the power of setting up changes in the economy constituting 
disease; this property they may transmit to their progeny. 
3. That pathogenic Bacteria may be considered under three 
classes : 
(a) Bacteria of animal decomposition ; the activity of these 
varies in intensity at the various phases of their development. 
( b ) Bacteria of vegetable decomposition; perhaps Bacillus 
anthracis is one of these. 
(c) Bacteria which are true contagia, as the form producing 
pneumo-enteritis. There is evidence which proves that some 
other forms are carriers of contagion, and of them some may 
act simultaneously with the virus wfliich they convey. 
6. That there are various forms of blood disease due to 
Bacteria. The organisms act mechanically or directly on the 
blood, causing cohesion of blood-corpuscles and thrombosis ; also 
they may act directly as irritants on connective-tissue corpuscles 
and epithelial cells. 
On the evening of Tuesday, 23rd December, Dr. Greenfield 
exhibited a numerous and very excellent series of microscopic 
preparations, illustrating the course of lectures just delivered 
by him, in a highly satisfactory manner. The lesions of Cape 
fever, anthrax, septicaemia, and pyaemia, together with the 
Bacteria of these diseases, were well shown by means of stained 
specimens. The most choice objects were on view in the Lecture 
Theatre. Here we particularly remarked the flagellated organisms 
mentioned in the fourth lecture in connection with “ quarter 
evil,” most of the flagella being perceptible on careful scrutiny. 
Also the “ Bacillus from a farcy bud,” of which there were 
several slides. Bacillus anthracis under cultivation was 
most attractive. This attendance was numerous and highly 
appreciative, and the intellectual treat was not a little enhanced 
by the courteous manner in which the professor explained the 
various objects.

We shall now conclude our notice of the order Ranuncu-

genera: 
1. Chelidonium. Celandine. 
2. Corydalis. Fumitory, a form of,
