some bubbles on the water when their breath went out, as in breathing animals when they die in the water. It is true that lunged fishes, such as Dolphins, Whales, Seals, and Frogges, make bubbles, because they breath, which will not prove that all fishes do so. And yet there be other causes of bubbling be∣sides expiration: for rains, tempests, vapours, or any agitation of the water will cause bubbling. Object. 8. The Moon gives increment to shell-fishes, therefore their spirits also do increase. Answ. It's true, if they speak of the animall and vitall spirits; but what is this to breathing, the subject whereof is the air, and not those innate spirits: and if increment of substance doth suppose respiration, then trees must breath as they grow in bignesse. And although the Moon causeth humid bodies to swell, yet she doth not make the air by which we breath, being a part of the Universe. Object. 9. Fishes doe smell and hear, therefore they breath, because air is the matter of all three. Answ. Air indeed may be called the matter of breath∣ing, but not of hearing and smelling; it is not the air we smell or hear, but we smell the odors, and hear the sounds in the air, which is therefore properly called by Philosophers, the Medium, not the mat••er of hearing and smelling. And as the air is to us, so the water is to fishes the medium of hearing and smelling: And if it be the matter of breathing to fishes, then it is not air but water which they breath; whereas indeed wa∣ter cannot be the subject or matter of breathing, nor can they breath at all which want the organs of breath. Object. 10. No animall can live without respiration, therefore fishes breath. Answ. The antecedent is denied; for many animals live with∣out respiration, onely by transpiration, such are insects, so doth the child in the matrix, so do women in their histericall passi∣ons, these breath not, yet they live. Object. 11. Pliny tells us that fishes do sleep, therefore they breath. Answ. Breathing hath no relation to sleep, it is neither the effect, nor cause, nor quality, nor part, nor property, nor consequent of sleep: for some animals sleep, which breath not all that time, as Dormice in Winter, the child in the mothers womb breathes not, as ha∣ving in the matrix or membran within which he lieth, no air at all, but a watrish humor, which if he should suck in by the lungs, he would be presently suffocated; yet at that time the chid sleepeth. There is no community at all in the subject or organ of sleep and respiration, nor in their natures, the one being a rest or cessation, the other a motion; the one consist∣ing in the senses within the head, the other in the lungs, breast,
