INTERNATIONAL REVIEW OF POULTRY SCIENCE OFFICIAL ORGAN OF THE WORLD'S POULTRY SCIENCE ASSOCIATION EDITOR: DR. B.J. CTEHENNEPE ROTTERDAM (Holland) Published by: Frifz PfenningstorfF, Berlin W 57 FOREWORD to the First Number of the Eîgth Volume. I herewith have the honour to offer you Vol. 8, No. 1/2 of the Inter- national Review. In the seven Volumes published since 1928 summaries have been given of numerous publications dealing with poultry. In spite of the crisis there is no decrease in the number of publications regarding poultry, but I am sorry to say, owing to lack of finances, I have not recently been able to review and publish articles as quickly as I should like to, after their appearance. Mean while large quantities of material have been published in the years referred to, of which the following table will give you an idea: nggs ana Breeding Nutrition Diseases Table Poultry General Total Vol. I 1928 31 40 123 67 261 Vol. II 1929 49 77 164 80 370 Vol. ill 1930 74 89 235 45 136 579 Vol. IV 1931 89 122 317 56 119 703 VoLV 1932 26 54 364 39 58 541 Vol. VI 1933 130 157 363 65 182 895 Vol. VII 1934 149 161 114 68 147 639 548 700 1680 271 789 3988 As you will see from the list published in each number, the Review Is already being exchanged for about 100 periodicals dealing with poultry. From other sources about 50 scientific periodicals are placed at my dis- posal. I am therefore not afraid to state that the Review gives fairly faithful reflection of all world literature on the subject of poultry. I am in regular receipt of publications both from Scientific Insti- tutions and Laying Trials but the work would be still more complete if readers would give greater support, in the form of sending literature they publish themselves or of which they hear. The International Review fills the periods between the World's Con- gresses, and during these periods tries to keep up and to strengthen the contact between scientific investigators. The cost of publishing the Review is heavy and it is therefore of great importance that every reader should do his utmost to win new members for the World's Poultry Science Association. The World's Congress to be held in Berlin in August 1936 is rapidly approaching. A large staff of experts in Germany are working very hard on the preparations and I hope to be able to keep readers posted regarding the progress made. I hope that, with the aid of all those interested, we shall be able in the coming Volume to improve oiu: work and so come nearer to the object of the Review, namely: "The centralization of scientific data and the distribution thereof over the whole world." 2* THE WORLD'S POULTRY SCIENCE ASSOCIATION and the PREPARATION FOR THE VP^WORLD^S POULTRY CONGRESS AT BERLIN, 3P* July to 9*^ August, 1936. After various conferences with the German Congress Comîttee, of which the president of the World's Poultry Science Association, ProL A. Ghigi, is vice-president and the undersigned a member, it was decided, after consulting the president, to call a meeting of the European Members of Council in Berlin on the occasion of the ''Grüne Woche" (Green Week) in that city* The following circular was then sent to the members of Council. Meetings of the Council of the World's Poultry Science Association, Berlin* Sunday, 27ih January 10 a. m. A.

Dinner in Restaurant Kroll offered by the German Con- gress'Committee. The Minister of Agriculture Exc, Walther Darré will preside at table. As these meetings will be of great importance I hope many members of Council will be present. We took these dates as one of the largest and most famous agri- culture shows of the Continent will be held during that time, the so called "Grüne Woche" (Green Week). Every year this exhibition attracts nearly 300,000 visitors from several countries to Berlin. During this show the international horse-riding competitions (Reit- und Fahrtumier) will be held, where the best teams from many countries meet each other. The Congress-Committee offers to all members of Council a free entrance-ticket during the days of the show. On Monday morning there will be a meeting of the Executive- Congress-Committee together with Professor Ghigi and Dr. te Hennepe, who were elected as members of this committee. For the meeting in the afternoon 15 p. m. at the Ministry of Agri- culture the Executive-Committee of the Congress asked me to invite all Members of Council of the W. P. S. A. All members of Council can stay at the Hotel Kaiserhof. This hotel is situated in the centre of Berlin quite near the Ministries and the Congress Building. The prices of the rooms are 11 Mark with bath, 8 Mark without bath. Travelling from foreign countries into Germany now is cheap while foreigners can buy so called "Travelling-Marks", "Reise-Marken" at a price of about one shilling English. We shall now have the opportunity to discuss various questions with the Executive Congress-Committee, to see the Exhibition-grounds and the beautiful Congress-rooms in the Prussian House of Parliament (Preußenhaus). Enclosed you will find in separate cover a prospectus of the "Grüne Woche". I hope to be able to forward you within few days a draft of the preliminary Program of the Congress, so that we can discuss this in our meeting in Berlin. I shall be pleased to know as soon as possible, if you will attend these meetings, so that I can book rooms for you at the hotel and shall also be pleased to give you all further information about travelling to Berlin which you may desire. Faithfully Yours, B. J. C. te Hennepe. Official invitations for the Congress are sent off by the German Government by means of their ambassadors in your countries by the 10th of December. Please write to me by return of post, if your govern- ment received the invitation. Sunday, 27. January. A* B.
