They may use up all the protoplasm of the rod in their formation, or they may use only a small part of it, the rod which forms them continuing its activities in spite of the formation of the spores within it. They are always clear and highly refractive from containing little water, and they do not so readily absorb staining material as the ordinary rods.
The very simplest forms, in common with the spores and gemmules of the higher ones, are as nearly as may be of the same specific gravity as the water in which they float; and though it cannot be said that among aquatic creatures superior specific gravity is a standard of general superiority, yet we may fairly say that the superior orders of them, when divested of the appliances by which their specific gravity is regulated, differ more from water in their relative weights than do the lower.
It is quite doubtful, however, whether it is proper to regard these bodies as spores. There is no good evidence that they have any special resisting power to heat like endogenous spores, and bacteriologists in general are inclined to regard them simply as resting cells.
I saw you take the sputa of a ague patient and demonstrate the spores and sporangia of the Gemiasma verdans. 3d. You said it was not common to find the full development in the urine of such cases, but only in the urine of the old severe cases. This was a mild case. 4th.
Some of the contents of the right nostril were blown on a slide, covered, and examined morphologically. Several oval bodies, round algae, were found with the characteristics of G. verdans and rubra. Also some colorless sporangia, and spores abundantly present. These were in addition to the normal morphological elements found in the excretions. Observation 27.
By JAMES H. SALISBURY, A.M., M.D. Mr. John Thomas. Panama fever. Vegetation in blood and colorless corpuscles. Spores in serum of blood adhering to fibrin filaments. Mr. Thomas has charge of the bridge building on the Tehuantepec Railroad. Went there about one year ago. Was taken down with the fever last October. Returned home in February last, all broken down.
Frond filamentous, inarticulate, cartilaginous, leathery, hollow, furnished at irregular distances with whorls or warts, or necklace shaped. Fructification: tufted, simple or branched, necklace shaped filaments attached to the inner surface of the tubular frond, and finally breaking up into elliptical spores. Aquatic. Batrachospermeae Plants filamentous, articulated, invested with gelatine.
In all spores were found and some sporangia, but they were not the genuine plants as far as I could judge. They were Protococcaceae. It is not necessary to add that there are no cases of intermittent fever regarded as originating on the localities named. Still, the ancient history of New England contains some accounts of ague occurring there, but they are not regarded as entirely authentic.
In my horror at the discovery, I had forgotten the broken package that had come to the hotel desk while we stood there. "Then it was Gavira who was receiving spores and cultures of the anaerobes!" I exclaimed, excitedly. "But that doesn't prove that it was he who used them," cautioned Craig, adding, "not yet, at least."
These are always a source of danger, even when the seed is treated with fungicides before sowing. "There are also chances for the infection of a crop if absolutely smut-free seed is employed. First, soil infection from a previous smutty crop; second, soil infection from wind-blown spores.
