Agauzy lace work of Sinewy Tissue is also interwoven throughthis tremulous Tissue to sustain it in its place and form,while a continuation of the same fibres, condensed into athin membrane, ensheaths the grey Tissue, its associatedwhite fibres, and its blood-tubes, completing a centre orGanglion. Several may have but one sheath, (see Fig. 14:.). 94 The extraordinary amount of blood supplied to this Tis-sue proves that its activity is exactly the reverse of thatof the white Nervous Tissue. Hence it is comparable tothe telegraphic battery. The blood which flows to it is of a bright red color,that which flows away is dark red. It has undergone achange, the Tissue must also have changed. It has takenfrom the blood choice materials, and has thrown into it itseffete substances, produced by its activity, which is depend-ent upon this change. These effete substances, harmless, even promoting healthwhen in small quantities, would become poisonous by accu-mulation, did not that faithful scavenger oxygen seize uponthem as fast as they appear in the blood of which it is apart, and burn or oxydize them into harmless compoundsfor the kidneys to eliminate from the blood. What they re-move from the blood is therefore sure evidence of the activ-i
