Those I now wish to place before the profession h ave been constructed with considerable care by Messr s. Arnold & S ons, whom I have to thank for the minute attention they h ave bestowed on their construction, and they are th e on es I recommend to be used in my Paper on Dentistry in th e 4th edition of Sir F. Fitzwygram's "Horses and Stables." Their a dvantages may be enumerated as follows : 1st. T he lightness of the " business," or operatin g end, r eadily allows of their use with one hand. 2nd. Their "lateral guards " offer sufficient guarantee against injury to the buccal membra ne, and assist t o r etain the rasp surface on the tooth operated on, difficulties I have more than once encountere d in operating with somewhat simila r rasps without them. 3 r d. The three rasp heads vary in their curves, in view of more r eady adjustme nt to varying conditions of abnormal g rowth.
The Veterinary journal. , 4th. The fact of the shafts fastening into the handle by a screw does away with the risk of a short head-piece becoming detached in the mouth, and possibly swallowed during the operation, which is liable to happen with the latter when the thread of the screw joint becomes loose from wear. The past ten or twelve years have witnessed a marvellous advance in knowledge of equine dental development, with its accompanying ailments, and many practitioners possess sufficient dexterity to manipulate and operate on the molars, even to the 5th or 6th, without balling-iron or other restraint, though few, I think, will dis pute their need for complicated cases; as we all know keeping the horse's jaws from closing during manipulation is a matter of skill, the r esult of practice combined, as it always must be, with unfailing patience. Few branches of our profession are more interesting than Dentistry, and none offer so sure a prospect of substantial pecuniary reward as does this one to the specialist, who establishes himself at one or other of our great racing centres. It would be idle, in addressing professional men, to dwell on the vast advantage of the modern system of individual treatment of molars, compared with the collective practice of the past. THE ACUTE EPIZOOTIC AND EPIDEMIC OUTBREAK OF HYDROPHOBIA AT MADEIRA. BY DR. JULIUS GOLDSCHMIDT, MADEIRA.
THE successive occurrence, both epizootic and epidemic, of hydrophobia in a country where it had been hitherto unknown, causes the history of recent occurrences at Madeira to he of great interest to the epidemiologist. The number of dogs in Madeira has always been large. There is no official statement on the point, but I may be entitled, having been a resident physician on the island for over twenty-seven years, and having therefore become extremely familiar with the place and its inhabitants, to make an estimate. In doing so, I am sure that I remain below the truth in putting the figure at one dog to two households (logos) each of six individuals-z~e., practically 11,000 dogs to 130,000 p ersons. The figures are less surprising if it is remembered that similar statistics for Europe indicate on an average one dog to sixteen inhabitants. There is only one town in Madeira-viz., the capital, Funchal, with 30,000 inhabitants; the rest of the population
