Sequens considered the disease due to infection from a specific organism in the pus.

The herd consisted of 1200, and the teats were washed with carbolic solution 3 per cent., or corrosive sublimate i per 1000. He also painted the part over once a week with a mixture of creoline and gum, and by these means stamped it out.

MASTITIS IN THE BITCH.

Acute suppurative mammitis in the bitch is by no means uncommon shortly after parturition, and one or more glands may be involved. They become swollen, hard, tense, and painful, and the milk is changed into a purulent fluid, with great pain and high fever, the appetite being completely lost. The animal lies down constantly on her side, and takes no notice of surrounding objects. After the lapse of a very few days multiple abscesses form in the tissue of the gland, and point externally, leaving indolent ulcers and fistulae that heal up but slowly. Death from pyaemia may take place.—(Lucet, Leblanc.)

In one case observed by the author the first and second mammae on the left side were affected with abscesses, and in one reported by Lucet the second. He states that he found a white staphylococcus in the pus.^

After death lesions were discovered in the liver, spleen, and kidneys, from the fluid of which, on gelatine cultures, the same organism was isolated.

Lucet's observations are interesting, as it is probable that in what he terms adeno-fibromata, the Staphylococcus albus will be found, as it has been in the same neoplasm in the human being, and this is another argument in favour of the inflammatory nature of this condition in the domesticated animals. Gaucher and Surmont injected into the sinus of the bitch pure culture of the Staphylococcus albus from a case of chronic mammitis in the human being, causing subacute inflammation of the gland.

The author has studied the histological lesions of acute mammitis in the bitch, which are those of all acute inflammations. The epithelium is chiefly involved, the connective tissue being but very slightly infiltrated, and in the substance of the gland there are minute abscesses.

CHEONIC MASTITIS.

CHRONIC CATARRHAL MASTITIS IN THE COW. STREPTOCOCCIC MASTITIS.

Streptococcic mastitis assumes many forms ; it may be acute or chronic, sporadic or enzootic, and is known in France under the names of " mastitis of milking cows," " contagious mammitis," and " streptococcic mammitis." In Germany as " contagious catarrhal agalaxia " (Kitt), and in Switzerland as " gait " or " gelber gait.''

It is impossible to classify the observations on contagious mastitis published before those of Nocard and Mollereau, under the heading of streptococcic mastitis,^ but nevertheless these authors demonstrated that it was due to specific organisms, and opened the way for future bacteriological investigation.

In the same year Kitt in Germany published some experiments he had made, and in other countries various authors—viz. in Germany and Denmark, Bang,^ Switzerland
