SUMMARY OF CURRENT RESEARCHES RELATING TO 
This bacillus is said by the author to possess considerable affinities with 
Bacillus cholerse gallinarum, B. typhi ahdominalis, B. neapolitaniis, and 
Bacterium coli commune^ but is distinguishable therefrom by the size of 
the individual or the size, shape, or colour of the colonies, and is to be 
regarded as a pathogenic microphyte capable of exciting inflammation 
of the intestine. 
No name is proposed for the micro-organism, and no experiments on 
living animals with pure cultivations were made. 
In addition to the foregoing, the author also isolated a bacillus 
which is identical with Bacillus malarise. 
Fraenkel and Pfeiffer’s Microphotographic Atlas of Bacteriology.* 
— Drs. Fraenkel and Pfeifler have just issued the fourth instalment of 
the Atlas of Bacteriology. This part deals with the bacillus of anthrax, 
and six plates, accompanied by explanatory text, are given. 
Bacteria and Disease.! — The following provisional table is intended 
to show the present status of bacteriological investigation with reference 
to the causation of some of the more important diseases. 
(1) Diseases ivhose bacterial cause is determined with comparative cer- 
tainty : — Anthrax, caused by Bacillus anthracis. Aphtha, caused by 
Oidium albicans. Cholera, caused by comma bacillus. Erysipelas, 
caused by Streptococcus erysipelatosus. Gonorrhoea, caused by the gono- 
coccus. Leprosy, caused by the lepra bacillus. Malarial fever, caused 
by Bacillus malarise. Meningitis (epidemic, cerebro-spinal), caused by 
Diplococcus lanceolatus. Pertussis, caused by a bacillus. Pneumonia, 
caused by Diplococcus pneimonise. Purpura, caused by Monas hsemor- 
rliagica. Pyaemia, caused by Streptococcus pyogenes. Eelapsing fever, 
caused by a spirillum. Tetanus, caused by a “ pin-head ” bacillus. 
Tuberculosis, caused by the tubercle bacillus. Typhoid fever, caused 
by Bacillus typhosus. Typhus fever, caused by a bacillus. 
(2) Diseases probably bacterial, but whose exciting cause has not been 
certainly determined : — Carcinoma, dengue, diphtheria, dysentery, gan- 
grene, glanders, measles, parotitis, rabies, rheumatism, rotheln, scarlatina, 
syphilis, yellow fever. 
It is probable that all catarrhal diseases, such as bronchitis, con- 
junctivitis, diarrhoea, &c., are of bacterial origin, and that various 
bacteria are engaged as causative factors in different varieties of these 
several diseases. These have been isolated with varying degrees of 
certainty. 
With regard to diphtheria, it is probable that two or more diseases 
are included under this name, and that more than one bacterium is 
capable of inducing the formation of pseudo-membrane.
