A KNOWLEDGE of the behaviour of formaldehyde and acetaldehyde at high temperaturw is essential to the correct interpretation of the reactions concerned in hydrocarbon flames, and we have accordingly made a number of experiments at temperatures between 400° and 1150", the results of which are summarised in this paper. The general arrangement of the apparatus employed in most of the experiments is shown in the accompanying diagram. The vaponr of Hydroten the aldehyde under investigation was

The body of A terminated in long narrow ends (2 mm. bore) which projected for some distance beyond the heated zone. The cold ends were joined by stout pressure tubing to the glass stopcocks, a and b, through which connection could be made with the aldehyde vaporiser or with the manometer, M, and thence, through the stopcock, c, with an auttoniatic Sprengel pump, as circumstances required. A small glass worm (not shown in the diagram) containing about
