The Weight and Composition of Eggs. Das Gewicht der Eier und ihrer Bestandteile während des Jahres und des Lebens bei Hennen. J. Podhradsky. Sbornik Ceskoslovenske Akademie Zemedeske, Vol. 11, 1936, p. 601.

In completion of former reports on this question it was ascertained that theresults partly confirmed the statements made by writers up to the present, namely, in so far as my experiments show.

1. 1. In the first year two big increases in weight take place, in spring and in autumn. These increases are followed by decreases which are generally underbroken by a smaller deviation, e.g., in April-June.

2. 2. In the first year these deviations occur both in albumen and shell and sometimes (contrary to what Philpott states) in the yolk.

3. 1. The following years show a similar cycle: the course of some of the curves is, however, less regular. The weight often begins at a higher level—mostly in older hens which have been laying for some years—but sinks progressively in the course of the year and is often underbroken by smaller deviations.

Examination of the Pituitary Membrane of the Throat in A avitamosis. Untersuchungen über die Histogenese der “Pusteln” der Schlundschleimhaut bei der Nährschädenerkrankung (A Avitaminose) der Hühner. L. Claussen. Deutsche Tierärtzliche Wochenschrift, Vol. 45, 1937, p. 161.

Description of the microscopic examination of the typical changes in the pituitary membrane of the throat in A avitaminosis. The festerings are caused by regressive changes of the pituitary membrane glands. The epithelium and the dividing walls of the glands are destroyed, the gland content becomes full of congealed exudate and tissue remains and this mass is extruded in a cheese-like lump. Inflamn1atory processes are not present.

Rapid Blood Test and Slow Serum Test in combating Pullorum Disease. La Siero-agglutinazione rapida e lenta nella diagnoso della pullorosi. Dr. F. Cattaneo. Rivista di Avicultura, 1934, p. 338.

1. 1. The sero-diagnostic tests represent the simplest and surest method of ascertaining infection with B. pullorum in hens.

2. 2. The rapid blood test, which makes it possible to isolate infected birds immediately, gives satisfactory results, but only when the treatment is applied by persons completely at home with the technique thereof.

3. 3. The slow test and the rapid test give similar results when applied with technical precision.

4. 4. Compared with the slow test the rapid test has undoubted advantages.

Calendar for Poultry Breeders, 1937. Kalender für Geflügelzüchter 1937. Editor: Fritz Pfenningstorff, Berlin, W.35.

This is the 39th edition of this calendar. During recent years great changes have occurred in Germany, also in the field of poultry breeding, and various problems have been studied with great care at different institutes, and this calendar gives important information of the results of the research work carried out.
