 27-30 per cent, which is three times that of the Indian myrabolans. The colour is high. The maximum red and yellow recorded for the Indian myrabolans is 2.5 red and 7'4 yellow, while the Burmese myrabolans in general have 4'9 red and 18:35 yellow. The excess of non-tannin is a disadvantage, and all tanning materials having non-tannins in excess must be classed as somewhat inferior, though in practice they give fairly good results. To form some opinion as to the actual tanning properties of the Burmese myrabolans experiments were undertaken, which disclosed that leather made with this material alone is spongy and tough Burmese fruits can be used in the preparation of butts for like the leather produced by Indian myrabolans, that the making army boots and shoes, and also for making black uppers of inferior quality, and that they will be useful in conjunction with babul bark for making sole leather.Chemical Engineer and Manufacturer, xxiv., No. 5.
