Now by (non-conception-al) “cloning” is meant the non-spermatic and non-sexual duplication of artificial specimens genetically and sexually identical to the original specimen. 1952 saw the first successful cloning of frogs, from tadpole cells. Professor Dr. J.B. Gurdon, using the Briggs-King technique, cloned a colony of identical South African claw-frogs. He did this by transplanting the nucleus of an intestinal cell from a tadpole (A) into the denucleated egg-cell of another frog of similar species (B). Very amazingly, the thus-stimulated egg-cell divided, and kept on dividing into a blastocystic cluster of several cells (which we here call C & D & E & F etc.).
