The very chronic one, sometimes follows such diseases as influenza, malarialand typhoid fevers, but there is no conclusive evidence that theyare the cause; the same is true of syphihs and trauma. The scleroticareas vary much in size, some being only microscopic and othersinvolving an entire lobe of the brain; the nodules may be scanty or numerous, often thelatter, and are irregu-larly distributed in bothbrain and spinal cord;they show no tendencyto follow tracts.
