The Parallaxes of / and 6 Cassiopsiz, Deduced From 
Rutherford Photographic Measures. 
The results obtained are as follows: 
Parallax of yu Cassiopeize = 0.275 + 0.024 
Parallax of 6 Cassiopeize = 0.232 + 0.067 
The paper will appear in the Annals of the Academy. 
Prof, Rees made a few remarks on the above paper, after 
which Prof. Grorce E, Hate, of the University of Chicago 
described some of his recent investigations in solar physics. 
Prof, Hale exhibited lantern slides of the apparatus used by 
him at the Kenwood Observatory, and some very remarkable 
photographs of prominences and faculz which he has obtained

cluding : 
(A) A carrier of cover impressions (mycoderm blood), 
utilizing as clamps a coil of brass wire mounted in a 
phial. The same device, with a platinum coil, serves 
as a convenient staining phial for cover glass prepara- 
tions. 
(B) A suggested medium for mounting delicately contrac- 
tile protoplasmic objects, 
(C) Devices for avoiding inelusion of air-bubbles in 
mounts, 
(D) Balsam-paraffine as a ring varnish.

Amphibia.” In the seventh a dorsal root was shown to pass off 
into a branch representing Ophthalmicus superficialis facialis and 
Buccalis of Fishes, and innervating the lateral sense organs cf
