Migrating frogs will tend to colonize a suitable pond within a year or two. If none appear, the pond is either unsuitable or cut off from their migration. If you suspect the latter, introduce some frog spawn taken from a healthy garden pond within, if possible, half a mile of your garden. Do not take frog spawn from the wild.

The chromatographic techniques has been useful for investigations of carbohydrates of animal origin, such as those in human cerebrospinal fluid (90,91), foetal and maternal blood of sheep (202), urines (26,90,134), the polysaccharide components of sea urchin eggs (241), capsular polysaccharides (95), blood group polysaccharides (6,7,10), semm and urinary mucoproteins (94), cornea polysaccharides (258), frog spawn mucin (101), and hyaluronic acid (161).
