generated by the Animal Parents of the fame Spirits. The fame he confirms 
as to Plants, by an Experiment of Malpxgim, who covered Earth taken from 
a deep place with Silk many times doubled, which though it admitted the 
Air and Water, yet produced not any Plant \ and concludes, that a fponta- 
neons Generation of Animals and Plants will be found, upon due examination) 
to be nothing lefs than a Creation of them. He enforces this Opinion by 
the Suffrages of the moft Experience in this matter, as Shammer lem, Mai- 
pigbi-, Lifter, &c. For this he brings feveral Arguments, and anfwers the molj 
material Objections, and as for the raining of Frogs and other lnftfis, he be- 
lieves it with the fame Faith, as that Spanijh Gennets are begotten by the 
Winds, fince each Story is attefted, as he fays, by good Authors, and he 
that can fwallow this, hath, he thinks, made a fair ftep towards believing it 
may rain Cilves too, fince it is reported that one fdl out of the Clouds 
in Avicenna's time. Here he takes notice of the long Venereal Embrace of the 
Frogs, for at lead a whole month indefmently. As to Infefts produced in 
Animal Bodies, he concludes them not fpontaneows, from their exact agree- 
ment, and perpetual fimilitude, in the (nape and figure of their Bodies, and 
concludes, that the Eggs which produce them are taken in with the Food of 
the Animal in which they are found. 
In the next place he gives feveral MifciUantous Obfcrvations of the Structure, 
Actions, and Ufes of fome Parts of Animals, omitted in the precedent Dif- 
courfes as, That God effects the fame thing by different means inilanccd in 
the Varieties of Digeftions in the Stomachs of feveral Animals, and the like. 
By the way he fays, that Swine wallow in the Mire, and Poultry bask them' 
felves in the Duft, not to cool themfelves, but to deftroy and choak the Lice 
and other importunate Infects. Our Author has other Obfervables touch- 
ing Rejpkation, the Foramen Ovale in amphibious Animal;, the Epiglottis, 
which part the Elephant has not, neither needs it, there being no Commu- 
nication betwixt his Luags and Oefophagus Some Jnflanccs of the Sagacitv 
of the tortoifi i of theirs and the AmadiHo\ Armour, which latter contracts 
it felf into a rouud BaP, by the means of a notable Mufcle on each fide, cor- 
fifling of many Fibres, decuflating each other like the letter X. Next he 
hints at the U(es of the Fat a<id the nictating Membrane in the E}cs of Beaftsy 
and Birds, tranferibing a large account of this part out of the Parijian Ana- 
tomy of Animals. Next of the fudden growth of Fltfh-Flyes, which he finds 
neceflary for their production-, with fome Particularities tonching other 
Animals. He conjectures, that Car til ag'mous Fifh raife and fink th-mfelves 
to any Depth, by the Water which they take in and let out again at pleafure, 
by the help of Mufeles for that purpofe, at two holts in the lower part of their 
Belly. 
Speaking of Vlants, he fays, it is the descending Juice which is taken in 
by the Leaves that nourilhes both the Fruit and plant. There arc feveral 
other particulars worth the Reader's perufal, and after all he concludes with 
many practical Inferences and Deductions from the whole. 
The whole Treatife, though it be of a Philofophical Nature, feems to be of 
great ufe for fuch as make popular Difcourfes 5 and as it is not far above the 
Capacity of the Meaner, fo there are feveral Paflages that will at leaft give 
hints and aftiflance to the greateft Theologues.
