certain experiment about weight in air and water a new sovereign of equal  weight in the air to the piece in brass overweigh in the water Grains in three  sovereign the difference in the water be but Grains the same sovereign  overweigh a equal weight of lead Grains in the water in brass Grains for gold  in three sovereign about Grains the same sovereign overweigh a equal weight of  stone in the air at least Grains in the water the Grains be for the weight of  gold in brass metal a glass fill with water weigh in Troy weight ounce and  dram the glass and the water together weigh several videlicet the water ounce  and a half and the glass ounce and a dram a bladder weigh ounce dram and a  half a pebble lie upon the top of the bladder make ounce dram and a half the  stone weigh dram the bladder as above blow and the same fall weigh equal a  sponge dry weigh ounce grain the same sponge be wet weigh ounce dram and  quarter the water weigh in several ounce one dram and a half and the sponge  ounce and a half and quarter of a dram the sponge and water together weigh  ounce and dram in several the water weigh ounce and dram and the sponge ounce  dram and a half three sovereign make equal to a weight in silver in the air  differ in the water for false weight one beam long the other thick the stick  and thread weigh half a dram and grain be lie in the balance the stick tie to  reach within half a inch of the end of the beam and so much from the tongue  weigh grain the difference be grain the same stick be tie to hang over the end  of the beam a inch and a half weigh half a dram and grain exceed the weight of  the say stick in the balance by grain the same stick be hang down beneath the  thread as near the tongue as be possible weigh only grain two weight of gold  be make equal in the air and weigh several dram the one balance be put into  the water and the other hang in the air the balance in the water weigh only  dram and grain and abate of the weight in the air dram and a half and grain  the same trial be make the second time and more true and exact betwixt gold  and gold weigh several as above and make a just and equal weight in the air  the one balance be put into the water the depth of five inch and the other  hang in the air the balance in the water weigh only dram and grain and abate  of the weight in the air dram and grain the trial be make betwixt lead and  lead weigh several dram in the air the balance in the water weigh only dram  and grain and abate of the weight in the air dram and grain the balance keep  the same depth in the water as abovesaid the trial be make betwixt silver and  silver weigh several dram in the air the balance in the water weigh only dram  and grain so it abate dram and grain the same depth in the water observe in  iron and iron weigh several each balance in the air dram the balance in the  water weigh only dram and grain and abate of the weight in the air dram and  grain the depth observe as above in stone and stone the same weight of dram  equal in the air the balance in the water weigh only dram and grain and abate  of the weight in the air dram and grain the depth as above in brass and brass  the same weight of dram in each balance equal in the air the balance in the  water weigh only dram and grain and abate in the water dram and grain the  depth observe the two balance be weigh in air and water the balance in the air  overweigh the other in the water one dram and grain the depth in the water as  aforesaid it be a profitable experiment which show the weight of several body  in comparison with water it be of use in lade of ship and other bottom and may  help to show what burden in the several kind they will bear
