I am so glad to make my review the tenth for this series. So long ago that I'm sure it started as Discovery '61. Anyway, once my family discovered it, my dad would rush home from work and we all watched over supper. The hook for him, and most of us, was Corpuscle. How could Frank and Virginia compete with a dog. Of course, that was the hook to get kids to watch. The science and technology was almost an afterthought. Sure we learned, but, we got to see Corpuscle. It must have been during the early '63 season, ABC aired a one hour primetime special called, I think, This is Discovery. Ostensibly so disinterested parents would see what their kids were watching. They went way back to the beginning shows, which we had missed, showing C. when he was just a pup. In fact, I think the first episode we every watched, while channel surfing, among Chicago's five, in those days, was when we hit on the Discovery Puppy Pen. A screened pen full of puppies, a grown Corpuscle, and, Frank Buxton. I once heard him introduced on a TV show as Dr. Frank Buxton, but, alas. According to his bio, he only has a Bachelor's and a Master's. Virginia Gibson had a pretty good film career, but, not much after Discovery. Nickelodeon just doesn't cut it.
