 he was several times bitten, without experiencing any inconvenience; if so, he was more fortunate or less sensitive than any of the spider-tamers with whom we have been acquainted. It was further asserted, that this venom extended itself to the silk which the spider produced; but this assertion was utterly absurd, as any one who has ever applied a cobweb to stop the bleeding from a cut ought to have known. Mr. Bon declared with perfect truth, that the silk, so far from being pernicious, was useful in staunching and healing wounds, its natural gluten acting as a kind of balsam.

The honest enthusiasm of the projector, and the singularity of a regular establishment being formed for rearing and working spiders, excited a considerable share of public attention. It was, indeed, an age of strange speculations, for nearly at the same time a German gentleman broached a scheme for turning tame squirrels and mice to account in spinning; and companies were formed in England, with large nominal capitals to carry out schemes still more preposterous. So important did Mr. Bon's project appear to the French Academy, that they deputed the eminent naturalist, M. Reaumur, to investigate the merits of this new silk-filament.

After a long and patient examination M. Reaumur stated the following objections to Mr. Bon's plan for raising spider-silk, which have ever since been regarded as insurmountable.

1. The natural fierceness of spiders renders them unfit to be bred together. On distributing four or five thousand of these insects into cells or companies of from fifty to one or two hundred, it was found that the larger spiders quickly ''killed and ate the smaller'', so that in a short space of time the cells were depopulated, scarcely more than one or two being found in each cell.

2. The silk of the spider is inferior to that of the silk-worm both in lustre and strength; and produces less material in proportion, than can be made available for the purposes of the manufacture. The filament of the spider's-bag can support a weight of only thirty-six grains, while that of the silk-worm will sustain a weight of one hundred and fifty grains. Thus four or five threads of the spider must be brought together to
