REVIEW— tVARIOLA OVINA. 
“ It was about a fortnight after the two flocks were pastured to- 
gether that the malady first shewed itself in the Downs, and these 
seemed to suffer more from it than the Merinos. The flocks were 
now separated ; still the disease continued to advance, and daily 
losses were sustained.

“ We have ascertained that the fifty-six Merino sheep purchased 
by Mr. Statham were brought by the ship ‘Trident’ from Ton- 
ningen, on the coast of Denmark. When disembarked they ap- 
peared to be in health, and were sold by the salesman to whom, 
with other sheep, they were consigned. We have not succeeded 
in tracing the subsequent distribution of each separate lot of this 
cargo, but we are assured that many of the animals still continue 
well. It is, therefore, evident that, in this particular instance, the 
malady was imported from Denmark, but this unfortunately did 
not prove to be a solitary case of its introduction. 
“ Within a day or two of the arrival of the ‘ Trident,’ the ‘Moun- 
taineer’ and the ‘ Princess Royal’ came into port, each vessel 
having on board a number of Merino sheep brought from Hamburgh. 
The whole number of sheep which arrived by the * Princess Royal’ 
was 507, and these were exported by three different persons in the 
following proportions: 216 by A.; 200 by B. ; and 91 by C.; so 
that the fact of some of these sheep having escaped the disease is 
easily accounted for, as they, in all probability, came from differ- 
ent localities, and were free, when exported, from small-pox in its 
incubative stage, and were not exposed to infected animals at a 
time when the disease was communicable. Some of the 507 sheep 
above referred to were sold to the butchers, and others to farmers 
as ‘ stock sheep :’ the latter were bought, in several quantities, on 
the 26th July, by Mr. B. Weall, of Woodhall, Pinner; Mr. Good- 
child, of Kingsbury; Mr. Pitman, of the same place; and Mr. 
Choke, of Barking : those purchased by the two last-named gen- 
tlemen are said to have continued in health ever since. Mr. Good- 
child’s sheep, however, shewed symptoms of the disease very 
shortly after arriving at his farm, their illness being attributed to 
his having had them dipped or washed, for its true nature was not 
suspected. That portion of the cargo of sheep of the ‘ Princess 
Royal’ which was purchased by Mr. Weall consisted of 80 Me- 
rinos ; and on the same day he bought 166 other sheep of the Me- 
rino breed that had arrived by the ‘ Mountaineer.’ These two lots 
were placed together, and, subsequently to being sent to Pinner, 
were equally divided between Mr. Weall and his brother. In each 
moiety the disease shewed itself, being first observed among the 
eighty sheep, about ten days after their purchase ; and from them 
it rapidly extended to the others. Out of those belonging to Mr.
