skin and muscle structures respectively, as nutritive plasma 

 in turn. 



These statements consequently require a modification 

 of our beliefs with respect to the power of circulation of 

 nerve and other fibres and their capability of conveying 

 the elements of nutrition as well as energy. 



The principle of universal circulation is intimately 

 associated with the processes of secretion and excretion 

 and the functions and structures of glands, consequently 

 these subjects are largely dealt with in detail preparatory 

 to taking up the pathological and clinical bearings of the 

 subject. 



The glands referred to particularly are the pituitary and 

 coccygeal in their connection with the subject of cerebro- 

 spinal lymph excretion, and the related pineal, lachrymal, 

 nasal and salivary glands, also the parotid glands and 

 carotids. 



Moreover, this last-mentioned aspect of the subject calls 

 for the statement of the fact that a large number of 

 diseased conditions are found to owe their origin to inter- 

 ference with the principle of local and universal circulation. 

 It is almost unnecessary to say that the data warranting 

 these statements have been collected from all available 

 sources and that in the course of collection thousands of 

 individual and collected facts have been utilised, leaving 

 behind, unutilised, uncountable stores for similar purposes 

 which are now, to a great extent, lying idle and in danger 

 of being buried amid the daily and yearly accumulations 

 being added to them in all civilised countries. Indeed, it 

 seems to us that the greatest need at the present time is 

 the assimilation and assortment of this vast and rapidly 

 increasing body of loosely coherent knowledge, and the 

 deduction of the laws underlying and interpenetrating its 

 vast bulk, ere it becomes unattainable from mere dimen- 

 sions and variety. 



Here we would enter a plea for the observance of 

 simplicity and continuity in the syntactic advancement of 

 science in order that every analytic fact may be utilised 

 at once as it becomes added to the sum of knowledge, 

 to the end that special knowledge should be at all times 

 available for general use.
