and twist themselves readily enough. All the difference was in the colour, 

 these being much whiter than any I have seen from the guts. Vid. Barthol. in 

 Hist. 60, Cent. 5, where near 20 worms, as long as my finger, were found in 

 a lady's arm, probably of this species too. 



The Undertakings of Mr. Henry Bond, senior, a famous Teacher of the Art of 

 Navigation in London, concerning the Variation of the Magnetical Compass 

 and the Inclination of the Inclinatory Needle ; as the Result and Conclicsion of. 

 38 Years Magnetical Study. N^ 95, p. 6065. 



Mr. Bond can show the cause of the variation of the magnetical needle, or 

 compass, by the motion of two magnetical poles ; how these poles are found ; 

 and what their distance is from the poles of the earth ; what their annual mo- 

 tion is, and from whence it proceeds.— By calculation he finds all the variations 

 that have been observed at or near London, for above 90 years past ; and so by 

 consequence it may be found at London to the end of the world. — He has cal- 

 culated a table to every 5 minutes of the inclination of the inclinatory needle ; 

 so that by the needle's inclination, and that table, and the latitude of the place, 

 he can find the longitude of any place in the world. — By that table also he finds 

 Mr. Robert Norman's inclination, which he found An. 1576; and can show 

 what will be the greatest and least inclination of the inclinatory needle, in any 

 latitude in the world. — He has 4 examples of finding the longitude by the help 

 of the inclinatory needle ; one at Balsora in the East Indies, in the year 1657. 

 Another at Cape Charles, on the coast of Virginia before that time. The third 

 at the Cape of Good Hope. The fourth at the Straits of Magellan. 



On a pleasant Way of catching Carps. By Mr. John Templer. 



N° 95, p. 6066. 



A gentleman invited me to walk with him to his fish-ponds, and to see a boy 

 throw out carps with his hands, at any time in the heat of the day. I saw four 

 very large ones, that the boy took. His way was this : he waded into the pond, 

 and then returning to the sides, he would grope them out in the sedge or 

 weeds, and, tickling them with his fingers under the belly, quickly remove his 

 fingers to their gills, and throw them out upon the land.* 



* This trifling paper is littie worth preserving. The " pleasant way of catching carps" relates 

 merely to what is now well known j viz, that carps, and, it might be added, many other fish, in 

 warm weather, are sometimes so indolent as to suffer themselves to be gently handled, and may 

 consequently be easily seized and taken out of tlie water.
