ent; the hardness is six to seven and a determination of the spe- 
cific gravity gave 4°149; this result has, however, no great claim 
to accuracy. Nothing is known about the chemical composition, 
so that its true relations must remain in doubt until additional 
material is obtained. The rarity of the species will be appreci- 
ated from the fact that in the past thirty-two years no additional 
specimens have been found, though often searched for. 
4. On the relation of Schorlomite to Garnet.—Dr. K6ni1e has 
recently published the following analysis of a massive titaniferous 
garnet from southwestern Colorado: 
Sid. TiO, Al,O; FeO; CaO MgO CO, 
(G2 3:689)) >), 30501 8-11 2°20 22°67 34°29 0°30 1°48==99°82 
This result can be made to conform to the garnet formula only 
by assuming that part of the titanium replaces the alumina as 
Ti,O, (3°64 p. c.). This garnet resembles the titaniferous melan- 
ites from the Kaiserstuhl described by Knop and the discussion 
has led Konig to the same conclusion in regard to schorlomite 
that Knop and Rammelsberg had reached on the basis of the 
Kaiserstuhl garnets, viz: that it is essentially a garnet containing 
Ti,O, as well as Ti0,. An analysis of the Arkansas schorlomite 
gave Konig: 
SiO, TiO. TieO; Al,O; Fe,.0; CaO MgO MnO 
G.=3°876 25°30 1246 444 1:00 23:20 31:40 1:22 0:46==99:98 
This agrees approximately with the garnet formula; the general 
conclusion seems probably correct.— Proc. Acad. Nat. Sci. Philad.,

Boranitcat Norres.—The numbers of this Journal for January, 
February, and March, 1886, contain an extended paper by Pro- 
fessor Penhallow of Montreal on “ Zendril Movements in Cuecur- 
bita maxima and C. Pepo.” The author has recently sent us a 
copy of a quarto memoir, separately issued from the Transactions 
of the Royal Society of Canada, vol. iv, sect. iv, read May 27, 
1886, on Mechanism of movement in Cucurbita, Vitis, and Ro- 
binia ; also from the Canadian Record of Science, of Oct., 1886, 
Additional notes upon the Tendrils of Cucurbitacece. On looking 
over these two articles, the larger of which enters somewhat into 
the history of the subject and cites a good many publications, we 
find no reference whatever to his own papers published, at the 
author’s particular desire in this Journal. This is the more re- 
_markable as in them Professor Penhallow coins a new term, which 
he continues to make much use of; and an author generally likes 
to date his own discoveries as near to their inception as he can.
