    Notes: It is typical of the present time, that two practically unknown chemists, one from a veterinary college and the other from an agricultural institute, pass judgement on the loftiest problems of Chemistry, those which will probably never be solved, particularly the question of the position of atoms in space, and they undertake such a paradigm with an impudence and assurance that absolutely astonish the true scientist H. Kolbe [1] New paradigms and new truths in science are not usually adopted because opponents are eventually convinced of their persuasive character, but, more often, because opponents gradually die; the new paradigms are readily adopted by the new generation of students as the laws of nature, just as the dead opponents accepted the old paradigm M. Planck [2]

    Notes: The low resolution mass spectra of several di-, tri-and tetra-methylated cyclobutanones were determined at high and low ionizing voltages. The spectra are discussed in terms of the competition between loss of CO or loss of a ketene from the molecular ion of the cyclobutanone. The mass spectral results are correlated with the known photochemical behavior of the cyclobutanones and possible mechanistic implications are discussed.
