PLEURO-PNEUMONIA IN CATTLE.

minute, and, as said above, appear under the form of very 
slender threads, which may be wafted by the wind and 
carried to the young spikes of corn andgrass. The development 
of these bodies has not been observed. The first indication, 
however, of the disease is the presence of a thick, sweet, 
honey-like, colourless matter upon the spikes, which is filled 
with granules, resembling somewhat those of yeast; and it is 
supposed that the grain becomes ergoted in consequence of 
their presence. This was supposed by Quekett to be the, 
perfect fungus, and was called by him JLrgotetia abortifaciens 
the ergot being supposed to be merely a diseased condition 
of the grains induced by the fungus. The granules which 
appear at the upper part of the fungus must be distinguished. 
They differ in form, and probably have the function of im¬ 
pregnation, though this scarcely admits of proof. 
PLEURO-PNEUMONIA IN CATTLE IN AUSTRALIA. 
The following report on the lungs of diseased cattle re¬ 
cently destroyed at Campbellfield has been printed by order 
of the Legislative Assembly : 
Government Analytical Laboratory, 
Melbourne ; Jan. 29 , 1861 . 
In accordance with a communication, of date the 23d 
instant, received fromthe Hon. the Chief Secretary, instruct¬ 
ing us to examine certain diseased lungs of cattle recently 
destroyed for pleuro-pneumonia at Campbellfield, we have 
the honour to report as follows: 
The specimens submitted to us were five in number, and 
presented respectively the following general characters : 
1. Lungs of a calf—The upper half of the right lung was 
affected. Many of the bronchial tubes were filled with casts. 
Portions of this lung sunk in water. The pleura apparently 
unaffected. 
2. Lungs of a full-grown animal.—In one lung there was 
a large cavity, the contents of which had escaped during 
transmission. Other parts of the lung were quite solidified. 
3. Lungs of a full-grown animal.—Large portions of one 
lung, amounting to one half of the whole, solidified. The 
solidification extended from the anterior to the posterior 
surface. 
4. Lungs of a full-grown animal.—Pleural surface of one 
lung thickened to the extent of one inch. Substance of the 
lung completely disorganized at different parts. 
5. Lungs of a full-grown animal.—Presented the same
