Generation of Animals from Animalcula in 
Semine Mafcolino. By Dr. Martin Lifter, 
Fellotp of the Colledge of Fhyftcians and Royal 
Society. 
Exerdt Anat. tert. p. 1x4. 
AmongH the many Arguments mhkh I have ufed to cm'^ 
fute the Opinion of Mr. Leewenhoeck ahout the Gene'- 
ration of Animals from innumerahle little Animals in 
Semine Mafculino, one I omitted^ which is as follows t 
RUrfus qusero, fi humanum corpus nafcatur ab ani- 
malcqlo e (emine mafculino unde fint ifta animalcu* 
la genita? & quidem generantur ad plurimos annosi 
fcilicet ab adulto viro ad extreoiam ufq; fenedlutem ; 
certe a coitu perado looge maxima eorum pars ejicitur ; 
unde novaibboles indies (uccrefcat, necefle eft. An ve- 
ro hsec animalculorum proles fere diurna a (ui fimilibus 
animalculis generentur, vel fponte nafcantur ? Pofterius 
te, Leewenhoecke, exiftimare baud facile credo, quia tu, 
ii quis alius, automata mirifice coofutafli : fi prius ver6 
putes ipfa etiam ilia animalcula, dum in femine mafculi- 
no funt, adulta efle fequerur, quod generare potes funt. 
At quam abfurdum hoc fit, tute cogita fcilicet eadem 
animaliabis adolejcere, nempe femel in femine mafculino, 
atq,-iterum in humano ftatu atqj conditione*
