A Treatise on the Foot-rot in Sheep ,- including Memarks on the 

 exciti7ig Cause, Method of Cure, and Meajis of Preventing that 

 destructive Malady : — beirig the Substance of Three Lectures, 

 delivered in the Theatre of the Royal Dublin Society. By 

 Thomas Peall, Esq. Veterinary Professor to the Society. 

 Dublin : printed by .Toshua Porter, Grafton-street. 

 This is not only a scientific but (what all scientific books are 

 not) a highly useful and practical work. Mr. Peall opens with 

 a minute investigation of the structiu'e of the sheep's foot. If 

 in the course of his remarks Mr. P. should express himself in 

 strong terms on " the mass of absurdity and error," the " pre- 

 posterous reasoning," &c. which have been poured forth on 

 this subject, we can scarcely wonder ; knowing, as we do, the 

 great ignorance that pi'evails as to the commencement of the 

 disease, and being well aware, with Mr. P., that it is seldom at- 

 tempted to be cm"ed until it has attained even to suppuration. 

 But of all the errors which have been promulgated on the ques- 

 tion of foot-rot, from the Encyclopcedia Britannica downwards, 

 none strikes us as so absurd, so extraordinary, as those which 

 obtamed respecting that " very remarkable gland, or ratlier 

 glandular sac, which is found situated at the lower surface oi', 

 and between, the bones which articulate with the foot bones," 

 This little opening or duct (to be seen between the claws Cx 

 every sheep) has been by divers authors supposed to be t.^s 

 disease, occasioned by a certain worm, which has not inserted 

 itself into the foot by means of, but, as they infer, actually form- 

 ed, this opening ; and particular instructions are given in divers 

 works how to extract the worm. From Mr. Peall, the reader 

 will learn (and it is not the least important part of his book) 

 the use and importance of this organ ; which, so far from heir.g 

 what it has been ignorantly supposed to be, is, says he, " one 

 of the most singular apparatuses that I have ever met with f^r 

 preventing friction between the parts where it is situated."
