COLUMBITE-Mn Corson Mine, Nottingham, NH 1 mm crystal	Species: COLUMBITE-Mn Locality: Corson Mine, Nottingham, NH Specimen Size: 1 mm crystal Field Collected: Tom Mortimer Catalog No.: u932 Notes: This is a re-photo of my columbite-Mn species top page specimen. EDS analyzed.
GYPSUM Chickering Mine, Walpole, NH 0.3 mm gypsum crystal	Species: GYPSUM Locality: Chickering Mine, Walpole, NH Specimen Size: 0.3 mm gypsum crystal Field Collected: Tom Mortimer Catalog No.: u1395 Notes: This is the classic gypsum crystal shape.
GYPSUM Chickering Mine, Walpole, NH 0.1 mm gypsum crystal	Species: GYPSUM Locality: Chickering Mine, Walpole, NH Specimen Size: 0.1 mm gypsum crystal Field Collected: Tom Mortimer Catalog No.: u1395 Notes: These gypsum crystals are very lustrous.
SCHULENBERGITE Mascot Mine, Gorham, NH 1.8 mm field of view	Species: SCHULENBERGITE Locality: Mascot Mine, Gorham, NH Specimen Size: 1.8 mm field of view Field Collected: Bob Janules Catalog No.: u497 Notes: It is difficult to get definition in the center of this feathery mass. This is a re-photo of my New Hampshire mineral species display specimen.
WHITMOREITE Palermo Mine, N. Groton, NH 1 mm whitmoreite spray	Species: WHITMOREITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1 mm whitmoreite spray Field Collected: Walter Lane Catalog No.: u1270 Notes: This is a redo of a 2015 photo. A tiny rockbridgeite ball is on the left side of the spray.
WHITMOREITE Palermo #1 Mine, Pod 3, N. Groton, NH 0.7 mm whitmoreite spray	Species: WHITMOREITE Locality: Palermo #1 Mine, Pod 3, N. Groton, NH Specimen Size: 0.7 mm whitmoreite spray Field Collected: Forrest Fogg - 1973 Catalog No.: u1425 Notes: This is a redo of a 2015 photo. Forrest Fogg kept good records of which phosphate Pods his material came from.
WHITMOREITE Palermo Mine, N. Groton, NH 1.5 mm field of view	Species: WHITMOREITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.5 mm field of view Field Collected: Walter Lane - phosphate rocks bucket acquired by the MMNE. Catalog No.: u1267 Notes: Multiple whitmoreite sprays, large and small.
ACANTHITE Mascot Mine, Gorham, NH 0.7 mm acanthite spear	Species: ACANTHITE Locality: Mascot Mine, Gorham, NH Specimen Size: 0.7 mm acanthite spear Field Collected: Bob Janules Catalog No.: A Bob Janules collection specimen. TJM photo Notes:

SYNCHYSITE-Ce Parker Mtn. Mine, Strafford, NH Largest hex tablet: 0.4 mm SYNCHYSITE-Ce Parker Mtn. Mine, Strafford, NH Box label	Species: SYNCHYSITE-Ce Locality: Parker Mtn., Strafford, NH Specimen Size: Largest hex tablet: 0.4 mm Field Collected: Unknown - From MMNE 2018 symposium sales table Catalog No.: TBC Notes: Multiple probings of a November 2018 tiny crystal on carbon tape (BC298 - set 21) gave ambiguous and inconsistent results: EDS analysis . I think the Ca is legit. The unlabeled mush around 1.7 to 1.8 KeV may be silicon. The peak just above O may be F. All that can be said from this analysis is that it is an interesting REE mineral. A photo of the label on the micro-box is included. A February, 2019 polished grain EDS analysis , (BC321 - set 23) gave synchysite-Ce the "best fit". So I will catalog this as synchysite-Ce. Tan hex tablets are a common form for synchysite-(Ce). The REE content quantified from this analysis is quite low for synchysite-(Ce). However, parasite-(Ce), another Ca-REE mineral, has twice the REE-Ca ratio.
