108 THE ORIGIN OF 



full birth, by Hippocrates^ Brendel[SS) and by 

 Selle ;{9 that a fasciola hepatica has existed in 

 a lamb si'iW in utero ^ [40) that worms have been 

 found in inftmts who have died immediately after 

 they were born, 41) and in sucking animals ;(4:3) 

 it seems that all these favourhble arguments come 

 in support of the opinion of those who believe that 

 worms are innate in man and in other animals. 



If we consider however that the eggs of worms 

 are so small that they are imperceptible even under 

 the tube B, no. 1, of Hoffman's microscope(43) 

 (these eggs are real ovaries or masses of small 

 eggs :) 44) nothing is more probable than that these 

 eggs are absorbed by the lymphatic vessels, that 

 they pass into the circulation, pervade the system 

 with the hlood; and are deposited in different parts

We meet in fact with these worms in the deep- 

 est and most hidden parts of man and other ani- 

 mals, tiiough tiiey ordinarily inhabit only the in- 

 testinal tube.(4;7) 



I think we may conclude with Dr. Panzani,('i:&) 

 that the worms of fetuses are engendered in the 

 womb of the mother by the development of their 

 g>^rms, provided the necessary circumstances wiiich 

 we have pointed out, there concur. (47) Convey- 

 ed with the maternal blood 48) into the humors of 

 the fetus, and accidentally deposited in the intesti- 

 nal cavity abounding in mucus, they are here un- 

 folded, favoured by their position and the viscosity 

 of the miconium. These verminous germs are more
