46 TRANSACTIONS OF THE [JAN. 7%, 
mass is penetrated by azurite, but at the same time one may ob- 
serve nodules of tenorite; patches of malachite, in some in- 
stances coarsely fibrous, and in one place a bluish-green concre- 
tion, which forms a new mineral, the so-called calco-malachite, 
of which you have here (8) a larger and handsomer specimen. 
No. 7, above described, is therefore a truly representative speci- 
men of the Bisbee copper region. 
These are not by any means the handsomest specimens ob- 
tained from Bisbee; fine minerals from this locality are by no 
means rare; still, I succeeded in getting some choice material 
from old excavations, such as very beautiful malachitic stalac- 
tites, etc., which may compete with any Bisbee specimens ever 
exhibited. 
Mr. W. H. J. SreBeErG, in behalf of the committee appointed 
to prepare a minute in regard to the late Mr. CHAMBERLIN, 
presented the following report : 
To the N. Y. Academy of Sciences : 
Your committee, appointed to report a memorial and resolu- 
tions on the death of our late member Mr. B. B. CHAMBERLIN, 
respectfully report as follows: 
Benjamin B. Chamberlin, for many years an honored member 
of the Academy of Sciences, and one of its Fellows and Curators, 
died at the home of his brother-in-law, Mr. E. H. Cole, at Nyack 
on the Hudson, on the 13th of October last, in the 58th year of 
his age. Born at Keeseville, N. Y., March 13th, 1831, he was 
sent by his father, Rev. Parmalee Chamberlin, to the Peekskill 
Military Academy to be educated; thence to Irving Institute, 
where he was graduated with high honors in the same class with 
General Adam Badeau. He immediately entered business, 
studying engraving with Benson J. Lossing, the historian. 
After one year’s military service in Ohio, during the time of 
Morgan’s raid, he came to New York and began to devote him- 
self energetically to the collection of minerals, principally those 
of Manhattan Island and vicinity; this he regarded as his life- 
work, completed but a few days before his death by the publica- 
tion in pamphlet form of his list of the minerals of New York 
Island, a paper which he had previously presented at a meeting 
of the Academy of Sciences. 
He was one of the founders and the Treasurer of the New 
York Mineralogical Club, a member of the Agassiz Association 
of Nyack, and also of the West End Natural History Association 
of this city. A lover of nature, he delighted in painting out- 
door scenes, and was quite skilful as an artist, both in oil and
