QUARTERLY CHRONICLE. 279 
according to the “nidus”’ in which they are developed, is a 
highly important field of research. Professor Hallier’s work, 
‘Die Pflanzlichen Parasiten des menschlichen Korpers,’ 
published at Leipzig in 1866, is one of the latest on the sub- 
ject. In English we have nothing written which is well up 
to the time. The study of these forms by cultivating them 
under the field of the microscope is of great importance, 
bearing so largely as it does on the possible variations of 
species and their origin. 
6. “ A Contribution to the Knowledge of Miescher’s Sacculi,” 
by Professor W. Manz, of Frieburg. 
7. “On the Structure of the Connective Tissue of the 
Eyelid,’ by Dr. Ludwig Stieda, Professor in Dorpat, illus- 
trated with half a plate. 
8. “ A Gas Chamber for Microscopical Purposes,” by Dy. 
S. Stricker.—The author feeling the great importance of such 
researches as those of Recklinghausen on the action of car- 
bonic acid on blood, and of Kiihne on the action of gases on 
the cilia of the ova of Anodonte (Max Schultze’s Archiv, 
Bd. II, p. 137, and p. 373), has devised a small instrument to 
place on the stage of the microscope, by means of which a 
smail object may conyeniently and efficiently be subjected to 
the action of a gas. A woodcut of the instrument is given— 
which may be more fully described hereafter. 
9. “Remarks on the Structure and Development of the 
Retina,” by Max Schultze. 
10. “ On the Action of Quinine on Protoplasmic Move- 
ments,” by Dr. C. Binz.—Inquiries of this nature are of 
very great importance, and tend directly towards the explana- 
tion of vital phenomena. More of this kind of work might 
be done by English microscopists. Dr. Binz has studied the 
action of quinine on the movements of Vorticella campanula, 
Actinophrys Eichornii, and Ameba diffluens, of the white 
blood-corpuscle, and of the currents in Zradescantia virginica. 
He has also made some experiments with morphia and 
strychnine. The writings of Max Schultze and of Ktihne on 
Protoplasm are referred to and discussed. 
11. ** Spongological Note,” by Oscar Schmidt. 
12. “A Reclamation, touching the formed Sarcode (‘ geformte 
Sarcode’),” by Oscar Schmidt. 
13. “* On Actinophrys Eichornii, and on a new fresh-water 
Rhizepod,” by Dr. Richard Greef. 
14. “ On the Terminal Organs of the Optic Nerves in the 
Eyes of Annulosa,” by Max Schultze—This is a brief note 
discussing the conclusions of Leydig in his beautiful illus- 
trations of the neryous system of Annulosa lately published.
