“But this was but this dayes businesse: for, as this had not beene enough to performe to their friend departed, to this place and to this end (that is, prayer, and other funerall devotions) some of them came every morning and evening at sixe and sixe, for the space of a moneth together; and had come (as it was then imagined) the whole time of their abode here in England, had not the rudenesse of our people disturbed and prevented their purpose.”

Clouds.
Clouds are defined to be a collection of vapours suspended in the atmosphere, and rendered visible.
Although it be generally allowed that clouds are formed from the aqueous vapours, which before were so closely united with the atmosphere as to be invisible, it is not easy to account for the long continuance of some very opaque clouds without dissolving; or to assign the reason why the vapours, when they have once begun to condense, do not continue to do so till they at last fall to the ground in the form of rain or snow, &c. It is now known that a separation of the latent heat from the water, of which vapour is composed, is attended with a condensation of that vapour in some degree; in such case it will first appear as a smoke, mist, or fog; which, if interposed between the sun and earth, will form a cloud; and the same causes continuing to operate, the cloud will produce rain or snow. It is however abundantly evident that some other cause beside mere heat or cold is concerned in the formation of clouds, and the condensation of atmospherical vapours. This cause is esteemed in a great measure the electrical fluid; indeed electricity is now so generally admitted as an agent in all the great operations of nature, that it is no wonder to find the formation of clouds attributed to it; and this has accordingly been given by Beccaria as the cause of the formation of all clouds whatsoever, whether of thunder, rain, hail, or snow.
