 influential conceptions of faith, a re-commencement of 

 biological researches was especially out of the question. 

 Even when, in the sixteenth century, human Anatomy 

 again began to be studied, and independent investigations 

 of the structure of the body of the developed human being 

 were again first made, anatomists dared not extend their 

 investigations into the condition of the yet undeveloped

 not make too rapid strides. 



It was only when the Reformation broke the all-

 and fresh intellectual impulse began to release enslaved
