inclosed in the skin of the fat globules, but the skin itself was reduced to a 

 fluid matter; then viewing it with attention, I perceived, when the melted fat 

 was cold, that there were different matters inclosed in the fat globules; as there 

 appeared an inconceivable great number of exceedingly small coagulated particles, 

 and the rest of the parts, of which the fat was composed, lay in one smooth 

 and even substance. 



By the microscope, I saw that the fat particles had such dents in them, as 

 I have shown, are in the globules of flour of wheat : from which I am con- 

 firmed more than before in my opinion, that the fat globules might be separated 

 intirely, or in part, from the skin with which they are surrounded, by opening 

 the dents, without breaking the skin. I took off^ the thin membranes, which 

 encompassed the fat particles, and viewing them with a microscope, observed 

 that the fat particles had imprinted a roundish figure on the membranes, in- 

 clining to a hexangular shape; but in other parts they were of an oval figure. 



I took a flat fish, called plaise, and took off the fat which adhered to the 

 vessels, or bones, and viewed it with a microscope, and observed, that the fat 

 particles were of several sizes ; and some were so small, that I judged that 50 

 of the least were no larger than one great fat globule; and I also saw that 

 many of the fat globules had such a dent in them, as we find in the meal or 

 flour of those little white beans, which we call French or kidney-beans. 



Concerning a new Island lately raised out of the Sea, near Tercera. Bi/ 

 Tho. Forster, Esq. N° 3/2, p. 100. 



John Robinson, master of a small pink-snow, from Piscataqua in New- 

 England, arrived at Tercera,* Dec. 10, 1720; near which island he saw a fire 

 break out of the sea. Dec. 18, we got under sail at 12 o'clock at night, and 

 stood from Angras, S. E. The next day at 2 in the afternoon, we made an 

 island, all fire and smoke; and continued our course till the ashes fell on our 

 deck, like hail or snow, all night. We bore from it, the fire and smoke roar- 

 ing like thunder, or great guns. At day-break we stood towards it again : 

 at 12 o'clock we had a good observation, 2 leagues south from it. We sailed 

 round it, and so near, that the fire and matter it threw out, had like to have 

 done us damage: but a small gale, at S. E. sprung up, and carried us clear, 

 to our great joy. The breeze was accompanied with a small shower of rain, 

 which caused a great dust to fall on our deck. With this breeze we stood 

 away for Tercera. The Governor informed us that the fire broke out Nov. 20, 

 1720, in the night, and that its prodigious noise caused an earthquake, which
