two occurring in the same mass in alternate layers in the ratio 
of three to four, the graftonite predominating. Its color is a 
delicate salmon and it crystalizes in the monoclinic system. In 
chemical composition it is a complex phosphate containing 
iron, manganese, magnesium, calcium, lithium, sodium, and 
potassium. 
We hope some member of Section F will be fortunate enough 
to secure a specimen of graftonite for the Institute. 
Miscellaneous Notes. 
In accordance with the purpose of the Institute to extend its 
influence wherever it may be desired, the Council, on May 19, 
recommended an amendment to the By Laws, for the formation 
of ,f branches ” elsewhere. By its provisions, five or mote per¬ 
sons, not residents of Manchester, may organize a branch, which 
shall have the management of its local affairs, and may unite 
with the Institute as an individual member by the payment of 
one dollar admission fee and of three dollars annual dues, the 
branch to receive a copy of the Journal of Proceedings, and its 
members to have the privilege of the Institute rooms, library 
and museum when in Manchester. 
Many New Hampshire people, interested in nature studies, 
have hitherto found it inconvenient to obtain necessary adjuncts, 
such as magnifiers, insect pins, nets, sheet cork, and the like - 
The enterprise of the John B. Varick Company has removed 
this difficulty, as will be seen by the advertisement on fourth 
page of cover. 
Botany is not represented in the present number, but in the 
future the four departments— Mineralogy, Entomology, Botany, 
and Ornithology will receive impartial attention. 
If you think well of this number, and wish to encourage the 
enterprise, send fifty cents and your address to Nature Study,
