EXPLANATION OP PLATE, 



ILLTTSTRATINQ DK. KLBIN'B PAPBR, " OBSERVATIONS ON THE 



STRUCTURE OF CELLS AND NUCLEI." 

 « 



(From the Quarterly Journal of Microscopical Science, for July, 1878.) 



Figures 1-11 (incl.) refer to preparations of stqmnch, 12-20 to 

 those of mesentery of newt. For method of preparing see text. 

 All figures are represented as seen on Hartnack's small stand with 

 eye-piece III, and Zeiss's objective P. 



Fig. 1 represents a goblet cell ; the intranuclear network is well 

 shown, and also the fibrils passing from this into the upper and 

 lower part of the cell. 



FiQ. 2. — The intranuclear network separated from the membrane 

 of the nucleus. 



Fig. 3. — A goblet-cell (like that of 1) as seen obliquely from 

 above, showing the intracellular network. 



Fig. 4. — The intracellular network looked at vertically from 

 above. 



Fig. 5. — Isolated nucleus showing the intranuclear network. 



Fig. 6. — A gland-cell, showing the dense network of fine fibrils 

 of the cell-sabstance ; the nucleus has escaped, but there are still 

 left a few fibrils, probably connecting the two networks, viz., the 

 intranuclear and the intracellular. 



Fig. 7. — ^An isolated nucleus of a gland-cell ; the wall of the 

 nucleus is broken at one place and the intranuclear fibrils are seen 

 passing outwards. 



'- Fig. 8. — A connective tissue corpuscle — endothelial plate — seen 

 in profile ; both the intracellular fibrils and those of the intra- 

 nuclear network are well shown. 



Fig. 9 — A similar cell seen from its broad surface. 



Fig. 10 — Portion of a cell ; the intranuclear network shrunk. 



Fig. 11. — An epithelial cell; the intracellular fibrils are well 

 shown. The top of the cell is seen in an oblique direction, and
