42 . Inquiries into Coloured Ligbi. 



till they return to their ufual place of relidence. As the 

 fwine which have been pierced float every where around, 

 they are picked up and put into larger boats, which follow 

 for that purpofc. 



If thele hunters fall in with any ve{rcl.>^ belonging to the 

 Chinele, of whom a great many are fettled at Malacca, and 

 •who on fi/ch occafions become ready purchafers of their 

 booty, they fell to them their fwine, and receive for thofe 

 that have an inch and a half thicknefs of lard on the breaft 

 at the rate of a pialter a- piece. It may readily be believed 

 that none of them are pinxhafed by the Malays; for, being 

 Mahometans, they abhor fwine's fled^, and, confequently, 

 thefe pagan fwine-hunters; to whom they do all the mifchief 

 they can, bv deltroying their huts, robbing them of their pro- 

 perty, and often alfaflinating them, without ever being- called 

 to an account by any one for their depredations. 



Of the fwine which they cannot fell, they firft cut off the 

 head ; they then (kin them and cut them up, chiefly for the 

 fake of the lard, but fave as much of the flerti as may be ne- 

 ceflary to feed their dogs, and throw the reft; into the fea. 

 They then row their boats, laden with lard, to a folitary 

 place on the coafl; unfrequented by the Mahometan Malays, 

 where they melt the lard, and preferve the greafe in large 

 earthen vefl!els, or bojans, which are manufactured in Siain. 

 This greafe they fell to the Maki Chinefe; and it is ufed not 

 only bv the common people inftead of butter, as long as it is 

 not rancid, which is fcldom the cafe in Malacca, but alfo 

 for burning in their lamps inflead of coco-nut oil.

SIK, 



SEND vou niv paper on coloured light; an hypothetic 

 theorem inftituted to prove, not afluming to have proved, 

 that there i? hut one primarj colour in our folar fyliem, and 

 that all the rcil ii the prifnuitic image are, on one fide of the 

 fcale, only gradations of that colour toward? pure light; and, 

 on the other lide the fcale, merely degradations from light 

 towards the aclual abfenc.e of it; and that green exilts only 

 as an intermediate compound between the two.
