enzyme activity, fewer bacteria, lower yeast count, and greater uniformity in the alcohol yield were observed in t h e treated mashes. Among papers on barley and malting, R. F . Bawden, of Ilahr Malting Co., re ported t h a t the use of hormonelike growth substances are not effective in overcoming dormancy in barley as readily as hydrogen peroxide. Indole-, phemoxy, naphthoxy, and triiodobenzoyl derivatives of acetic acid were employed. T h e opinion t h a t the biological oxygen demand test does not give t h e whole pic ture in judging the effect of brewery wastes on stream pollution wis voiced by H. C . Mason, of J. E. Siebel Sons' Co., who pointed out t h a t the solids content of distillery wastes is higher than t h a t of brewery wastes with a c o m p a r a b l e b.o.d. The average brewery 5 - d a y b.o.d. w a s placed at about 6X)0 p.p.m., and in view of the fact t h a t brewery wastes a r e greatly diluted with w a t e r , concluded Mr. Mason, t h e y show favorable com parison with o t h e r industrial wastes. Analytical papers stressed t h e efforts
of brewery chemists to maintain uni formity of product. They included a discussion of the interrelations of nitro gen fractions in worts and beers, a rapid fluorometric method for t h e determina tion of riboflavin in yeasts, and two papers on the determination of iron in beer. A comparison of color judging by visual and photometric methods was given by Irwin Stone, of Wallerstein Laboratories, who concluded t h a t the Lovibond scale is n o t entirely s^isfactory and suggested a new standard based on a color unit with an optical density of 0.088 at a wave length of 440 ήΐμ.

Corrosion Engineers 9 Convention a n d Exhibition A STAFF
REPORT
V>IORROSION and its causes and preven tions were the subjects of enthusiastic and businesslike attack: b y t h e National Association of Corrosion Engineers in its annual convention and exhibition held in K a n s a s City, May 7, 8, and 9. Attract ing engineers from all sections of t h e country and a variety of industries, t h e meeting recorded an a t t e n d a n c e of well over 500. M u c h emphasis was placed on the range of fields in which corrosion study is valuable and among more t h a n 35 papers of technical nature t h e variety of industrial applications was impressive. T h e group m a d e it dear t h a t its organiza tion, which w a s once' considered pre dominantly a petroleum man's associa tion, h a s now extended itself t o attract a n y technologist concerned with corro sion problems. Considerable discussion was devoted t o the cooperation of the N A C E with other groups in related fields a n d serious interest in t h e fostering a n d planning of research was evident. I t was announced t h a t t n e board of directors h a d voted a p p r o v a l of a plan whereby t h e MACE hopes t o edit and publish, with thie assistance of t h e Ameri can Coordinating Committee on Corro sion, abstracts of ail worthy articles on corrosion from the U n i t e d States and foreign countries. The entire final after noon of t h e convention was devoted to reports on w o r k pertaining t o corrosion by other technical societies, during which
1380
t h e work of 14 organizations, in cluding the
AMERICAN CHEMICAL
SOCIETY, was discussed.
