The accompanying illustration shows how these bacteria appear under the microscope; the drawing was made from fluid taken from the spinal canal of a patient suffering from cerebrospinal meningitis. These germs get within the skull and spinal canal, and produce violent inflammation of the coverings of the brain and cord; these membranes are called "meninges," hence the name "cerebrospinal meningitis." Within a short time after their entrance pus is produced, and the condition becomes practically one of abscess around the brain and spinal cord. In almost all cases the disease is preceded by a slight catarrhal condition of the nose and throat, the symptoms being those of an ordinary cold. The symptoms that point to the covering of the brain being attacked come on with great suddenness; there is usually a chill, followed by intense headache, vomiting, restlessness, with great dread of noises and bright light; in many cases reddish spots appear beneath the skin, and these are usually tender on pressure. In some cases the muscles of the neck become very stiff, and contract so that the head is drawn backward. The temperature is somewhat irregular, but is always above normal in the beginning, and sometimes goes very high; the pulse as a rule is normal, or but little accelerated. After the patient remains in this condition for a period varying from a few hours to several days, he generally becomes unconscious, and in a comparatively short time dies. In some cases the symptoms after starting off very violently quickly subside, and the patient makes a comparatively rapid recovery. In other instances the disease begins more mildly, the patient having more or less of the usual symptoms, but not so severely as is ordinarily the case; in such cases the patient may die, after lingering weeks or months; or may make a protracted recovery, frequently with partial paralytic conditions that permanently remain. Unfortunately we possess no specific for this disease. Recently there has come into vogue a treatment by a serum supposed to have antitoxic power against this disease, but its exact value is, as yet, by no means settled; it must be used early if any good is to be expected from it. In addition to the antitoxin all that can be done is to keep the patient quiet with anodynes, and to minister to his comfort in every way possible. Ice applications to the head sometimes alleviate the intense headache. As the disease is practically an abscess around the brain and cord, perhaps the most rational treatment would be to open up the skull and let the pus drain away.
