his premises for some time past, and had induced him to get rid of nearly all 
his stock. 
Of the lot, 26 in number, so constituted, Mr. Berryman bought 22, namely, 
20 of the cattle which had been grazed by Mr. Wise, and tlie two Hull beasts' 
(marked by a scissors' clip) which had been on Mr. Taylor's farm for some 
days. The other four beasts of the lot of 26, namely, three of Mr. Wise's 
and one of Mr. Taylor's, were bought by Mr. Robinson in Hunmanby market 
on August 19th, and by him sold again directly to another dealer. 
These four cattle which were placed with a number of others were after- 
wards traced by Professor Simonds to a park near Leeds, and found to be in 
good health. 
The Hunmanby lot of 26 beasts being accounted for, the inquiry into the- 
origin of the malady at Pocklington may be continued. 
Suspicion at once pointed to Hull as the original centre of the outbreak. 
In the last week of July 18 Russian cattle affected with plague had stood on 
board the 'Joseph Soames' which was lying in the Humber dock so close tO' 
the quay that the Customs ofiScer, on one occasion, went on board without 
using a boat, merely stepping from one vessel to another. Communication of 
the infection to cattle in the town, by indirect means, might at least be- 
assumed as a probability ; and the concealment of the disease, the slaughter 
of the sick animals, and the exposure for sale in the market of the apparently 
healthy animals which had been herded with them, were circumstances 
which at once suggested themselves as simple and natural consequences of 
the first assumption. Three markets had been held at Hull between the 
time of the removal of the carcases of the plague-infected cattle from the 
'Joseph Soames' and the sale of the Hunmanby lot, and the serious question 
presented itself, " What has become of the cattle sold on July 29th, August 
5tb, and August 12th, in Hull market ? " 
No time was lost in prosecuting this' essential inquiry, in the conduct of 
which Mr. Shorten, Veterinary Inspector of the Port of Hull, rendered 
valuable assistance. Meanwhile the suspicion of an outbreak of cattle plague 
on Mr. Taylor's farm some considerable time prior to August 19th assumed 
the character of a [positive fact. First, it was a matter of observation that 
Mr. Taylor had got rid of nearly all his stock, and amongst other animals, he 
had sacrificed at a butcher's price a valuable heifer which had obtained several 
first prizes, and was expected to gain others. 
Next, Mr. Taylor admitted that he had reason to apprehend the existence of 
pleuro-pneumonia among his stock, and on that account considered it advisable 
to get rid of them. 
Thirdly, his valuable bull died on Wednesday, September 4th, after a short 
illness, and two cows which had been sent to this animal on August 31st, 
were seen by me to be suffering from cattle plague on September 9th. 
Under those circumstances I felt justified in assuming that the disease 
which Mr. Taylor suspected to be pleuro-pneumonia, was in reality cattle 
plague which he had introduced among his stock with cattle bought by him 
in Hull market on August 12th. The only difficulty opposed to this assump- 
tion was the length of time which had elapsed betw een the removal of the 
diseased Russian cattle from the 'Joseph Soames' on July 29th, and the 
purchase of the three animals by Mr. Taylor in Hull market on August 12th. 
This difficulty would of course have ceased to exist if the disease were dis- 
covered to have broken out among cows in the dairies of the town of Hull, 
because the presence of infected cattle in the market a fortnight after com- 
munication of infection from the Russian beasts, would have been easily 
explained. But the most careful inquiry failed to afford any reasonable 
ground for the conclusion that an outbreak of cattle plague had occurred ii> 
Hull.
