_MENTAL AUTOMATISM._

A recent work by Prof. Th. Flournoy, entitled ‘Des Indes à la

Planète Mars,’[G] contains an account of a remarkable case of mental

automatism, or sub-conscious personality. The subject is a young woman

of about thirty years, apparently in good health, but always of a

nervous and imaginative type. She developed tendencies towards lapses

of consciousness, hallucinations and automatic actions; and these

developed later, under the inspiration of spiritualistic séances, into

a series of cycles, or automatic dramas, in which the medium speaks

or writes and acts under the influence of several diverse subordinate

personalities. In one of these cycles--which, it must be understood,

are continued from one sitting to another, although in her intermediate

normal life she knows nothing of what she has said or done in the

trance--she becomes Marie Antoinette, and is said to act the part

with unusual dramatic skill. In another and far more elaborate cycle

the scene is transferred to the planet Mars, and the houses, scenery,

plants and animals, peoples, customs and goings-on of the planet are

described; sketches are made, and reproduced in the volume, of these

extra-mundane appearances. Still more remarkable is the appearance of

the Martian language, which in successive séances the subject hears,

speaks, sees before her in space, and, in the end, even writes. From

the mystery of Mars we are taken to the equally mysterious Hindu cycle;

here the medium becomes an Indian princess of the fifteenth century,

reveals her history and that of her associates in the Oriental life,

tells of herself as Simandini; of Sivrouka, her prince, who reigned

over Kanara and built in 1401 the fortress of Tschandraguiri. Wonderful

to relate, these names are not fictitious, but are mentioned by one De

Marlès in a volume published in 1828; the author, however, does not

enjoy a high reputation as a historian. When occasional utterances

of the Hindu princess are taken down, they are found in part to have

close resemblance to Sanskrit words; while in her normal condition the

medium is as ignorant of Sanskrit as she is of any language except

French, and is entirely ignorant of both De Marlès and the people

of India five hundred years ago. Surely this is a tale, bristling

with mystery and improbability, which, if told carelessly or with a

purpose, we should dismiss as a willful invention! M. Flournoy has been

unusually successful in revealing the starting points of the several

automatisms and of connecting them with intelligible developments of

the medium’s mental life; and the manifestations, though they remain

as remarkable examples of unconscious memory and elaboration of ideas,

nowhere transcend these limitations. The sketches of Martian scenery

are clearly Japanesque or vaguely Oriental; the Martian language is

pronounced an ‘infantile’ production, and is clearly modeled after the

French, the characters being the result of an attempt to make them as

oddly different from our own as possible; the Sanskrit goes no farther

than what one could get from a slight acquaintance with a Sanskrit

grammar; and while there is a copy of De Marlès in the Geneva Library

(where the medium lives), no connection can be established between

either De Marlès or the grammar and the subject of this study. Most

of this knowledge of these remarkable sub-conscious states would have

been impossible were it not for ‘spirit control’ of one Leopold, who,

in accordance with the doctrine of reincarnation which permeates the

several cycles, was in his life the famous Cagliostro. By suitable

suggestion, Leopold can be induced to make the entranced subject speak,

write, draw, or interpret her strange messages from other worlds; and

where Leopold says ‘nay’ all progress is stopped. This case has many

analogies with other cases that have been recorded, but goes beyond

most of them in the complexity and bizarre character of the unconscious

elaborations and in the feats of memory and creative imagination which

it entails. These accomplishments, it should be well understood, never

appeared suddenly or fully developed, but only after a considerable

period of subliminal preparation, and then only hesitatingly, and

little by little, just as is the case with the acquisitions of normal

consciousness; and all these acquisitions bear unmistakable marks of

belonging to the same person. The special value of this account thus

lies in the accuracy of the description and the success with which the

account has been made thoroughly intelligible and significant.

English version, under the title ‘She Lived in Mars.’

_THE MOSQUITOES OF THE UNITED STATES._

Dr. L. O. Howard, the entomologist of the United States Department of

Agriculture, has just published a bulletin entitled, “Notes on the

Mosquitoes of the United States: Giving some Account of their Structure

and Biology, with Remarks on Remedies.” The author has, for some years,

been interested in the general subject of the biology of mosquitoes

and of remedies to be used against them, and has brought together in

this bulletin all the published and unpublished notes which he has been

collecting during this period. The bulletin contains synoptic tables

of all North American mosquitoes, prepared by Mr. D. W. Coquillett,

and gives detailed facts regarding the geographical distribution of

the different species mentioned. All the five North American genera

are illustrated and full, illustrated accounts are given of the life

history of the two principal genera, Culex and Anopheles, as studied

in _Culex pungens_ and _Anopheles quadrimaculatus_. The author calls

special attention to the two genera of large mosquitoes, Psorophora and

Megarhinus, and urges the importance of the study of these two genera,

especially by physicians in the South, in regard to their possible

relation to the spread of malaria. Considerable space is given to the

subject of remedies, the principal ones considered being kerosene

on breeding pools, the introduction of fish in fishless ponds, the

artificial agitation of water and general community work. It is clearly

shown not only that the mosquito may be, in many localities, readily

done away with at comparatively slight expense, but that by careful

work many malarious localities may be made healthy. The subject of

mosquitoes and malaria is not discussed in the bulletin, which contains

simply references to available papers on this subject, like the article

by Dr. Patrick Manson, published in THE POPULAR SCIENCE MONTHLY for

July, the aim of the author being to bring together all available

facts about the mosquitoes of the United States, in order to assist

physicians who are studying the malarial relation from the point of

view of local conditions.
