Swedish Weights, used by Bergman and Scbeele. 
The Swedish pound, which is divided like the 
English apothecary, or troy, pound, weighs 
45556 grains troy. 6 
The kanne of pure water, according to Berg- 
man, weighs 42250 Swedish grains, and occupies 
100 Swedish cubical inches. Hence the kanne 
of pure water weighs 48088.719444 English trov 
grains, or is equal to 189.9413 English cubic 
inches ; and the Swedish longitudinal inch is 
equal to 1.238435 English longitudinal inches. 
From these data, the following rules are de- 
duced: 
1. To reduce Swedish longitudinal inches to 
.English, multiply by 1.2384, or divide by0.80747. 
. 2 - To reduce Swedish to English cubical 
inches, multiply by 1.9, or divide by 0.5265. 
3. To reduce the Swedish pound, ounce, dram, 
•cruple, or grain, to the corresponding English 
troy denomination, multiply by 1.1382, or di- 
vide by 8.786. ’ 
4. To reduce the Swedish kannes to English 
wine pints, multiply by .1520207, or divide by 
6.57804. ] 
5. The lod, a weight sometimes used by Berg- 
man, is the 32d part of the Swedish pound: 
1 herefore, to reduce it to the English troy 
pound, multiply by .03557, or divide by 28.1156.

Weights used 4n the several parts of 
Asia, the East Indies, China, Persia, &c. In 
1 urkey, at Smyrna, &c. the) use the batman, 
or battemant, containing six occos, the occo 
weighing three pounds four-fifths English. 
I hoy have another batman much less, con- 
sisting, as the former, of six occos ; but the 
occo only containing fifteen ounces English ; 
44 occos of - the first kind make the Turkish 
quintal. At Cairo, Alexandretta, Aleppo, 
and Alexandria, they use the rotto, rotten, or 
rottoli; at Cairo, and other parts of Egypt, it is 
144 drachms, being somewhat over "an Eng- 
lish pound. At Aleppo there are three sorts 
ot rottos ; the first 720 drachms, making 
about seven pounds English, and serving to 
weigh cottons, galls, and other large commo- 
dities; the second is 624 drachms, used for 
ail silks but white ones, which are weighed 
by the third rotto of 700 drachms. At Seyda 
the rotto is 600 drachms. 
The other ports of the Levant, not named 
here, use some of these weights, particularly 
the occo, or ocqua, the rottoli, and rotto. 
The Chinese weights are the piece, for 
large commodities; it is divided into 100 
catis, or cattis, though some say into 125; 
the cati into 16 taels, or tales, each tale equi- 
valent to 1 j of an ounce English, or the 
weight of one rial and 4-, and containing 12 
mas, oi masses, and each mas 10 condrins. 
bo that the Chinese piece amounts to 137 
pounds English avoirdupois, and the cadi to 
1 pound 8 ounces. The picol for silk con- 
tains 66 catis and f : the bahar, bakaire, or 
barr, contains 300 catis. 
'I onquin has also the same weights, mea- 
sures, &c. as China. Japan has only one 
weight, viz. the cati, which, however, is dif- 
ferent from that of China, as containing 20 
taels. At Surat, Agra, and throughout the 
states of the Great Mogul, they use the man, 
or maund, whereof they have two kinds, the 
king s man, or king’s weight, and the man 
s, mply ; the first used for the weighing of 
common provisions, containing 40 seerf, or 
seres, and each seer a just Paris pound. The 
common man, used in the weighing of merr 
chandise, consists likewise of 40 seers, but 
each seer is only estimated at 12 Paris ounces, 
or | of the other seer. 
1 he man may be looked on as the common 
weight of the East Indies, though under some 
difference of name, or rather of pronunciation, 
it being called mao at Cambaya, and in other 
places mein, and maun. The seer is pro- 
P eil y the Indian pound, and of universal uses 
the like may be said of the bahar, tael, and 
catti above-mentioned. 
The weights of Siam are the piece con- 
taining two shans, or cattis ; but the Siamese 
catti is only half the Japanese, the latter con- 
taining 20 taels ; and the former only 10* 
though some make the Chinese catti onlv 1(3 
taels, and the Siamese 8. The tael contains 
4 baats or ticals, each about a Paris ounce * 
the baat 4 selings, or mayons ; the may on 2
