This Extract is borrowed from the French Journal des Scavans of Febr. 15. 1666. and is here inserted, to excite inventive heads here, to overtake the Proposer in Holland. The letter runs thus:

Some have imployed Deal, Hair and Lime, &c. and therewith lined their ships; but, besides that this does not altogether affright the worms, it retards much the ships Course. The Portugals scorch their ships, insomuch that in the quick works there is made a coaly crust of about an Inch thick. But as this is dangerous, it happening not seldom, that the whole vessel is burnts so the reason why worms eat not thorow Portugal ships, is conceived to be the exceeding hardness of the Timber, employed by them.
We expect with impatience the nature and effect of this Proposition. Many have already ventur'd to give their thoughts concerning it. Some say, there needs no more, but to build Ships of harder kind of Wood, than the usual. Others having observed, that these Worms fasten not to a kind of wild Indian Pear-tree, which is highly bitter, do thereupon sug-
