Figure 47.—Large culture forms with processes. × 2000.
Figure 48.—Forms from the gut of the tick with processes. The position of the chromatin
mass on the periphery or even projecting from the parasite is common.
Such forms are not invariably seen. × 2000.
Figures 49&50. —Peculiar forms, stages in the production of the club-shaped bodies. As
the plate was prepared before the true nature of these bodies was appa-
rent, the forms are not well selected to shew formation of the clubs
(see figure in text). × 2000.
Figure 51. —Oval and club-shaped forms from the gut of adult tick. × 2500.
Figure 52. —Double form with achromatic lines, early stage of so-called "copulation"
forms. × 2000.
Figure 53. —A group of developing parasites in the gut of adult tick. Such forms develop
each into a single or more rarely a double club-shaped body. × 1000.
Figure 54. —Bodies resulting from separation of the so-called "copulation" forms. In two
the chromatin is seen, sending out a process probably the rudiment of
the disc (see Plate II, figures 10 and 11). × 2000.
Figure 55. —Double form so-called "copulation" bodies but apparently merely the result
of development of a parasite which was on the point of division when
taken into the tick, (see figure 52, also figure on page 57). × 2000.

Figure 1.—Wall of oviduct, two spermatozoa (sp.) and three club-shaped bodies (p.) Fresh
preparation 1/6 objective.
Figure 2.—Club-shaped bodies from the ovary. Fresh preparation. The upper figures
are mature disc-bearing forms, the lower are leech-like forms shewing
euglenoid movements. × 2000.
Figure 3.—Club-shaped bodies without discs. × 2000.
Figures 4 & 5.—Club-shaped bodies with cusp-bearing discs. × 2000.

Figure 7.—Club-shaped body with disc seen on the flat and the body folded upon itself.

Figure 8.—A club-shaped body shewing vacuoles and diffuse reddish staining of anterior
portion. × 2000.
Figure 9.—Club-shaped bodies similar to those seen in the lower part of figure 2. × 2000.
Figure 10.—Club-shaped body shewing process of chromatin passing forwards to form
disc. × 2000.
Figure 11.—Later stage in the disc formation. × 2000.
Figure 12.—Later development of a double form in which the component parts have not
yet separated. × 2000.
Figure 13.—Three of four forms seen in close connection. × 2000.
Figure 14.—Small club-shaped body. × 2000.
Figure 15.—Double club-shaped body resulting from fission of large fat club forms,—a com-
mon appearance but the significance of which is not known. × 2000.
Figure 16.—Unusual form of club-shaped body. × 2000.
Figure 17.—Club-shaped body apparently with double chromatin mass; but there are
really two club-shaped bodies as in figure 15. × 2000.

presence of the "tail" and the dark area on the periphery correspond-
ing to the disc. × 2000.
Figure 19.—Further stage than above but still shewing situation of the "tail" and disc.
Note also the stellate character of the chromatin seen also in figure 8.

Figure 20.—A young zygote in an embryonic cell. Note the commencing extension of the
chromatin and the more darkly staining nature of the protoplasm. See
also figure 7, Plate III. × 2000.
Figures 21-23.—Growing zygotes. Note the peculiar processes of the chromatin, of which,
owing to their delicacy and complexity, the uncoloured figures give an
imperfect idea. × 2000.
Figure 24.—A zygote breaking up so as to give rise to the appearance of a "sporulating"
body. In this as in the next figure the pale blue protoplasm and the
characteristic chromatin are poorly shewn. Specimen from embryonic
tissue. × 2000.
Figure 25.— A mass of imperfectly divided "sporoblasts" which have replaced the proto-
plasm of an embryonic cell the nucleus of which is visible. Compare
figures 26 and 27 which is the ultimate product of such a condition.
