Influence of money upon the social organization

The extraordinary importance that has been attached to money throughout the ages may be appreciated when such modern writers as Alexander Delmar suggest that the history of money is the history of civilization. While this view is not accepted by most writers of the subject, all are nevertheless agreed that money plays a role of enormous importance in the affairs of men. Even in the classics are found quotations which stress this importance of the pecuniary unit upon ethical as well as economic standards.

Preparation and attempted resolution of benzoyl-malic acid

The final object of this research was to prepare m-nitrobenzoyl malic acid and to separate it, if possible, into the four stereoisomers predicted by the Huggins' theory of the benzene ring. Inasmuch as the quantity of m-nitro- benzoyl chloride available was limited it was thought better to first prepare i-benzoyl malic acid and then attempt to resolve it. The resolution of m-nitrobenzoyl malic acid could probably be accomplished by a similar method.

An investigation of various types of arc welded joints

In the last few years there has been much discussion as to the relative merits or arc welded joints as compared to riveted joints. There is an old precedent which must be removed before arc welding will come into its own. The purpose of this paper is to help establish confidence in this process of fabrication with special regard to strength and reliability.

A short thesis on arc-welding

During the past few years the attention of architects, engineers and others encased in or connected with the building industry has been attracted to the possibilities of the application of welding processes to the joining of structural members. As oxy-acetylene welding was developed before electric arc welding became perfected it was only natural that the gas torch should be first considered. It developed however on examination of the two processes that while acetylene welding gave better results in most cases it was only in the hands of experts that it could consistently outscore the arc as a welding medium. Arc-welding has the advantage over the acetylene process, where each individual operator must use his own judgement as to the proper flame, in that a squad of arc-welders can work under the direction of a single expert supervisor who accepts the responsibility of fixing the current value and of determining the proper size of welding rod to be used on any given type of work.

Industrial democracy

Since the beginning of human relations, some of the more ambitious and more capable members of society have by various means found and practiced methods of exploiting the efforts of their fellowmen to their own personal interest. These individuals have been naturally gifted at organization and control and have been able to dominate their slower, less mentally active associates. It is a cumulative process, once having been started the act of further subjugation becoming easier and easier as the clever person gets more and more control over the other.

The equivalent conductance of solutions of picric acid

Picric acid possesses the property, which is rare among strong electrolytes, of having a convenient distribution ratio between water and certain organic solvents such as benzene, chloroform, etc. Because of this property, picric acid offers peculiar advantages for studying the well known deviations of strong electrolytes from the law of mass action, for; by means of distribution experiments, the activities of picric acid in various aqueous solutions may be compared.

In order to interpret the results of such distribution experiments, it is necessary to know the degree of ionization of picric acid in aqueous solutions.

At least three series of determinations of the equivalent conductance of picric acid have been published, but the results are not concordant; and therefore, the degree of ionization cannot be calculated with any degree of certainty.

The object of the present investigation was to redetermine the conductance of picric acid solutions in order to obtain satisfactory data from which the degrees of ionization of its solutions might be calculated.
