Some Noifcs (whereof we fpake in the 112. Experiment ) helpc ] 
Sleepe-, As the Blowing of the wind) the Trickling of water , Humming of l 
Bees, Soft Singing Reading, &c. The Caufe is, for that they moue in the ' 
Spirits a gentle Jttentibn-, And whatfoeuer moneth Attention, without 
too much Labour, ftilleth the Natural! and difeurfiue Motion of the 
Spirits . 
slet-pe nourifbeth, or at leaft preferueth Bodies, a long time,, without 
other Nourishment. Beajis that fleepe in winter, (as it is nored oi'wilde 
Beares,)d uring their Sleep, wax very Fat,though they Ear, nothing.#**/ 
haue beene found in OLiens, and other Hollow Clofe Places, Matted 
one vpon another; And therefore it is likely that they -sleeps in the Win¬ 
ter time, and eat Nothing, Quyrc, whether Bees doc not sleep all Win¬ 
ter, and fpare their Honey l Butterflies , and other plies, doe not oncly 
sleepe , but lie as Dead all winter , And yet with a little Heat ot'Smne', or 
Fire, reuiiie againe. A Dormoufe, both winter and Summery will Sleepe 
fome dayes together, and eat Nothing. 
To reft ore Teeth in Age y were Magnate NatUr#. It may bee 
thought of. But howfoeuer the Nature of rh cTeetb deferueth 
co be enquired of, as well as the other Parts of Lining Creatures 
Bodies. 
There be Fiue parts in the Bodies Lining Creatures yhaz are of Hard 
Sukflance jThe Skull-, The Teeth, The Bones-, The Hornes ; aifcUbe Naiks. 
Thegreateft Quantity of Hard Subflance Continued, is towards the 
Head. For there is the Skull of one Entire Bone ; There are t he Teeth ; 
T here are th eMaxtllarie Bones-,Thetei$ the Hard Bone,that is the Jnjl fo¬ 
ment of Hearing • And thence ilTue the Hornes : So that the Building of 
Lining Creatures B 0 dies,is like theBuilding of a T imber-Houfe,' where the 
walls and other Parts haue Columnes and Bedtnes ; But the Roofe is, in 
the betterSort of Houfes,a\\ Tile,otLead,ot Stone. As for£zV^x,theyhaue 
Three other HardSubflances proper to themjThe Bill, which is of like 
Matter with the Teeth, Vor no Birds haue Teeth ; The shell of the Egge; 
And their Quils : For as for their Spurn, it is but a Naile. Bueno Li¬ 
lting Creatures, that hau e shels very hard 5 (As Oyflers,Cockles, Muffles’, 
Scallops,Crabs,Lobflers,Cra-Fijh, Shrimps, and especially the Tortoife,) 
haue Boneswi thin them, but onely little Griftles. 
Bones, after full Growth,continue at a Stay: And fo doth the skull: 
Hornes, in fome Creatures , are caft and renued:T ceth ftand at a Stay,ex- 
jsept their Wcaring-.As for Nailes, they grow continually: And and 
Beakes will ouer-grow,and fometimes be caft •, as in Eagles, and Parrots. 
Mod of the Hard Subflances fUe to the Extremes of the Body*, As skulf 
Hornes, Teeth,Nailes, and Beakes : Only the Bones ate more Inward, and 
clad with Flefh. As for the Entrailes, they are all without Bones ; Sane 
that a Bone is (fometimes) found in the Heart of a' stag ; And it may be 
in fome other Creature.
