appeared normal, except for distention of veins: a small amount of 
bloody serum was found in one lateral ventricle, the blood probably 
coming from a cut vein; on section the cerebrum appeared about nor- 
mal: basal ganglia on section appeared normal: section of pons and 
cerebellum showed nothing abnormal. 
The meninges over the occipital lobe of case 91 were congested i hypostatic), but 
otherwise normal; in case 107 the meninges were normal, except a shght congestion 
(hypostatic ) in the vessels of the pia over the occipital lobe; there was no e^ndence 
of meningitis Wilson and Chowning, 1903a. pp. 52, 4S i. 
In case 11 (1901) the dura showed outer surface injected, but other- 
wise normal: removal of dura showed some adhesions at the vertex 
between the membranes and the brain substance, the area of adhesions 
being small. 
In case 91 there was no inflammation or marked congestion in either of the menin- 
ges of medulla and cord; in case 107 there was no inflammation of the upper 6 
inches of medulla and cord t Wilson and Chowning, 1903a, pp. IS— 19, 53). 
In case 11 (1901) section of the medulla showed nothing abnormal: 
the spinal cord showed considerable injection of the vessels, probably 
hypostatic: no lymph exudation or other evidence of inflammation 
was present: dura was normal: cross sections of cord at 1-inch inter- 
vals showed nothing abnormal: 15 cc. of clear spinal fluid was aspi- 
rated through the lumbar region before the canal was cut open. 
Doctor Alton says that case 13 may possibly have been a case of 
meningeal irritation following measles, or may have been due to tick 
bite and infection from that source (no autopsy). 
Local physicians have repeatedly spoken of the resemblance of 
*■ spotted fever” to cerebrospinal meningitis, and. in fact, the resem- 
blance in some cases is verv striking. Although the central nervous 
system has been examined upon autopsy in only a few cases, still it 
would seem rather remarkable that none of these autopsies showed 
the pathological lesions in case this disease were actually meningitis. 
At present, therefore, we are not justified in concluding that the 
"'spotted fever” under discussion is cerebrospinal meningitis 
ConPAEisox. — In Texas fever no nervous lesions were found which can be regarded 
in any sense as pecuhar to or characteristic of the disease. It may be said, in gen- 
eral, that the bi’ain share<I the general tendency toward the injection of the capillary 
system. The vessels of the pia and the plexuses were engorge^I, and over the frontal 
lobes and near the great transverse Assure it was more or less pigmented — a condition 
also met with in other diseases. The gray matter of the cerebmm and especially of 
the cerebellum appeared of a more pinkish color. The white substance was normal 
in color, the ventricles free from fluid ( Smith and Kilborne, 1893, pp. 2-5-26 >. 
In canine piroplasmosis a shght congestion of the memnges is found in some cases. 
KZEXIG’S SIGX. 
Kemig's sign is absent (Wilson and Chowning, 1902a. p. 133: 1903a, pp. 49. -50, 57; 
1904a, j). 38 ) .
