[[left margin]] Difference between Amphibious & land animals. 

How the circulation in the foetus is carried on. [[/left margin]]

[[body]]
"The essential difference (as to the general structure of the heart) between amphibious and meer land animals, or such as never go into the water, is that the [[underline]] foramen ovale [[/underline]] remains always open; thro' this is a communication, and the circulation is kept up, tho' the animal does not respire while under water." Monthly Review for Dec. [[superscript]] r [[/superscript]] 1767. On a N. [[superscript]] o [[/superscript]] of the Philosop. Trans. for 1766. 

[[new paragraph]]
   "The blood brought by the vena cava into the right auricle of the heart takes three different courses in the foetus. One part goes directly from the right auricle through the foramen ovale into the vena pulmonalis; and thence into the left auricle, without passing through the lungs. The other part goes from the right auricle into the right ventricle of the heart, and thence into the pulmonary [[strikethrough]] artery [[/strikethrough]] artery: this again is divided into two courses; one part proceeds from the pulmonary artery into the aorta descendens, through the canalis arteriosus; and what remains, is sent through the lungs by the ramifications of the pulmonary artery.
--Hence it is evident, that in the foetus, but a small proportion of the blood passes through the lungs themselves; which are as yet collapsed and in a great degree impervious. After birth, however, in meer land animals, respiration takes place, the passage through the lungs becomes free, and the foramen ovale, with the canalis arteriosus, are closed. Hence the whole mass of blood must necessarily after this pass through the lungs: and consequently whenever respiration ceases, and this passage through the lungs [[insertion]] is [[/insertion]] obstructed, wheter from immersion in water, or from any other cause, the circulation is suppressed, and death must immediately ensue."

[[new body paragraph]] "The prince de San Severo is famous at [[underline]]Naples [[/underline]] for his many discoveries in chemistry. He has learned to give white marble a fixed tint of any colour; a tint, which penetrates the whole mass, how thick soever. What is still more surprizing, is a cube of white marble two foot square, on one side of which is painted a figure of the virgin, which is found on all the leaves that are saved from the block. [[underline]] This prince has also discovered the secret of the inextinguishable lamps of the ancients." [[/underline]]

[[new paragraph]] "The island of Anticosti is situated at the entrance of the river St. Lawrence, between the parallels of 49°..4’ and 49°..53’..15"N. latitude and the meridians of 61°..58' and 64°..35' West longitude from London determined by ten observations on the eclipses of Jupiter's first satellite. Its circumference is 282 statute miles, its length 129 miles, and its breadth from 32 to 12 miles. This island contains 1699840 acres of very indifferent land." ---- [[strikethrough]] p.66 [[/strikethrough]] ---- p.65  "The winter that we spent on this island was very
