Chequer-work consists in Angles, Circles and semi-circles &c. which requires no common skill, and time in hewing and laying.

Can deny you nothing, and you may doe what you please with the Notes I send you. You would know of me (you say) what I have observed concerning the Odd Turn of some Shell-snailes with us in England, and the Darting of Spiders.

I will tell you then of the first, that I have found two sorts of them, easily to be distinguisht one from the other, and from all besides, because the Turn of the wreaths is from the right hand to the left, contrary to what may be seen in common Snailes. They are very small, and might therefore well escape thus long the more Curious Naturalists; neither of them much exceeding, at lest in thickness, a large Oat-corne.
