h'ig. .'lO. EuyJena viridis, after tlic formation of ovules ; iudiviiluals still 

 adheriiii; to eaeh other and to the watch-glass in which this was 

 ol)serve(l. 



Fig. 51. lUtto, subsiding into sjdierical cncystment. 



Fig. >y2. Ditto, encysted, (.\ltliough one of each of these pairs is left 

 blank, both individuals were alike in nature.) 



Fig. .5."i. CrumenHlu texta, Duj., showing sarcode and its granules, nucleus. 

 vesicnla, red body, and (a) glair-cell ; {b) glair-ccll more mag- 

 nified to show its nucleated character. Length of animalcule 

 about l-5(i()th of an inch. (For a figure of tlie same filled with 

 ovules or " embrjonic cells," see loc. cit.) Ovules about l-2i300th 

 of an inch in «liaraeter. 



Fig. .j(). Ditto, effete, containing ovules endowed with locomotive power; 

 probably from the development of a cilium. which in this instance I 

 eoidd not see for want of a microscope of higher ])ower. (6, b) red 

 grains,rouud,composedof material like that of the red body; {c,d,e) 

 different phases of the ovule of this specimen more magnified. 



Fig. 5/. Euglena viridis (large sj)ecimen) encysted and filled with ovules. 



Fig. .^H. Internal, transparent, tough sac holding the ovules (jn-obably a 

 transformation of the ])areut) : (a) portion of the contents of the 

 sac to show that they consist of ovules of diiFerent sizes, and 

 granules. 



Fig. 5\). Ovule more magnified to show its oblong or quadrilateral form in 

 Euglena riridis : (a) capsule ; (6) film of homogeneous matter 

 lining its interior ; (c) pellucid area with central granule. (This 

 ovule has somewhat progressed in develo])ment.) 



Fig. ()<). Effete cell of Crunienula texta, showing that it possesses a ske- 

 leton cell composed of sigmoid fibres arranged s])irally, so as to 

 assume a conical form: (a) end view; (b, c) form of fibres; 

 {d) ])ortion of a broken cell. Is not this analogous to the spiral- 

 fibre of the vegetable cell? 



Fig. Gl. Longitudinal dedujdication of Euglena viridis during active life. 



Fig. 62. Euglena agilis, II. J. C. (n. sp. ?j, from the brackish water of the 

 marshes of Bombay : (a, b, c) Frolococcus or still-form after 

 having been kept in a watch-glass and sujjplied with fresh water ; 

 ( a) transverse division showing that the red body is not deve- 

 loped in the lower half; (c) ditto quadruple, longitudinal divi- 

 sion showing that the red body is equally inulti])lied ; {d) linear 

 development (probably by longitudinal division, as the red body 

 IS jjre.sent in each cell). Animal l-fjUOth of an inch in length. 



Fig. <ii}. Serpicula rerticiUata, Roxb. Spine-cell of leaf showing tlie proto- 

 ])lasmic cell or ])rimordial utricle of Mohl. (a) nucleus ; (b) green 

 granules m the reticulate molecular jjrotoplasm (the former cor- 

 responding to the " granules," and the latter to the molecular 

 sarcode of the amuibous cell, figs. 1, 2) (?). 



Fig. <>1. Ditto, cell of body of leaf showing protoplasmic cell in rotatory 

 motion, carrying round with it chlorophyll-bearing cellules (|)ro- 

 liably only an enlarged form of the green granules of the spine- 

 cell, fig. (i.Jj, imbedded in the protoplasm promiscuously. These 

 two figures are for comjjarison with the amoebous cell, figs. 1 & 2. 



Fig. (io. Paramecium aurelia, lihr.: (a) granules; (6) digestive globules 

 containing food; (c) buccal cavity drawing in particles of food 

 f<jr the formation of tlie new digestive globule at its lower extre- 

 mity. Length about l-17(>th of an inch. 



Fig. C>(]. Ditto ; diagrammatic view under compression, showing (a, n) vcsi-
