Referemus etiam insolitam anni 1514 contagionem, quae in boves solum irrepsit, visa primo circa Foroiuliensem tractum, mox sensim et ad Euganeos delata, atque inde in agrum nostrum; abstinebat primo bos a cibo sine causa alia manifesta, spectantibus autem in ora eorum bubulcis, asperitas quaedam et parvae pustalae percipie­bantur in palato et ore toto; separare protenus infectum oportebat a reliquo armento, alioqui totum inficiebatur: paulatim labes illa descendebat in armos, et inde ad pedes ac quibus ea permutatio fiebat, sanabantur fere omnes, quibus autem non fiebat, plurima pars interibat. Harum ergo contagionum quae extrinsecus veniunt, potassima causa est aer, quanquam ex aquis et paludibus, et aliis nihil prohibet evenire.

Translation :

We recall an isolated contagious affection which occurred in cattle in 1514. It was first noted in the province of Frianl and later in the Euganean district, from which it spread to our parts (Verona). To begin with the cattle went completely off their feed without apparent cause until the herdsmen on opening the mouth saw that the palate and the whole of the interior of the mouth was affected with a certain rawness and small pustules. It was necessary to segregate those affected to prevent the infection of the rest of the herd. By degrees the lesions descended on the shoulders and spread to the feet. Those that showed these symptoms almost all recovered; those that did not perished. The main cause of this contagion, which came from without, was the air, although there was nothing to prevent it coming from water, marshes, or other sources.

Documents pour servir a l'Editlcation d'une Dermatologie Animale (Chien et Chat). By Ch. Leblois, Chef de Clinique a l'Ecole Nationale Veterinaire d'Alfort. Paris: Vigot Freres. 1926. Pages 156 with 29 figures. Price, 15 fr.

Although it is of comparatively small size, this deserves to be described as an original and valuable work. It is original for a work on the skin diseases of the domestic carnivora because the author has declined to follow beaten paths indicated by supposed analogies between human and animal diseases, which have often led to hasty and erroneous conclusions and thereby delayed the direct independent investigations necessary to put knowledge regarding diseases of animals on a secure basis. It is valuable on that account and also because the author has a style that enables him to impart the fruits of his experience in a way that is impressive and agreeable to the reader.

The title of the book is a little misleading, for it does not deal with ring­worm, except for the mention of a case in a cat imported from England. The parasite was proved to be the Microsporon felineum, and several persons with whom the cat had been in contact contracted the disease from it, although its fur appeared quite normal.

The first part describes the different forms presented by the lesions of cutaneous diseases, the terms to be applied to these, and their significance as signs of particular affections. The second part treats of the skin diseases of

the dog, and the third of those of the cat. A short final chapter deals with dermatology of the dog and cat from the point of view of jurisprudence.

As might have been expected, the largest amount of space is allotted to mange (sarcoptic and follicular) and eczema in the dog. Under the head of Otacariasis, caused by the Otodectes (or Chorioptes) cynotis, the author quotes from Nocard a description of symptoms in sporting dogs which appear to correspond exactly with those exhibited by dogs suffering from what at the moment is commonly called the "new disease" in this country. He adds, however, that such violent symptoms have hardly ever been observed in dogs at the Alfort Clinic, the usual history being simply that the dog scratches his ears.

This is a welcome addition to the literature on the subject with which it deals at a time when the diseases of the dog and cat are becoming increasingly important in veterinary practice. The first two chapters deal with the frequency of tuberculosis in the dog, and with its etiology and pathogenesis. These cover only the first ten pages, and the remaining three chapters deal respectively with lessions and symptoms, diagnosis, and treatment, all of which are described in a lucid and practical manner. There are fifteen text figures and two coloured plates.

In evidence of the growing importance of the disease it is mentioned that Petit and Germain estimated that in the years 1910-1913 13'5 per cent. of the dogs submitted to post-mortem examination at the Alfort Veterinary School were affected with tuberculosis.

In the chapter on etiology the author states that among some hundreds of cases in dogs he can remember only one that was probably of bovine origin, and he is emphatic in the view that in the immense majority of cases in Paris the disease is of human origin, the expectorate of consumptives being the most frequent vehicle of the infection. There is reason to believe that this rule does not apply to London, either with regard to dogs or cats, and further detailed research with regard to this point appears necessary.
