[N. S. Vol. V. No. 110: 



Each member of the committee selected 

 a complete series of tests. The report in- 

 cludes these selections, together with brief 

 descriptions of methods. After each test and 

 method are placed the initials of the mem- 

 bers of the committee recommending it.* 



Preliminary Data, : B. C. J. S. W. 



Date of birth; birthplace; birthplace of father; 

 birthplace of mother; occupation (including class in 

 college, or, it not a student, the last educational in- 

 stitution attended); occupation of father; any mea- 

 surements previously made. B. C. J. S. W.

 B. C. J. S. 



Mother's maiden name; number of brothers ; sisters; 

 order of birth ; age of parents at birth ; birthplace and 

 occupation of grandparents. W. 



Two schedules of observations and records to be 

 filled in, one by the recorder and one by the subject, 

 as in the Columbia tests, vfith such modifications as 

 experience shall make desirable. C. 



A blank to be filled in by the recorder, noting 

 asymmetry of head or body, color of eyes and hair, 

 complexion, degenerative or other stigmata of head, 

 eyes, ears, mouth, teeth, hands or feet, posture, gait, 

 manner, coordination and speech, indications of in- 

 tellectual, emotional and moral characteristics. W. 



Physical Measurements : C. J. S. B. W. 



Height, weight and size of head. C. J. S. B. W. 

 Breathing capacity. C. J. S. W. 

 Height sitting. C. W. 



* We refer especially to two publications for de- 

 scriptions of some of the tests: Official Catalogue of 

 Exhibits, Department M., World's Columbian Expo- 

 sition; Section of Psychology, Joseph Jastrow in 

 charge, 1893; and Physical and Mental Measurements 

 of the Students of Columbia University, J. McKeen 

 Cattell and Livingston Farrand, Psychological Re- 

 view, Nov., 1896. The following papers on the sub- 

 ject may also be mentioned: 'Mental Tests and 

 Measurements,' J. McK. Cattell, with an appendix 

 by Francis Galton, 3Und, 1890; Zur Individual Psy- 

 chologie, Hugo Miinsterberg, Ceniralblatt f. Nerven-

 Mental and Physical Development of School Chil- 

 dren, J. A. Gilbert, Studies from the Yale Laboratory,

The measurements should be made in the metrio 

 system. The weight should be taken in ordinary 

 indoor clothing. The height should have the height 

 of the heel subtracted. At least the length and 

 breadth of the head should be measured. B. C. S. 



Keenness of Vision : B. C. J. S. W. 



Tlie maximum distance at which diamond (4 J 

 point) numerals can be read with each eye singly. 

 B. C. J. S. 



The illumination should be in the neighborhood of 

 100 candle-meters; about eight out of ten numerals 

 should be read correctly at the rate of about 2 per 

 second. The minimum distance should also be de- 

 termined, if possible. B. C. 



In addition or as a substitute, drawing a series of 

 forms as recommended. J. 



Use Snellen Test-types. S. 



Some other substitute for these tests, to be sug- 

 gested after satisfactory trial. W. 



Color Vision : B. C. J. S. W. 



Select as quickly as possible four greens from a 

 series of wools; measure the time; if long, make fur- 

 ther tests. C. 



Combine with test of rate of perception by requir- 

 ing subject to name, as rapidly as possible, a series- 

 of colors, either wools or papers. B. W. 



Use the chart exhibited at the World's Fair. J. 



Keenness of Hearing : B. C. J. S. W. 



The distance at which a continuous sound can be 

 heard with each ear singly. C. B. W. 



Use some artificial external meatus if the test is to 

 show small differences in sensibility. W. 



The sound should be from a watch reduced to a . 

 standard. An arrangement should be used, by which . 

 it can be periodically cut off without the knowledge 

 of the subject. C. S. B. 



Use for this a stop-watch. J. S. 



I endorse the stop-watch ; it can be manipulated, 

 so that the time is recorded, showing how long it 

 took the subject to decide that the watch has stop- 

 ped. J. 



Perception of Pitch : B. C. J. S. 



Adjust one monoohord or pipe to another, the tones 

 not to be sounded simultaneously. C. J. 



Select a match from a set of forks, making a fixed 

 number of vibrations per second more or less than a 

 standard, e. g, standard 500 v. per second ; other forks, 

 497, 497.5, 498, 498.5, etc.; 500, 500.5, 501, etc. B. S. 



I prefer the adjustment to the selection method. 

 The test can be made with two Gilbert tone-testers. J. 



Fineness of Touch : C. J. S. W. 

 The sesthesiometer is unsatisfactory; the discrim-
