A, the sacrum.

C to D, about 20 inches in length. 
A few reflections on the above abnormal, or, more properly speak-

entirely nullifies the opinion held by some, that the use of the 
meconium is, in the foetal state, to preserve the passage through 
the intestinal canal, which would otherwise collapse and adhere. 
Now, we find the rectum to be a distinct intestine, and into which 
not one particle or portion of meconium could by possibility enter ; 
yet it is of proper calibre, length, & c., without the slightest adhe- 
sion of its sides in any part ; proving that Nature can make and 
preserve complete the intestinal canal without calling to her aid 
the passage through it of any material or substance. 
Another important fact is shewn, namely, that it is not abso-

that this peculiar excrement should be voided, but that it may be, 
and as in the foregoing instance was, retained with apparent im- 
punity. Does not this farther prove, if proof were necessary, that 
immediately upon an animal breathing the breath of life, the in-
