    Notes: This paper suggests that empirical educational research has not, on the whole, been treated well by philosophers of education. A variety of criticisms have been offered, ranging from triviality, conceptual confusion and the impossibility of empirically studying normative processes. Furthermore, many of those who criticise, or dismiss, empirical research do so without subjecting any specific examples to careful scholarly scrutiny. It is suggested that both philosophy of education, and the empirical research enterprise, stand to profit if philosophers pay more attention to real cases—and this attention is especially important at present, when research funding is being based on spurious scientistic criteria such as the use of ‘gold standard’ randomised experimental research designs.

    Notes: [Auszug] SANGER1 has described the use of 1: 2: 4-fluoro-dinitrobenzene to identify the free amino-groups of several proteins, employing the separation of the N-dinitrophenyl amino-acids on columns of silica gel. We have had only limited success applying this method, owing to variations ...

    Notes: [Auszug] IT has been shown1 that, by the action of chymotrypsin, insulin is broken down into a number of peptide fragments of comparatively small molecular weight, and a more massive residue. The higher molecular weight material can be precipitated by means of trichloro-acetic acid. ...

    Notes: [Auszug] ON account of its stability and well-defined crystalline character, insulin is a favourable point at the present time to attack protein structure. Its composition is probably better known than that of any other protein. The stoichiometrical molecular weight, that is, the least Weight into which all ...

    Notes: [Auszug] WITH increasing use of chromatographic columns, the need has arisen for automatic fraction-cutting apparatus. Stein and Stanford Moore1 have devised such an apparatus in which the fraction is measured photo-electrically and the battery of receivers then moved on by an electric ...
