one minute of general conversation the subject was asked to repeat the words. Immediately after this three numbers, such as 3-88116, were given and recalled after one minute of distraction, as before.

Sex.-There was practically no difference in the results in the two sexes. 20% of the males and 21% of the females recalled both sets correctly; 33% of the males and 32% of the females failed to recall either; 46% of the males and 46% of the females recalled one set correctly, but failed to recall the other.

Form of Disease.-There were six catatonic males and nine females, seven hebephrenic males and ten females and two paranoid males and nine females. In tabular form the results are as

As seen above in the catatonic form, 33% of the males recalled both correctly; 16% failed on both and 50% recalled the first correctly, but failed on the second. Of the females, 11% recalled both correctly, 44.4% failed on both and 44.4% recalled one correctly. 14% of the hebephrenic males recalled both correctly, 29% recalled both incorrectly and 57% recalled one correctly, while 20% of the females recalled both correctly, 40% recalled both incorrectly and 40% recalled one correctly. Both paranoid males failed to recall either set, while 33% of the women recalled both correctly, 12% both incorrectly and 55% recalled one correctly.

Age. The ages of the patients varied from 15 to 50, seven being over 40 years of age and 5 under 20. The results show that 20% of the males under 25 recalled both correctly and 50% recalled one correctly, while of the females 50% recalled one correctly, but none recalled both.

Dementia.-The degree of dementia must necessarily be determined in an arbitrary fashion. The subjects were divided into two groups, one showing slight dementia, among which were included the acute cases and the chronic cases showing slightly marked apathy, indifference and only slight judgment defects; while those showing a more marked apathy, many judgment defects, and were of a long duration were put in the group of marked dementias. Nine males and 15 females showed slight dementia and 6 males and 13 females were markedly demented. In those showing slight dementia there was practically no difference between the males and females.

In those showing marked dementia the males gave 66% incorrectly, 16.6% gave one correctly and 16.6% gave both correctly, while of the females, 30% answered both correctly, 23% answered one correctly and 46.1% gave both incorrectly.

Duration of the Disease.-In seven females and six males the duration was less than one year; of these, two females gave both correctly and five gave one incorrectly, while two males gave both incorrectly, and four gave one incorrectly. Ten females and eight males had been suffering with the disease from one to five years. Of these, three males and one female answered both correctly, two males and five females recalled both incorrectly and three males and four females recalled one correctly. There were 12

patients with a duration of from five to ten years. Of these three females recalled both correctly, four females and one male recalled both incorrectly and four females recalled one group correctly, but failed to recall the other.

In the second group a series of pictures were shown for 30 seconds; these were then covered and the subject asked to name all the objects seen. This was repeated three days in succession, the same pictures being shown, and the results tabulated as in the first group. There were 14 objects or groups of objects and the subject was asked to name the object and not go into details about the color, etc. The work was done in a room off the ward, and the patients admitted one at a time. Among the younger patients there was some rivalry as to who could recall the larger number, but only one man succeeded in naming all on the page, and he added three objects which were not there. Many of the demented patients would name all they could in 20 or 30 seconds, and if urged to continue would almost invariably fabricate and name various objects which were not on the paper, and objects which could not be well called up by any association with objects which were on the paper. For example one patient when asked to continue said train robber, another horse and buggy, etc. In this group there were 43 subjects, 29 male and 14 female. Several others were tried, but after naming one or two objects would stop and express their delusions or would refuse to continue. This refusal was especially marked among the women. Ten normal men and ten normal women were first tried with the pictures once. The men averaged 73.7% correct and the women 60.31%, while the time occupied by the men in relating the subjects was 114.5 seconds, and the women 64 seconds.

The results were tabulated according to the percentage of correct answers in the first, second and third attempts, the number of incorrect answers referring particularly to objects which were not on the paper, and also the time for each attempt.

Form of Disease.-There were ten males and five females suffering with the hebephrenic type of disease. The accuracy of the male replies increased from 31.4% correct on the first trial to 50.7% on the second and 63.57% on the third. The females recalled 32.85% correctly on the first trial, 46.42% on the second and 46.42% on the third trial. The incorrect replies of the males increased from 5 on the first to 12 on the second and 16 on the third trial, while the females gave 7 incorrect replies on the first, 4 on the second and 7 on the third trial. Thus while with the males the percentage of correct replies increased, the incorrect replies also increased correspondingly, while with the females there was no such increase either in the correct or incorrect recollections. With the males the time increased from the first to the third trial, while with the females the time for the third trial was less than for either of the preceding.

There were 12 catatonic males and 4 females. In this group also the males made a better showing than did the females. Although the females made a higher percentage of correct replies on the third trial than did the males, the males showed a more marked increase from the first to the third trial. The males gave more incorrect replies than did the females. The time taken in telling what they had seen was longer in this group, as a rule, than in the former, as seen by the table:

In the paranoid group there were seven males and five females. Although the males gave a larger total of correct replies the relative increase of the males and females is about the same. As in the two preceding groups the males gave a larger total of incorrect replies. The average of correct replies was greater in this group with both sexes than in either of the preceding and the relative increase was also greater. The time is also greater than in the former groups and increases proportionally to the increase of correct replies.

Degree of Dementia.-The degree of dementia was determined in this series as in the first. There were 7 females and 16 males in the slightly demented group and 7 females and 12 males with marked dementia. As would be expected, the percentage of correct replies was greater with those slightly demented than with those in whom deterioration was more marked and the time is increased with the greater percentage of correct replies. There is an increase in both groups from the first to the third trial, but this increase is more marked in those slightly deteriorated. The males of both groups gave a larger percentage of correct replies and also gave a larger total of incorrect replies. The results in tabular form are as follows:
