THE INFECTIVE GRANULE IN CERTAIN PROTOZOAL INFECTIONS, AS ILLUSTRATED BY THE SPIROCHAETOSIS OF SUDANESE FOWLS.

If, therefore, the above extract has any meaning at all, it can only mean that these wool-workers acquire slight forms of anthrax which give them immunity; in other words, that the views I have been inculcating for the last half-dozen years are supported by the statistics of the incidence of anthrax. Messrs. F. M. Rimmington and Son, Bridge Street, Bradford, keep a constant supply of Sclavos serum.
