396 REPORT— 1903. 



The classes he has measured during the past 16 or 17 years are 

 the professional classes and criminals. His results are published in the 

 British Association Reports and in the ' Journal ' of the Anthropological 

 Institute. The objects of his oljservations were chiefly to determine 

 racial differences and range of variation, and for identification. Assistants 

 thoroughly trained by himself have been employed. He considers that 

 tlie measurements taken should depend on the nature of the investigation. 



Gladstone, E.. J., M.D. (INIiddlesex Hospital), writes : ' I am at present 

 engaged in an anthropometric investigation, and the principal measure- 

 ments which I have taken are the stature and hothj iveiyhf, along with the 

 following head measurements : 



(/) Length — from glabella to occipital point. 



(b) Breadtli — greatest transverse diameter above zygomatic arches. 

 (//) Height — fi'om biauricular line to vertex, 



('■) Circumference — taken in a horizontal plane, passing through a 

 point just above the glabella in front, and the occipital point behind. 

 ' \w l^ost-mortem subjects I have also recorded the weight of the brain.' 



' My measurements have included the following groups : — 



' The Students of the Middlesex Hospital, 

 ' The Medical Staff of the Middlesex Hospital. 

 ' The Porters and Male Servants of the Middlesex Hospital, 

 ' Boys of St. Katherine's School, Regent's Park. 

 ' 100 Female Inmates of St. Pancras Workhouse. 

 ' 50 Male Inmates of St. Panci'as Woi'khouse. 



' Male and Female Subjects in the j^ost-mortem room of the Middlesex 

 Hospital. 



' I inclose the schedule which I have used to record data, for the first 

 three groups ; I have however, in addition to tlie items indicated in it, 

 taken full and profile photographs of the head and shoulders, and the 

 horizontal contour of the head. 



' 2. I have used your (Gi'ay's) callipers for taking the longitudinal and 

 transverse diameters of the head ; and the instrument you had made for 

 me for taking the height from the biauricular line to the vertex. In 

 using this I take special care that both the head and the instrument are 

 held vertical. 



' 3. My first measurements were taken in May 1901, and I have 

 continued taking measurements up to the present time (1 year 10 months). 



' 4. In November of last year (1902), I gave a j^i'eliminary communica- 

 tion embodying some of my results to the " Anatomical Society of Great 

 Britain and Ireland," and showed a series of tables giving the average 

 measurements of different groups ; the Society are publishing the com- 

 munication with the tables in the " Journal of Anatomy and Physiology." 

 This commujiication does not include the records from the ■post-mortem 

 room, which are not yet complete, and in making use of these I hope to 

 have the assistance of Professor Karl Pearson. 



' 5. One of my chief objects in this investigation has been to determine 

 whether there is, or is not, any variation in the size and shape of the 

 head correlated with varying degrees of mental ability ; and if so in 

 what direction, and to what extent. In carrying out this part of the 

 inquiry I have classed the individuals composing the first two groups, and
