In conclusion, I think that the observations above recorded 

 show that the material of geological formations need not 

 necessarily have been "laid down " ; it may have been produced 

 in situ like the mud in the ditch round the Park of Marchais, 

 and that the enclosure in it of animal remains may have been 

 in some cases due to a voluntary act of self-inhumation, under- 

 taken, perhaps usually, with a view to self-protection. They 

 also show that two neighbouring strata, the one carrying abundance 

 of life and the other being destitute of it, may nevertheless be 

 contemporaneous in date and conterminous in locality of formation.
