PHYSIOLdGICAL. 
Gen. Sub. 59 
light increasing susceptibility of animals to cholera and typhoid bacilli. 
Question as to the effect of light on anti-toxins ; Frankland (214). 
Presence of iron-compounds other than haemoglobin and haematins in 
chromatin of animal and vegetable cells; Macallum (415). 
Phagocytosis; De Bruyne (83). — Phagocytosis in Orthoplera ; 
Cuenot (125). — Phagocytic glands in Myriopods ; Kowalevsky (359).— 
Function of Amoebocyteg in Polychceta ( Leiocephalns leiopyyos). Trans- 
port excretory granules and deposit them as pigment in epidermis. May 
also withdraw and digest accumulated reserve substances ; Racovitza 
( 545). — Excretion in Orthoptera , by malpighian tubes, by pericardial 
cells, and by certain colls of the corpora adiposa, which store urates ; 
Cuenot (125). — Excretion in Holothurians ; Schulz (640). — Excretion 
by means of a sortie of leucocytes, carrying particles from degenerated 
elements, functioning organs, or intrusions, is a normal process in 
Lamellibrauchs ; De Bruyne (83). 
Swim-bladder of fishes ; Dei (144), Richard (576). — Function of 
swim-bladder; Bonnier (54). — Static action of swim-bladder; Reg- 
nard (568). — Air-sacs of birds ; Dei (144). — Marine animals, small 
specific gravity of vacuolar fluid ; Brandt (66). 
Luminosity of pelagic Copepods. Physiological processes are involved 
only to the extent of producing the luminous substance, and placing it 
in the conditions, e.g ., contact with water, required for its being lumi- 
nous. Utility perhaps to mislead ; Giesbrecht (246). — Luminosity : 
a pair of spots on pleura of 8th abdominal segment in larva, nymph, and 
imagines (both sexes) of Phosphcenus hemipterus. So, too, in larva of 
Lampyris noclihtca. In Lamprorhiza splendidula , three corresponding pairs 
of spots in larva, nymph, and female imago ; a fourth and fifth pair Added 
in the nymph stage. The luminosity requires to be incited by nervous 
stimulus ; Yerhoeff (708a). 
Hibernation ; Dubois (161, 162). — Heat regulation in hibernation ; 
Pembrey & Hale White (519). 
Respiratory exchange in lower marine Invertebrates ; Vernon (709). — 
Carbonic autonarcosis ; Dubois (163a). 
Pigmentation . 
Classification of chromatophores : — 
I. Autoplastic form, changes intrinsic — 
(1) Holoplastic, contractile as a whole, e.g., Ctenophora , Isopoda. 
(2) Endoplastic, inner protoplasm alone contractile, e.g., Verte- 
brata, certain Pteropoda. 
II. Alloplastic form, changes extrinsic, e.g., Cephalopoda , certain 
Pteropoda ; Garstang (234). 
Possible origin of haemoglobin from chromatin of nucleus ; Macallum 
( 415). — Relations between abnormal pigmentation and changes in the 
nervous system ; Cauer (96). — Contributions to the study of skin- 
pigraent; Grimm (261). — Critical discussion of recent researches oncolora-
