Terms of Auxology.* — Messrs. S. S. Bucliman and F. A. Bather 
propose a modification of the terms applied by Prof. Alphous Hyatt to 
the successive ontogenetic stages. 
ITyatt uses — 
1. Embryologic. 
2. Naepionic. 
3. Nealogic. 
4. Ephebolic. 
5. Geratologic. 
a. Clinologic. 
/ 3 . Nostologic. 
The authors 
propose — 
Embryonic. 
Brephic. 
Neanic. 
Ephebic. 
Gerontic. 
Catabatic. 
Hypostrophic. 
Literary equivalents 
are — 
Embryonic. 
Infantine or Larval. 
Adolescent. 
Adult or Mature. 
Senile. 
Declining. 
Atavic. 
The authors offer a justification for proposing these changes, define 
their own terms, and give examples with remarks. As to the word 
Auxology itself, they point out that growth and change do not stop when 
the embryonic stage has been passed, but that owing to this branch of 
science having had no term it is in danger of not being recognized. 
Cyclopian Monsters.! — Prof. C. Emery discusses those cases in 
which paired organs, e.g. eyes or ears, fuse in the ventral middle line in 
the young embryo. Eyes and optic nerves may fuse, and from the un- 
paired eye a tube or proboscis leads to an opening in a closed cavity. 
This tube the anatomists regard as a rudiment of the nose ; zoologists 
will think of the nasal passage of Cyclostoma. Prof. Emery suggests 
that the proboscis corresponds to the nose, plus the hypophysial pouch, 
that the latter has come to be prse-ocular, and that the fusion or close 
approximation of the optic stalks closes the path to the infundibulum. 
He does not believe that hypophysis or nose can be referred to gill- 
clefts, but maintains that the homologues of the oesophageal ring, i.e. 
the optic rudiment and the fore-brain, mark the anterior limit of the 
gill-cleft region. From a teratological standpoint he has some other 
interesting suggestions to make.

Relationships and Role of Archoplasm during Mitosis in the Larval 
Salamander.J — Mr. J. E. S. Moore finds that, with respect to the cells 
which form the undifferentiated genital ridge of Vertebrates, Platner’s 
generalization concerning the spermatocytes of Invertebrates that “ there 
is a genetic connection between the coiled network, the spindle fibres, 
and the archoplasm,” is wonderfully borne out. The archoplasm is an 
accompaniment of the attraction sphere in the leucocytes of the larval 
Salamander, and exhibits a metamorphosis, the known phases of which 
correspond with those in larger and more easily elucidated elements. 
All the cells described by the author are little differentiated, and he 
believes that the ease with which the archoplasm is discernible in the 
reproductive cells has been the sole cause of its association more parti-
