to push a blunt seton-needle, or eyed 
probe, from one opening to the other, 
armed with the tape, which should 
be daily smeared with mild blistering 
ointment, or common turpentine. In 
this way, report says, the College 
practice has proved very successful, 
and therefore merits trial. Blister- 
ing I have, however, found, when 
repeated over and over, and particu- 
larly when mild intermediate stimu- 
lants have been kept applied, as a 
weak ointment of Spanish flies, or oil 
and turpentine, &c., has commonly 
proved equal to all the benefit these 
obstinate cases can receive ; for when 
the bony deposit is fully formed, it is 
in vain to expect its entire absorp- 
tion : even its partial absorption is 
often frustrated. Our principal hope 
lies in removing that inflammation 
which is the existing cause of much 
of the pain, stiffness, and tumefaction 
in the ligaments around, and likewise 
in preventing the increase of the 
bony deposit. Our hopes of success 
must also greatly depend on the time 
of the existence of the evil. When 
it is early attended to, before the 
bony deposit has gained its full 
solidity, stimulants act more favor- 
ably, and lessen it more materially. 
It remains to add, that, when re- 
peated blistering fails, the more active 
method of promoting absorption by 
firing may be tried, carefully avoiding 
to fire too actively or deeply, other- 
wise the integuments may be pene- 
trated, and a dangerous inflammation 
and sloughing of tiie ligaments follow.”

The extracts we are about to quote from the “Preface,” 
will explain the origin of the publication of these “ Lectures.” 
<c The following pages contain merely the substance of two 
lectures delivered by the author before the Royal Agricultural 
Society, on the 17 th, and 24th, May, in the present year.” 
The subject was not new to the author, and observations upon 
it had convinced him, that the opinions of veterinary writers, 
both English and French, were often incorrect. Above 2,000 
animals had been examined by him, whose ages were cor- 
rectly known. 
“ The development of the teeth of the Ox, Sheep, and 
Pig,” forms a subject which, though not altogether an unex- 
plored field of science, is one which has been so imperfectly
