properties it possesses. It is practically little more than sulphate of soda, 
and its value to you, as a manure, would not be 10s. a ton. In fact, I 
would prefer not to use it at all. 
Mr. Taylor only purchased 6 cwt. on trial. 
6. Mr. Henry Pye, of St. Mary’s Hall, near Rochester, sent, on 
June 25, for analysis, a sample of what had been offered to him by 
a local dealer as “ Guano,” and costing 71. a ton. It was recom- 
mended as a manure for hops. 
Mr. Pye, before purchasing, sent a sample for analysis to Dr. 
Yoelcker, and received the following report : —

This ought not to be called Guano. It is nothing more than sea sand, 
shells, &c., with a little fish hone. 
The worth of such a manure as the above would not be more 
than 21. a ton, instead of the 7/. a ton charged.

LOUPING-ILL IN SHEEP. 
The investigations recorded in this article were undertaken at 
the desire of the Veterinary Committee of the Royal Agricultural 
Society, in order to obtain information regarding the cause of the 
disease termed louping-ill. The investigations were begun in the 
month of May 1893, in the county of Northumberland, on farms 
situated in the North Tyne district. I take this opportunity of 
expressing my indebtedness to gentlemen in the district— and par- 
ticularly to Mr. John Robson, of Newton, and Mr. Hedley, Whick- 
hope — who lent valuable assistance in the inquiry, both by communi- 
cating information gained from their own experience of the disease 
and by procuring cases from the adjoining farms. 
The plan of the inquiry was as follows : — 
1. To study the symptoms in the living subject. 
2. To make a careful postmortem examination of each case 
obtainable. 
To make inoculation experiments to test the transmissibility 
of the disease. 
It was rather unfortunate, in one sense, that the disease at the
