WEIGHT. A quality in natural bodies, by which they tend towards the centre of the earth.
     2. Under the article Measure, (q.v.) it is said that by the constitution congress possesses the power "to fix the standard of weights and measures," and that this power has not been exercised.
     3. The weights now generally used in the United States, are the same as those of England; they are of two kinds:


     1. AVOIRDUPOIS WEIGHT. 1st. Used in almost all commercial transactions, and in the common dealings of life. 27 1/3 1/2 grains = 1 dram 16 drams = 1 ounce 16 ounces = 1 pound, (lb.) 28 pounds = 1 quarter, (qr.) 4 quarters = 1 hundred weight, (cwt.) 20 hundred weight = 1 ton. 2d. Used for meat and fish. 8 pounds = 1 stone 3d. Used in the wool trade.
     Cwt. qr. lb. 7 pounds = 1 clove 14 pounds = 1 stone = 0 0 14 2 stones = 1 tod = 0 1 0 6 1/2 tods = 1 wey = 1 2 14 2 weys = 1 sack = 3 1 0 12 sacks = 1 last = 39 0 0 4th. Used for butter and cheese. 8 pounds = 1 clove 56 pounds = 1 firkin.
     2. TROY WEIGHT. 24 grams = 1 pennyweight 20 pennyweights = 1 ounce 12 ounces = 1 pound.

     4. These are the denominations of troy weight, when used for weighing gold, silver and precious stones, except diamonds. Troy weight is also used by apothecaries in compounding medicines; and by them the ounce is divided into eight drams, and the drain into three scruples, so that the latter is equal to twenty grains. For scientific purposes, the grain only is used, and sets of weights are constructed in decimal progression, from 10,000 grains downward to one-hundredth of a grain. The caret, used for weighing diamonds, is three and one-sixth grains.
     5. A short account of the French weights and measures is given under the article Measure.

Root fresh and dry weight: Root fresh and dry weights of grafted and non-grafted eggplants decreased under drought and salt stress (Figure 1c, 1d, Figure 2c and Table 2).
The cultivar M7739IPRO presented the highest stem dry weight per plant (41.80 g), followed by ST797IPRO (33.10 g), and M6952IPRO (27.52 g) (Table 4).
microphylla leaves, stem barks, and fruits were determined from the gallic acid standard curve (y=1.9251x + 0.3125, [R.sup.2]=0.9967) and expressed as mg GAE/g dry weight. The total phenolic contents of C.

Results of the analysis of variance showed that the interactions between rice genotypes and treatment of drought stress affected the dry weight of root observed following the first drying stage (day 45 post-plantation) and the second drying stage (day 65 post-plantation).
For morphological characteristics, ten seedlings were randomly selected from each treatment and number of leaf per seedling, leaf sizes, root and shoot length, seedling fresh weight and dry weight and percent moisture content were investigated.
With increasing iron concentration up to 10 ppm, dry weight of aboveground and nodes increased then decreased, while with increasing concentration of iron, grain dry weight had increased (Table 3).
The decomposition (k) was determined by the equation [B.sub.1] = [B.sub.0].[e.sup.-kt], where [B.sub.0] and [B.sub.1] are the dry weight at time [t.sub.0] = 0 and [t.sub.1] = 1, 3, 7, 14, 28, 56, 72 days and t = interval time (in days between [B.sub.0] and B1).
The results for wheat varieties showed that maximum (88.80%) seed germination, shoot length (13.31cm), root length (8.27 cm), shoot fresh weight (3811.90 mg), root fresh weight (330.89 mg), shoot dry weight (235.67 mg), root dry weight (116.56 mg) and seed vigor index (1182.00) were observed in Mehran-89.
