The microscopy of vegetable foods, with special reference to the detection of adulteration and the diagnosis of mixtures . e 6 mni. or k-ss in length, and have five printaryand four secondary ribs (Fig. 480). In cross section they are kidney-shajjed. The carpophore is dividi-d. HISTOLOGY. Pericarp, i.

Each consistsof a bundle of elongated cells ending usually in a single rounded cell.These prickles are highly characteristic.The other epidermal cells have wavy walls, and in places are^ longitudinally elongated.Stomata occur in considerable numbers. 2. Mesocarp. A bundle about 50 // indiameter is present in each of the fiveprimary nerves, and a large oil duct, 200H or less broad, in each of the four second-ary nerves. Still larger oil ducts, two foreach carpel, are found in the commissure. 3. Endocarp. The cross cells of thislayer are 7-18 fi broad. Spermoderm. The cells in all but the outer layer are strongly com. Fig. 480.
