consequence of the diminished price of wool. It is said that 
wool is nearly fifty per cent, cheaper than it was four years 
since. 
SCAB IN SHEEP. 
During the past month several seizures have been made 
in country markets of sheep affected with scab, which would 
seem to show that this disease is very widely spread. Con¬ 
victions for exposure of the sheep for sale have followed in 
these cases. In one instance a farmer in Lancashire has 
been fined for not giving notice of the existence of the disease 
in his flock. On the Continent the disease continues to pre¬ 
vail in many cases, and particularly in the district around 
Stettin. 
TYPHUS IN PIGS. 
This disease has manifested itself in three or four counties 
during the last month. We have received reports of its ap- 
]iearance in Middlesex, Berkshire, Huntingdonshire, and 
Norfolk, in a form so virulent as to destroy the animals attacked 
in the course of twenty-four to thirty-six hours. In most of 
these cases the remaining animals of the herd have been slaimh- 
tered; the healthy being sent into the dead meat market. 
Facts and Observations. 
Cohesion of the Blood-Corpuscles. —As to this 
singular phenomenon, Professor Norris, of Birmingham, 
gives the following account in a paper quite recently com¬ 
municated to the Royal Society. My idea of the blood- 
corpuscle is that its contents are something essentially dif¬ 
ferent, so far as cohesive attraction is concerned, from the 
liquor sanguinis, that is to say, not readily miscible with 
liquor sanguinis. This is, of course, self-evident, if, accord¬ 
ing to some modern views, we regard the corpuscles ^as tiny 
lumps of a uniformly viscous matter,^ inasmuch as such 
matter must be insoluble in, and immiscible with, the liquor 
sanguinis. The explanation is equally easy, if we accept the 
old and, I believe, the true view of the vesicular character of 
these bodies, as we have only to assume that the envelope is 
so saturated with the corpuscular contents as practically to
