172 STUDIES IN ELECTRO-PHYSIOLOGY: 



From this it would appear that the two arborisations as 

 shown in the enlarged sketch of D (Fig. 91) may actually 

 touch or embrace each other, so that no additional resistance 

 may be offered by intervening connective tissue, but even 

 in such case there .would be two thicknesses of dielectric 

 (d, d) to one of conductor (c) in the path of the impulse, 

 and the result must be delay during the accumulation of 

 tension at the arborisation nearest the cell, the plates being 

 further apart. 



As the cell is in the superior cervical region two things 

 follow, logically: i.e. (I) the impulse from it is efferent, 

 and (2) the tension in the dendron is comparatively high. 

 We know also that electricity concentrates upon points or 

 projections, and the arborisations appear to be constructed 

 in accordance with this law. 



When we are able to examine the structure of the 

 brain, I think the evidence in support of the human organism 

 being neuro- electrically controlled with consequent 

 chemical action will be even more convincing than that 

 I have already adduced. 



One thing stands out prominently and it cannot be 

 given too great prominence this vital action, neuro- 

 electrical or chemical, or both, cannot go on unimpaired if 

 the natural insulation resistance, in any part of the body, is 

 broken down or interfered with. 



CONNECTION OF MUSCLES AND BONES, ETC. 



If, in addition to a consideration of the different 

 behaviour of muscular tissue owing to differences of tension* 

 quantity, and resistance, we unite a brief survey of their 

 connection with bones, we may obtain a still better grasp of 

 the subject. As a considerable number of muscle-fibres 

 constitute the trunk of the muscle, strong slender threads 

 of the nature of connective tissue unite into cords which
