end of March and April last, we had much and violent thunder and lightning, 

 which had this unhappy effect on all the parcels of wheat and rye of the last year's 

 growth, that, though over night they were dry, sweet, and fit for shipping, the 

 next morning they had lost all these good qualities, and were become clammy 

 and stinking, and consequently unfit to be shipped away for the present : so that 

 the owners were forced to cause It to be turned over two or three times a day; 

 and yet it required six weeks, if not longer, before it was recovered. 



This Is a thing which often happens to corn that has not lain in the granary a 

 whole .year, or not sweat thoroughly in the straw before It be thrashed out. An 

 accident little noted, yet In my judgment worth the enquiring Into. For, though 

 the alterations caused by thunder in liquors, be taken notice of, and probable 

 reasons given for them ; yet I judge this somewhat more abstruse, and therefore 

 more worth while to be considered.

In this narrative it is stated, that a minister, 50 years of age, was troubled 

 with an indisposition, attended with sickness and vomiting ; of which he was 

 liable to relapses after the exertion of preaching. What he brought up In one 

 of these relapses resembled tallow, 4 pieces of which weighed i an ounce.

This letter of Mr. Flamsteed, to M. Cassini, contains an account of some' 

 observations made by the former, on the planet Jupiter and his satellites, also 

 on the planet Mars, stating the motions, periods, and distances of the satellites, 

 from Jupiter ; though in a less accurate degree than that which they are known 

 at present. Mr. F. deduces from his observations, that the parallax of Mars 

 is 25" ; and that consequently the solar parallax is about 10"; and therefore the 

 sun's distance from the earth is 21000 of the earth's semi-diameter; this being 

 too little, or the parallax too great, by about the 5th part, according to later and 

 more exact observations.
