On certain bacteria from the air of New York City.

Dyar, Harrison G. (Harrison Gray), 1866-1929

It was suggested to me by Dr. T. Mitchell Prudden that a promising field for research existed in determining the identity of the bacterial commonly occurring in the air of New York.

Very early in the investigation a practical difficulty in the way of determining species became apparent. It was found, however that the determinations of the species were not always authentic, as seen by the fact that when planted on the standard media many of them contradicted their published characters.
