and upwards. 
From this it would appear that two persons in every seven of 
those who are of independent means keep a riding or carriage 
horse. 
The increase and decrease in the number of carriages and horses 
within the last ten years is a remarkable sign of the times. Since 
1840 the number of all kinds of horses throughout Great Britain 
has decreased 43,000. But while some have declined, others have 
increased in number. Of private riding and carriage horses (where 
one only is kept) there has been a decrease of 12,000, and of 
ponies 700. Stage-coach horses have declined 4000; post horses 
2500 ; horses used in husbandry, 57,000 ; breeding mares, 1300; 
colts, 7000 ; and horses kept for sale, 500. The London hackney- 
coach horses, on the other hand, have increased in the same space 
of time no less than 2000, and so have the draught horses used in 
trade to the extent of 17,000; while those kept by small farmers 
are 13,000 more, and the race-horses 400 more than thev were in 
1840.

Inoculation by Means of the Insect . — (Performed on the sheep 
Nos. 1 and 2.) — Is* day. On the 7th of October, at nine o’clock 
in the forenoon, I inoculated these two sheep in the following 
manner. A lock of wool was pulled off from the middle of the 
back, so that a naked spot, 4-10ths of an inch broad and 8-10ths 
of an inch long, was formed, and upon this spot another lock of 
wool taken from the neck of another very scabby sheep was laid,
