    of a cavity with masses of bacilli at the edge. X 100. (Hartnach's No. 4, Zeiss's N 0. 2 eyepiece, Abbe's condenser.) Fig. 4.—The structure in the lung referred to at p. 298. X 200. (Hartnach's No. 5, Zeiss's No. 2 eyepiece, Abbe's condenser.) Ftg. 6.—Toussaint's micrococci. X 950. Zeiss's ^^ih. oil immersion, No. 4 eyepiece. Abbe's condenser.) Fig. 6.—Psorospermioe from the liver. Experiment I., No. 2. X 330. (Hai-tnach's No. 7, Zeiss's No. 2 eyepiece, Abbe's condenser.) Fig. 7.—^Alveolus filled by a giant cell containing several bacilli. Experiment XIV., No. 3. X 330. (Hartnach's No. 7, Zeiss's No. 2 eyepiece, Abbe's condenser.) PLATE II. Fig. 8.—Section of fibrous part of lung from which Fig. 2, Plate I. was taken, showing giant cells, one of which seems to be forming a blood-vessel. No bacilli are present among the fibrous tissue or in the giant cells. The advantages of flooding the field with light by means of a condenser properly employed is well seen, for nothing but the stained bodies is visible, though in reality the main mass of the field consisted of dense fibrous tissue. X 330. (Hartnach's No. 7,- Zeiss's No. 2 eyepiece. Abbe's condenser.) Fig. 9.—Section of kidney at margin of tuberculous mass showing kidney tubule containing a mass of caseous material with numerous bacilli. Experi- ment XIV., No. 1. X 330. (Hartnach's No. 7, Zeiss's No. 2 eyepiece. Abbe's condenser.) Fig. 10.—Tubercle bacilli. X 2,350. (Powell and Lealand s ^^th oil objective N.A. 1-38.) . , .J . Fig. 11.—Wall of cavity in case of phthisis showing the epithelioid tissue between the caseous mass and the inflammatory tissue. Bacilli in the epitheUoid cells resembUng somewhat the appearance of the bacilli in leprosy as regards their arrangement. X 330. (Hartnach's No. 7 objective, Zeiss's No. 2 eyepiece, Abbe's condenser.) „ „ , x - i j Fig 12.—Tubercles in the lung showing the alveoli full of caseous material and bacUli. X 330. (Hartnach's No. 7, Zeiss's No. 2 eyepiece, Abbe's condenser.) Fig. 13.—Tubercle in the lung showing epithelioid cells in alveolus surrounded by thickened wall of the alveolus. Three bacilli in the centre of the epithelioid mass. X 330. (Hartnach's No. 7 objective, Zeiss's No. 2 eyepiece. Abbe s condenser.)
