exhibitor having butter and cheese made daily before the public 
on Mr. Swartz's method. 
The total cost of the Exhibition, exclusive of the value of the 
prizes, amounted to 52,986 marks, or nearly 2650/. ; and the 
receipts from all sources came to 42,229 marks, or 2110/. ; 
leaving a deficit of 540/. Of this sum, 500/. was covered by 
the surplus of an Agricultural Exhibition held in 1863, which 
had been placed at the disposal of the Executive Committee of 
the Dairy Show, and the remainder was subscribed by the mem- 
bers of the committee, so that the guarantors were not called 
upon to contribute. 
The holding of the Exhibition was made the occasion of lec- 
tures in the afternoons and banquets in the evenings ; and the 
hospitality and kindness of the German people were never more 
conspicuous. The officers of the Exhibition earned the warmest 
thanks of all the delegates, and more particularly of those who 
attended as representatives of the English Societies. Several ot 
these gentlemen I knew or had corresponded with before, and 
nothing could be more cordial than their reception of me, both 
personally and officially ; while, in addition to the increased 
knowledge of dairy-farming which the Exhibition enabled me 
to acquire, I have the most pleasing reminiscence of the many 
new friendships which I formed on the occasion. 
XXIII. — Further Notes of Experiments at the Brown Institution 
on the Communication of Foot- and- Mouth Disease from Diseased 
to Healthy Animals. By W. DuGUID, M.R.C.V.S., Veterinary 
Surgeon to the Institution. 
In a Report already published in the ' Journal of the Royal 
Agricultural Society,' * Dr. Sanderson gave an account of some 
preliminary experiments on foot-and-mouth disease, which ap- 
peared to show that under certain circumstances its communica- 
tion by mediate contagion is more difficult than is usually 
supposed. In the experiments in question, the infecting material 
was obtained at Deptford, either from live animals or (in one 
case) from an animal just slaughtered. In all these cases, the 
appearances of the disease were so characteristic that, although 
nothing was known of the previous history of the cases, no 
doubt could be entertained of their nature. 
Opportunities have since offered themselves for repeating the
