37. _Erysipelatous Mumps or Angina Parotidiana._--Dr. BEHR of Bernberg, has published in the _Journ. der Pract. Heilkund for July_, 1825, an account of this disease, which we find in the _Bulletin_ for Feb. 1826. Dr. BEHR'S "memoir is intended to pourtray the principal features of an epidemic prevalence of parotitis at Bernberg, in the months of December, 1822, and January and February, 1823. Dr. B. attributes it to the frequent and sudden variations of the atmosphere at that period." He says, "the disease is so rare in this country, that physicians of 30 years standing had never met with it before." Bernberg contains 6000 souls; it is divided into two parts by the Saale, and it is situated on the great road from Leipsic to Magdeburg, in a narrow valley, which runs from N. W. to S. E. The precursory symptoms were rigors followed by heat, heaviness of the limbs, pains in the joints, especially in the evening, sense of tension in the region of the lower jaw, and sometimes a difficulty in mastication. The appetite was usually natural, with gastric symptoms only in the most severe cases. On the evening of the 3d day, there was an increase of uneasiness with chills and heat, after which the patient commonly enjoyed sweet sleep. The next day, on awaking, he felt tolerably well, and had no more sense of heaviness in his limbs, but his face was swelled on one or both sides. Speech and mastication were effected with difficulty; the lower jaw was _comme engourdie_, and a dull pain was felt in the ligaments of the joints; the tumefaction increased and soon extended from the ear to the cheek. On a careful examination, it was found to affect the parotid gland, and the surrounding cellular tissue. The tumour was hard, diffused, and not very painful, except on pressure. The colour and temperature of the swollen part were natural. In the evening, the pulse became hard and accelerated, the tongue white, the stools more consistent than common, and the urine pale. The following night he was agitated, frequently awakened by lancinating pains in the affected part, and sometimes by a sense of tension in the head. The following day, the tumour reached its maximum of elevation, and sometimes comprised the submaxillary glands of the same side. From this time, the pains did not increase, and the skin became slightly red only in a very few examples.
