Dr Rabagliati and Professor Atwater are, I believe, both right, but the former does not always explain himself clearly to the lay mind. The life-force or animal magnetism is the real source of bodily energy, and it manifests itself only when it has something that resists or regulates its flow.

It does this just as certain forms of wire, or other materials, which possess indifferent conducting power, resist the flow of electricity through them.

Electricity cannot manifest as light in the usual electric lights used in our houses, as heat in the electric culinary appliances or stoves, or even as power in the motors which run our trams and trains, unless it be given the requisite apparatus to bring about the manifestation required.

In exactly the same way life cannot manifest itself as consciousness, with its flow of thoughts, emotions and bodily activities, without the food which is daily supplied to the body.

It consequently depends considerably upon how we select our daily rations as to how this vital force will manifest within us.
