The ' American Journal of Science' for November, 1863, contains the

or Guano Eock of the Island of Sombrero," recently described as a new 
species of mineral by Dr. Phipson, under the name of Sombrerite, This 
notice is by M. Julian, a resident chemist at Sombrero, who gives a great 
deal of information about its extent and physical characters, disputes the 
accuracy of Dr. Phipson's statements, and asserts that the Sombrero guano 
is as rariable in its composition as any other phosphatic guano, and as little 
entitled to rank as a new species. " Dr. Phipson," he adds, " cannot pos- 
sibly have examined with any care a single cargo, I venture to say not 
even a single ton ; for there is no natural standard by which a represen- 
tative specimen could be ' well cho.=!en* or chosen at all." " On the Nature 
of Jade, and on a new Mineral Species described by M. Daraour," by 
Mr. T. Sterry-Hunt. Geological Survey of Canada : Eeport for 1863.
