suitably curved surfaces. 3) Point projection whereby electrons are focussed to a fine spot on a thin target which then becomes a source of X-rays to project a magnified image of an object by rectilinear propagation, and 4) scanning methods whereby a fine electron beam probe is made to scan point-by-point the surface of the object itself or a thin metal target in close contact with the object. ...

In 1946 Hale (1) described a histochemical method for the detection of acid polysaccharides in animal tissues, based on the ability of these compounds to bind ferric ions, which were subsequently detected as Prussian blue. It has been possible to adapt this histochemical method to the quantitative determination of acid mucopolysaccharides on a macro or micro scale. The major modification of the...
