Blood-Vessels.  –on the next lap we have a graphic illustration of the internal arrangements of the blood-vessels of the lungs and bronchial tubes.  The pulmonary artery, arising from the right ventricle of the heart, conveys the venous blood to the lungs.  It penetrates the lungs and divides and subdivides into branches, which accompanied the bronchial tubes and terminate in a dense capillary net-work upon the walls of their cells, where the blood undergoes that magical change, giving up its poisonous qualities and becoming revivified and healthful.

Note the use of the word ‘net-work’, obviously an early predecessor to the very common word network.  I found this little nugget of gold to be very interesting as networks are so synonymous in today’s world and speech, and found it very amusing to find an example of the early use of the word before it had truly come together into its modern-day form, which even today is now abbreviated to a more common usage of “net,”  I guess we take the “work” in network for granted these days.
