But the Ziifilqiiiinri‘cf Crillalline or Albuminous Liquor is of another Nature, as being the loft mum, and mild part of the Blood; and though it is a thin tranfparent Liquor, yet it will not evaporate like the potulent Matter, but refembleth the Albuminous Liquor of an Egg, which being expofed to the Fire in a Spoon, \‘Vlll become concreted into a whitifli Matter, not unlike the ‘coagulated White of i Aving given a Hillory ofthe Motion of Blood, Iwill now with your permiflion, {peak of its conflituent parts and Elements, as the Principles of Life, and of its various Difaffeélions, being the caufes of dif- ferent Fevers, as to many eminent Difeafes of the Heart. The Blood is a noble, if not the molt excellent Liquor of the whole Body, as all humours are preparatory to it, or part of its Liquor, or Reece» ments blended with it, or feparated from it; In this Liquor the early Rays of Life, the firil: operations of the Soul are difplayed : f0 that the Blood is a pa rt of as great Dignity as ufe, and Well worthy of a curious (earth, and fober confideration, as preliminary to our farther difcoutfe of the Brain, by reafon the albuminous part of the Blood is preparatory to the nervous Liquor, as being its Materizz Sula/tram, and is feparated from the Purple Juice in the Cortical Glands of the Brain.The Blood, the Theme ofour prefent Difcourfe, may admit a double Notion, as confidered in its natural, or dil‘afl‘ec‘ted Conflitutiong as relating to r . fi- .._._-,¢r ~ r ‘ «1-1" .3... in»; M its Salutary, it may notbe improper to pry into its Nature and Properties, which may in form e fort be comprized within three Heads, Firl't of the Origeir and Channels of it. tecondly, Of the conflituent and integral parts.
