It definetly looks like 4 references: The 2 vital records references with out volume or page numbers may refer to citatations in the NER article. The War Department reference could also refer to a citation in that article: could be Civil War or other pension files, or just about anything, ealier ciations were sometimes very sparse. There was a cite connected to rootsweb somehow (it may have been in Blacktone) that had the full text of NER, you might just try putting the full title NEW ENGLAND HISTORICAL GENEALOGICAL SOCIETY REGISTER in your favorite search Engine and see if it comes up (caveat:I'm not sure how you spell the exact name of the Journal). Russ NB: best guess is that the NER article is titled some thing like extract of Mendon Mass Vital Records.
