sicula in plurality ; (c) podal prolongations with greenish elon- 

 gate " granules ;" (d) tricuspid form of opening of test ; (e) fili- 

 form attachments of animal to the test. Animal 1 -320th of an 

 inch long. 



Fig. 81. Amaha quadrilineata, H. J. C, showing two lateral vesiculaj (a, a) 

 about to discharge themselves independently of the large, appa- 

 rently normal one {h). Animal about 1 -350th of an inch in length. 



Figs. 82, 83. Ckilodon cucullulus, Ehr., two individuals to show linear con- 

 tinuation of circular sinuses in one (82), and the vesicula in its 

 normal position : («) nucleus ; (b) dental apparatus ; (c) vesi- 

 cula ; {d) lines of sinuses. 83. To show apparent absence of 

 vesicula and irregular distribution of contracting sinuses. Animal : 

 largest size seen l-320th of an inch in length. 



Fig. 84. Spirostoma mrens{l), Ehr. Posterior extremity to show dropsical 

 state of proximal sinuses and vesicula ; the former thus presenting 

 the appearance of an areolar structure round the latter. 



Fig. 85. Bursaria leucas (?), Ehr. : (a) nucleus ; (6) vesicula surrounded 

 by six globular sinuses. 



Fig. 86. Himantophorus Charon, Ehr. ; vesicula of, surrounded by dilated 

 proximal sinuses. 



Fig. 87. Euglena spirogyra, Ehr., showing (a) posterior glair-cell with its 

 broad surface upwards, and cylindrical nucleus ; («') anterior 

 glair-cell with its margin upwards ; (6) '* nucleus." Animal about 

 I -133rd of an inch in length. 



Fig. 88. Phacus pleuronectes, Duj. : (a) glair-cell and its nucleus; (6) sup- 

 posed position of " nucleus." Animal 1 -500th of an inch long. 



Fig. 89. Navicula fulva, Ehr., showing the form of its endochrome or 

 organ bearing this colour : (a, «) glair-cells ; {b) nucleus sus- 

 pended by threads to the endochrome, like those of Spirogyra. 

 Frustule 1 -183rd of an inch long. 



Fig. 90. Amphiphora oblonga, H. J. C. (n. sp.?), primary surface showing 

 form of endochrome after division : (a, a) glair-cells ; («') one 

 more magnified. Largest specimen seen 1 -75th of an inch in length. 



Fig. 91. Ditto, lateral view ; the margin is of course angular. 



Fig. 92. Spherical cells or " biliary organisms :" (a) one from Otostoma, 

 H. J. C, containing five or more cellulae filled with a bile-coloured 

 fluid ; (a') one from a binocular Planaria, showing {b) oil-glo- 

 bule, (c) bile-cellulas, (c?) lash of cilia ; (e) another cell from the 

 same Planaria, containing four daughter-cells, each of which is 

 provided with a single bile- cellule ; (/) ditto with a single 

 large bile-cellule in the centre, and several small oil-globules; 

 {g) spherical cell from Brachionus Pala, Ehr., presenting one 

 large bile-cell filled with granules, also a lash of cilia ; this bile- 

 cell has much the appearance of a granulating nucleus. 



Figs. 93-98. Rhizopodous cell inhabiting the protoplasm of the Characeae, 

 under diff'erent phases to show the early stages of the develop- 

 ment of the monads. 93. The cell with single nucleus as it exists 

 in the living protoplasm : {a) pellicula and diaphane ; (6) nucleus 

 in the capsule; (c) sarcode containing moleculae and greenish 

 " granules." 



Fig. 94. Ditto after having taken in food (the green cellules of the inter- 



' ) . . node at its death), which is represented by the dark shade : 

 (a) old pellicula or external cell ; (a') secondary pellicular layer 

 or internal cell; (6) food in the midst of the sarcode, which, with 

 the diaphane, now perishes ; (c) development of plasmic (?) zone 

 round the capsule of the nucleus now become globular ; [d) nu-
