Equations are developed for the rate of penetration of a substance into (or egress from) the zone included between two coaxial cylinders. In the most general case the penetrating substance is assumed to engage in diffusion, a chemical reaction of the first order and a zero-order reaction (e. g. metabolism). The rate of elimination of nitrogen from the tissues into the blood capillaries is considered as an example of diffusion alone, without any accompanying chemical reactions. Application of the simplified equations to this case strongly supports the view that the rate of elimination of nitrogen from the body when breathing oxygen is not conditioned by diffusion factors, but depends only on the volume of the various systems of the body and the rate of blood flow through them. The rate of passage of carbon monoxide from the blood to the myoglobin of red mammalian muscles is next considered as an example of diffusion accompanied by a first-order chemical reaction velocity. Calculations for resting and active muscles indicate that in the latter case certainly, and in the former case probably, the rate of up take of carbon monoxide by the red muscles should be fast enough to affect appreciably the measurement of blood volume by the carbon monoxide method. Millikan’s experiments on the rates of change of oxymyglobin concentration in the resting soleus muscle of the cat are used as an example of the most general case, in which diffusion and chemical reactions, both of first order and zero order, are all involved. The application of the equations of this paper to his data are shown to lead to reasonable conclusions as to the number of open blood capillaries in the resting soleus muscle. Similar equations, with examples, are also developed for the case of a cylinder suspended in an infinite medium and for a sphere suspended in an infinite medium.


Not the least important factors affecting the utilization of gaseous fuels are the remarkable effects of small quantities of catalytic substances, the presence of which may initiate or entirely change the nature of a combustion process. A proper understanding of these factors is therefore of great importance in the control of processes which are fundamental to many parts of applied chemistry. Such processes, however, are also intrinsically interesting for the insight they give into the ultimate mechanism of chemical reaction, and as a result of their study in the light of the theory of chain reactions, many empirical facts relating to combustion processes which previously were obscure now acquire a new significance. Of all these reactions the combustion of hydrogen and carbon monoxide stand in a unique position, for these substances more than any others occur as intermediaries in the burning of gaseous fuels; it is therefore of special interest to realize that the presence of traces of hydrogen may have a profound effect on the combustion of carbon monoxide, not only in lowering the temperature of ignition, but also in influencing the rate of propagation of the flame. This becomes of particular importance when it is remembered that carbon monoxide as used industrially nearly always contains traces of hydrogen.

Infrared chemiluminescence attributed to the first overtone of CO was observed when either C2H2 or was introduced into a stream of oxygen which had been passed through a microwave discharge. The addition of vibrationally cold CO to these systems was found to produce a vibrational population inversion in the chemically formed CO. CO first overtone emission was not observed when CH4 was introduced into a similar stream of oxygen unless the CH4 had been subjected to a microwave discharge. These observations are used to clarify the mechanisms governing the formation of CO in continuous wave air–helium–hydrocarbon electrical discharge lasers.
