Kentucky Agric. Exp. Sta. of the State College of Kentucky 
for the year 1899, pp. 43-46, Frankfort, Ky., 1894.

the bacterial disease subsequently described more fully by 
Professor Pammel in 1895.

Said subsequently to have been based on a study of the 
black-rot, but this fact can not be determined from the abstract 
which is all that was ever published. Infections with pure 
cultures had not been obtained.

17-18, Sept. 10, pp. 478-486, 1 colored plate 
(showing signs and the character of the bac- 
terial growth on potato). 
This paper gives at length the reasons for the statements 
previ made in Science, and adds some new facts, the most 
important of which perhaps is that infections of the uninjured 
plant can take place by way of the water-pores.

parasitic organisms are disseminated. A 
lecture delivered before the Mass. Hort. Soc.,

1897. Boston, 1898. Also a separate. 
An abstract appeared in one of the Boston papers soon after 
the lecture, and there was also a separate of this abstract. 
1897. Stewart, F. C. The stem-rot of cabbage.

1897, vol. xx, No. 9, new series, p. 141. 
An editorial which includes, however, a letter from Mr. 
Stewart who says: ‘‘On Long Island there is a bacterial stem- 
rot of seed cabbage which is very destructive in some seasons." 
The distribution of the disease is attributed to infected seeds.

Mostly polemical but one additional fact is announced, t7z., 
that the ability of Pseudomonas campestris to liquefy gelatin 
depends on how the gelatin is made, and thus the apparent 
contradiction, in this particular, between Pammel’s results and 
those of the writer is explained.

This paper was not read at the Convention (see p. 86) and 
the MS. remained in the hands of the author for revision until 
Oct. 27, 1897. The Proceedings of which this forms a part, 
bears no date of issue but it was received from the binders and 
distributed by the U. S. Dept. of Agric., March 28, 1898. A 
brief synopsis of this paper appeared in the Exp. Sta. Record, 
1897-98, vol. 1x, p. 319.

This paper was sent to the printer the first of March, 1898, 
i. €., one year after the sending away of the Centralblatt paper 
of 1897 and after all of the leading statements in the latter 
paper had been experimentally re-examined by the writer and 
confirmed. The halftone from a photograph of part of a leaf 
(enlarged 24 times and made by transmitted light) probably 
gives as good an illustration of the foliar symptoms as can be 
obtained in black and white by use of photography.
