From the analysis is deduced the oxygen ratio for the

25. a Transparent Garnet from Jordansmithl in Silesia; b 
Mr. Wensxy of Breslau.—This garnet is colorless and has G.—= 
3609. The form is the dodecahedron, but with a very obtuse 
tetrahexahedron 2-84. It afforded Websky on analysis, 
Si 37:88, 41 21-13, Fe 4°19, Mn 0-45, Ni 0-28, Mg 2:88, Ga 31-28, H 1-08=99.17; 
Whence it is essentially an alumina-lime garnet. 
26. On the composition of the vapors or gas escaping in 
the Phlegrewan Fields and other places near Vesuvius ; by Mr. 
Gorcrrx.—At the great Solfatara, the gas of the 20th of July 
crystallization and easy basal cleavage. G. = 3-2. Composition 
er, 
0'7, nitrogen 4°35, On the 24th, 11S 5-0, CO? 80-0, O 2-7, N 123, the 
temperature of the gas was 110° to 120°C. On the 25th the gas 
afforded HS 10-0, CO® 73-3, O 8-0, N 13°72. 
At the Grotto di Zolfo the gas from the entrance consisted of 
HS 4°7, CO? 88-2, O 0-7, N with combined gas 6°4; and that from 
the interior gave for the same ingredients the numbers 5:7, 87°8, 
07, 5°8, The gas from the baths at Lake Agnano, taken on the 
24th of July, afforded in two analyses, CO? 83-3, 86-9, O 4:1, 2°0, 
N 12°6, 11-1, with a trace of HS in the second. In other portions 
there was less of carbonic acid and more of atmospheric acid. 
t Torre d 
the recent eruption afforded HS 20-0, CO2 91°5, O 0-7, N with com- 
bined gas 7:8. [These numbers do not foot up 100, and either that 
for HS or that for CO must be 20 or less in error]. At Chiata- 
mone the gas consisted of CO? 82-1, 01:7, N 162.—Ann. Ch.

27. Note on Rhinosaurus ; by O. C. Marsu.—In the June num- 
ber of this Journal (p. 461), I proposed the name Fhinosaurus 
for a new genus of Mosasauroid reptiles, As this name proves to 
be preoccupied, it may be replaced by Zylosaurus. The name 
umphosaurus, since suggested by Prof. Cope, cannot be retained, 
4S It was given to a genus of lizards in 1843 by Fitzinger.
