xlii JoURNAL OF COMPARATIVE NEUROLOGY. 
The second part consists in reality of an introduction, emphasing 
the importance of heredity (especially for the ‘‘degenerative types of 
insanity”) and of vascular derangement; the gross: pathological anat- 
omy and the ‘‘special pathology,” dealing with the nerve-cell ; and fur- 
ther, the ‘‘pathology of the cerebral arteries and veins” and ‘‘syphil- 
itic vascular lesions.” 
The clinical section (part ITI) gives a sketch of classification (4 p.), 
the general etiology of insanity (pp. 101-108), general symptomatology 
(pp. 109-124) and general treatment (pp. 125-129). 
The very plan of this general preparation of student and practi- 
tioner for the problems of the special clinical portion is open to several 
criticisms. 1. We may well plead for the busy practitioner, that he 
shall not be burdened with things which are of no avail to him or to 
psychiatry as it stands today. What interests a writer of a text-book 
on psychiatry need not belong to the psychiatry nor to the range of 
interests of the practitioner. From this point of view the greater por- 
tion of parts I and II are written pro domo, or for the students working 
in special laboratories. For the latter the scope of thesé parts is, how- 
ever, too small and not systematic enough; and for him who knows 
little of laboratory work—practitioners so numerous that we cannot 
eliminate them—they are to some extent misleading and unintelligible. 
2. The limitation of the writer’s considerations to the cortex 
cerebri is arbitrary. We maintain that as far as we know anything 
about the nervous system in ‘‘mental diseases,’’ we have not one on 
record which limits itself to the cerebral cortex, if it gives any lesions 
at all. If the cerebral cortex receives special attention, it ought not to 
be treated as one homogeneous thing, in these days of CajaL and 
FLEcuHsIG and others, nor should one meet with descriptions of ‘‘the” 
nerve-cell. 
3. In point of illustration and description and clearness the vas- 
cular disorders obtain an undue predominence; the few cases of pig- 
mented and shrunken cells (plate V) are in remarkable contrast with 
the plate on vascular changes and the figures of the basal blood vessels 
and the cells in ricin-poisoning. Are we to be blamed for having ex- 
pected some illustrative evidence of BERKLEy’s types of cell degenera- 
tion (such as depigmentation) ? 
We do not want to leave this cortical part of psychiatry without a 
tribute to the presentation of the problem of cerebral circulation and 
the digest of much of BERKLEY’s own work. We repeat, however, 
that to our own mind the question, What does a student of psychiatry
