June 26 /47/ Forbes' paper on Cystideæ shows that the encrinites are the parent-forms (these found as low down as any fossils) whence the cystideæ branch out into Echinus & Asterias — It certainly seems very clear that in the oldest formations, every class comes in with high & low forms; in short we have no trace of a beginning.
