Double, double, toil and trouble, Fire burn, and cauldron bubble- Eye of newt, and toe of frog. Wool of bat, anil tongue of dog, Adder's fork, and blindworm 's sting. Lizard's leg, and howlei's wing — For a charm of pow 'rful trouble Like a hell-broth boil and bubble.
WHY STEW AROUND WHEN MC&B HAS ALREADY DONE IT? We've come u p with 1000 laboratory chemicals that no other supplier bothers with, and we're offering them in our MC&B catalog supplement, Research Chemicals. We don't expect to do much business on these items, but, maybe one of them will save you a couple of hours of synthesizing or purifying on a busy day. If so, we will feel amply rewarded for publishing this catalog supplement. Ask your MC&B Distributor for a copy, or write MC&B, 2909 Highland Avenue, Norwood, Ohio 45212.
