a fact which was known before Mendeleèff's time purely as a result of experimental work on these elements. The movement of oil drops and the interchange of substance in osmosis are certainly quicksand foundations upon which to build inter-relationship theories of the animate and the inanimate. This superficial connection fails to stand the test of adaptation and coordination—to name two characteristic features of the vital substance. Indeed, our knowledge is so remarkably extensive that we can not as yet state the simplest vital manifestation in terms of science.
But this does not make a discussion of this kind any the less valuable. The impetus to research that it gives is productive of the highest good to mankind, for if the results do not solve the problem, the scope of the problem becomes so much clearer. The whole, which is made up of many coordinated components, eludes the grasp, but the individual components are gradually revealing many of their secrets to the untiring scientific explorer. With the physiologist ever attentive in his study of the human mechanism, with the chemist carefully analyzing and synthesising the more complex forms of matter so intimately associated with life's activity, with the scientific philosopher investigating the laws common both to animate and inanimate substance, who would venture to foretell the outcome?
The present situation may be summed up in some such way as this:
1. (a) Chemistry and physics may possibly contain all the necessary factors, our ignorance being due to our inadequate knowledge of these sciences, especially chemistry; or (b) There may be an outside factor.
2. Whilst no definite theories as to the origin of life can as yet be advanced, it is not unreasonable to suppose that in process of time, with consequent development, a better insight into (a), or an idea of (b) will be obtained. Fancy may well picture even the acquirement of new faculties, which will bring within range many of nature's present secrets, unattainable by present methods.
3. At present we know of no better way of pursuing our search than through the sciences. But here we are only safe when we apply them to the things we can grasp. The application of scientific methods to the spirit world (the methods of Crookes, Lodge and others) have thus far been barren of result. Science, as we understand it, rules in the world of matter, but it does not beyond. Whether this "matter" is but a manifestation of the "spirit," whether there is any relationship between them, or whether, indeed, they spring from the same source, time may, and time may not tell. Our duty is to plod the weary way, irrespective of where it leads to, or what the outcome of it may be. Patience, diligence and truth are our guiding stars.
