PERSONAL AND SCIENTIFIC NEWS. 
Henky William Bristow, F.R.S. died June 14 at the age 
of seventy-two. As early as 1842 he was a member of the 
staff of the Geological Survey of the United Kingdom. 
He was the author of various works on geology and mineral- 
ogy ; he wrote the mineralogical articles in Brande's "Diction- 
ary of Science, Literature and Art" and the articles on minerals 
and rocks in Ure's "Dictionary of Arts, Manufactures and 
Mines." He was the recipient of honors from several geologi- 
cal societies and from some of the crowned heads of Europe. 
Natural Science in the Davenport Schools. From the 
very inception of the Davenport Academy of Sciences the chief 
object has been the advancement of the public interest in nat- 
ural science,especially to secure the most intimate practicable 
co-operation, with the educational system of the city, state, and 
country. To this end it has been the constant effort on the 
part of the Academy to encourage visits of classes and teachers 
with a view of illustrating the subjects at its rooms and of pro- 
moting the introduction of natural science in the school work. 
Recently the Academy devised the plan of a series of visits 
by the several classes of the public schools consecutively 
throughout the year to the rooms of the Academy, under the 
charge of their teachers in each instance, for an illustrated les- 
son on some subject in natural science, the same being contin- 
ued from day to day until all the classes had received this les- 
son in their turn. 
In the city of New York Prof. Bickmore has been successful 
in interesting the authorities of the public schools in the 
American Museum of Natural History, at Central Park, and 
the teachers in the public schools are not only allowed free ad- 
mittance to the collections, but regular lectures are given at 
the museum throughout the year intended especially for the 
qualification of teachers to give instruction in natural science. 
These courses of lectures are largely attended, and have more 
recently extended to other city schools in New York state. 
With this exception the Davenport Academy is so far as we 
know, the pioneer scientific institution in this country to sug- 
gest and execute a plan for thus utilizing its museum and col- 
lections of s()ecimens in natural history, in direct connection 
with the public school, and it seems to open the door to a wide 
range of usefulness for such institutions, and to render such 
collections of a hundred fold more interest, value and direct 
benefit to the community. 
An Immense Deposit of Ice, thought to have its date from the 
glacial period, has been found in Pine Creek canon, Idaho, and 
capitalists are considering the feasibility of mining it for com- 
mercial purposes.
