28 wide-bore glass tubing. We heat this in the blow- pipe flame until it becomes very plastic ; then making a sharp outward turn with the right wrist, bend the tube round through a right angle, giving it the proper flattened conformation : and then draw out into a long flat capillary stem (fig. 8, A). We cut this through at the point where it begins to lose its flattened conformation : and so leave attached to
