pots, in a mixture of loam, peat, and sand ; and, insummer, it succeeds best by being placed out withthe alpine plants.

A somewhat curious enquiry was instituted, inGermany , a few years ago, regarding the relativeproperties of differently coloured plants; of thoseodorous and inodorous; agreeable and disagree-able ; distinguishing these latter qualities as theyexist amongst plants of different colours. Upwardsof four thousand species were examined, and theircolours and qualities registered. The Campanulas appeared to be amongst those which were mostdeficient of white flowers, and those wantingfragrance. Little more than four in a hundredwere white; and about one in a hundred onlypossess smell. This instance, however, was foundto be at variance with the general rule, as deducedfrom all the plants examined. Amongst the totalnumber, white flowers were most abundant; nextto these, yellow; and then red; the difference notbeing great between them. Of all other coloursand intermediate shades, the numbers proved to bemuch less. White flowers were not only the mostnumerous, but they also proved proportionably themost fragrant. Amongst coloured flowers, the redhad the greatest, and the blue the least, tendencyto the formation of odoriferous substances. On theaverage, there appeared to be only one odoriferousspecies in ten. Again, it appeared that amongstthe white flowers which were odorous, not morethan one in fifteen were disagreeable; but, oforange and brown flowers, by far the greatest por-tion proved to be offensive.
