The Rate of Alkaline Hydrolysis as a Function of the Constitution of the Alcohol. [Part] 2.
In a previous paper the authors present some of the results of their investigation on the alkaline hydrolysis of esters that showed the constitution of the alkyl radical in the ester has a noticeable influence on the rate of hydrolysis. The authors have extended their experiments beyond the propyl acetates to include aliphatic alkyl esters.

Survey of the Present Status of Isotope Separation Methods
The problem of the separation or enrichment of isotopes is as old as the knowledge of the existence of isotopes of stable elements. The article focuses on the mass-dependent property of atoms continuing to be investigated in laboratories to test its usefulness for new solutions to this problem.

On the Ordering Effect of a Sound Field onn Suspensions of Non-Spherical Particles
The movement and orientation in a standing sound field of non-spherical particles in which one dimension is small relative to the other two is treated. The time of migration into the loops (of the vibration) and the focusing duration (durability) of the same are given.

On the Possibility of an Acoustic Image in Analogy to the Optical: the Problem of Vision Through Opaque Media
A "sound-optics" is developed based upon the image-forming properties of sound waves. Examples are given of acoustic images of objects, and it is shown that among other things vision through opaque media is possible to achieve

The Raman Spectra and Structure of Perrhenium Acid and Perrhenate Ion
The Raman spectrum shows that sulphate, selenate and perchloride ions have a tetrahedral structure in solution. Tellurium, molybdenum and tungsten should be surrounded by six oxygen atoms and should therefore form a octahedral structure. The author investigates the Raman-spectra of several perrhenates and of perrhenium acid.
