We adopted the protocol that he gives in his 1868 monograph around the early advancement of the hen. The protocol explained by His unsuccessful, in our palms, to generate sections of the standard that he illustrates in his monograph. Generally, the tissue disintegrated when sectioned on account of weak infiltration with the wax. Usable sections could only be attained if His’s protocol was modified by melting the embedded embryos in fresh paraffin wax. 1 explanation for our conclusions is we failed to faithfully replicate His’s protocol. Yet another is always that his protocol was incomplete. We suggest that His is probably going to obtain uncovered and perfected infiltration embedding with paraffin wax but did not publish a full protocol.
