In a recent number is a criticism under the above title by Sir R. T. Glazebrook, of some figures given by me in a paper with the same title. I am accused of not giving Holborn and Henning's own figures, because I State that part of my curve is filled in from the researches of Swann, and of Holborn and Henning. As Swann and Holborn and Henning are not in agreement, it seems evident that one set figures cannot be used without some adjustment to the other set. These discrepancies were dealt with by the British Association Committee (of which Sir R. T. Glazebrook later became a member) in their 1908 Report, and the figures I give are in fairly close agreement with theirs for the low temperatures. I State in my paper (p. 492) that I find Holborn and Henning about 7½ percent. too low at 800°C. for air and steam, and I assume that the same error applies to the carbon dioxide. (Prof. Callendar suggests their error may be as much as 10 per cent. at 1400°C.) I have, therefore, distributed this error over the range for which I have used Holborn and Henning's figures. On this account it may be anticipated "that the figures at the higher temperatures are higher than the corresponding figures due to Holborn." I believe it is usual, when quoting the results of other workers, to attach their names to the figures quoted; this I have not done.

The reaction between strontium carbonate and iron(III) oxide has been studied in a system open to the atmosphere and in a vacuum. The extent of reaction was calculated from the analysis of the solid products by X-ray diffraction and, in the case of the experiments in vacuum, from the amount of carbon dioxide evolved from the system also. ��� In vacuum, the monoferrite SrFe2O4 results from the direct reaction of strontium carbonate and iron(III) oxide at comparatively low temperatures, while the hexaferrite SrFe12O19 is formed by the reaction of Sr2Fe2O4 with iron(III) oxide at higher temperatures. The formation of the ferrite Sr2Fe2O5 depends upon the prevailing atmosphere, since this compound was present only as an intermediate phase when the experiments were carried out in air and not in vacuum. Only three compounds of strontium, iron, and oxygen were found, namely the ferrites SrFe2O4, Sr2Fe2O5, and SrFe12O19. ��� The observataions appear to be explicable in terms of Tammann temperatures.

Scientific Attention

The possibility of alleviation of methane and carbon dioxide levels in the atmosphere are of major global interest. One of the alternatives that attracts much scientific attention is their chemical utilization, especially because both of these gases are components of the biogas. Thus, the rapid and extensive shale gas development makes them abundant raw materials. The development of an effective catalytic process that could be scaled-up for industrial purposes remains a great challenge for catalysis. As well, understanding of the mechanisms of molecular activation and the reaction pathways over active centers on heterogeneous catalysts needs to be advanced. It has been shown that biogas is a very interesting source of renewable energy. Because of its elevated methane content, biogas has excellent potential, as reflected in its year-over-year rise in production. This is because its manufacturing promotes the use of organic waste, prevents uncontrolled dumping and minimizes atmospheric methane and carbon dioxide emissions. Moreover, its use as an energy source is in some cases an alternative to fossil fuels and can help to minimize energy dependence. Another aspect of interest is that it can be used in situ, allowing agro-livestock farms or small industrial plants to achieve energy self-sufficiency.
