IN the _fourth Month, Astrologers_ will have the _Planet_ SOL to reign over the INFANT; whose _calid Quality_ gives it entire LIFE, fully perfecting the _Members_, excavating the _Bones_, and amplifying the _Pores_ and _Passages_ of the Body. AS, in the _Fifth_, VENUS presides over the INFANT; who, by her _Frigidity_ and _Humidity_, mitigates the _Heat_ and _Siccity_ impressed on it by the _superiour Planets_, absolutely perfecting the _Lineaments_ of the _external Members_. According to which Principles, she, in a word, forms the _Privities_ of both _Sexes_; and adds Beauty and Ornament to the _Nose_, _Mouth_, _Hands_, _Fingers_, and all the rest of the _visible Parts_. AS also, in the _sixth Month_, MERCURY takes his Turn to assist the INFANT, which puts the last finishing Hand to the _Work_; perfecting the _Organs_ of the _Voice_, enlarging the _Eyes_, _Eye-lids_, _Brows_, and _Nails_; promoting and confirming the _Instruments_ of _Motion_; and at last, absolving and compleating whatever the _others_ have commenced. I shall only farther _hypothetically_ observe, that, if the INFANT was perfectly _form’d_ about the 35th _Day_, it was _animated_ about the 70th, and consequently will be _born_ about the 210th _Day_, the last of the 7th _Month_. IF the _Formation_ was perfected about the 40th _Day_, the _Animation_ happen’d about the 80th, and the _BIRTH_ will (unluckily) happen towards the close of the 8th _Month_. IF _Formation_ happen’d the 45th, _Animation_ follow’d the 90th _Day_, and the _BIRTH_ will succeed about the close of 9 _Months_. IF _Formation_ was compleated the 50th, _Animation_ follow’d the 100th Day, and consequently the _BIRTH_[21] will appear about the last of 10 _Months_; and so of any other certain _Time_, definite _Day_, or stated _Hour_. IT is, in all the above-mentioned _Cases_, to be farther animadverted, that the MALE, as he proceeds from the more _calid_, _siccid_, and _spirituous Seed_, arrives sooner to Perfection in _Formation_ and _Animation_; and is consequently _sooner born_ than the FEMALE, whose _Nature_ is more _cold_, _flaccid_, and _weak_, even in the WOMB: Hence an Allowance of a few Days more or less[22], may be justly made, according to the SEX. [Illustration] CHAP. X. _Of the NUTRITION and POSTURE of the INFANT_. THIS is manifest, that the FOETUS is nourished in the _first Months_, by the _Umbilical Vessels_ only: But the several following _Reasons_ engage me to think; that, in the _latter Months_, it is alimented by the _Mouth_ also, and _That_ by a glutinous _limpid Liquor_: Which, being (probably) secreted from the AMNION for that Purpose, is found to surround it. I. BECAUSE this _Liquor_, which seems very proper for that _Use_, is found not only in the _Mouth_, but also in the OESOPHAGUS and _Stomach_ of the _INFANT_.
