Psycho-analysis is a lengthy process, demanding 
much tact and ingenuity from the psychologist or 
physician, but its results are of such surpassing 
interest and value that it should be regarded as one 
oi the most important methods of mental science.

THE SURVEY OF INDIA.) 
THs general report for 1g11-12, which has lately 
appeared, states concisely the progress made in 
the various departments of the Survey of India, the 
detailed descriptions and discussions of results being 
present in vol. iii. of the Records of the Survey. In 
the year under review, Colonel S. G. Burrard, F.R.S., 
was confirmed as Surveyor-General in succession to 
Colonel F. B. Longe. Topographical surveys were 
pushed on in various parts of the country, and work 
was done to meet some special requirements, of which 
may be mentioned the large-scale map of the Delhi 
site, with contours at 5 ft. vertical interval for the 
use of the town-planning committee. On the Geodetic 
Survey the astronomical latitudes of eleven stations 
were determined, and at one of these, Bihar, the 
largest southerly deflection of the plumb-line as yet 
found in India was found. Pendulum observations 
were made over the same region. In the principal 
triangulation the Sambalpur meridional series was 
commenced, and carried from lat. 23° to lat. 22°. In 
Kashmir secondary triangulation was carried along 
the Hunza and Kanjut valleys to form a connection 
with the Russian triangulation in the Taghdumbash 
Pamir. 
The field detachments of the Magnetic Survey were 
employed on the detailed examination of the Deccan 
trap area in Central India and Hyderabad State, 
where considerable abnormalities exist. Comparative 
observations were made at the survey base stations, 
and a large number of repeat stations were visited for 
observation. In the Map Publication Office orographic 
colouring, by means of a series of colour tints from 
light green through yellows, browns, purples, and 
red, has been adopted for the one-millionth scale in 
place of shading as facilitating the provision of in- 
formation. These sheets differ in size and in the 
unit (foot) of the vertical measurements from those 
of the international map, but as they form the key to 
the whole system of nomenclature and the arrange- 
ment of the topographical sheets, they cannot be 
dispensed with. 
A series of ‘‘departmental papers”’ is to be com- 
menced. These will be numbered serially, and will 
include all papers which, being published for de- 
partmental use, do not fall within the scope of 
the ‘Professional Papers,’’ and are not of public 
interest. 
Those, however, who are interested in the technical 
details of surveying will turn rather to the third 
volume of the Records of the Survey of India, where 
full accounts of this work will be found. Topo- 
graphical surveys included triangulation, levelling, 
traversing, and detailed measurement on _ various 
scales from 1 in. to one mile, to 20 in. to one mile 
in cantonment survey. Many points of interest and 
modifications in procedure are noticed, among which 
we may mention the experimental use of Bristol 
boards instead of drawing paper on the plane-tables 
used in the field. If these are fastened firmly to the 
board by one edge only, and loosely by cloth slips

on the other sides, the trouble arising from distortion 
of the sheet when working in very dry climate is 
greatly reduced. Further experience with these 
boards is awaited. 
In geodetic work the use of a new and more power- 
ful zenith-telescope is reported, and determinations of 
latitude were made with it at eleven stations. Of 
these all stations but one, Khajnaur, on the north 
side of the Siwalik Hills, the attraction of the plumb- 
line is southerly, the largest value being at Biharas, 
mentioned above. In the pendulum work, observa- 
tions were made to the north of the Ganges in a 
region which showed unusually low density, and it 
is suggested that Rarachi, situated on the edge of 
the high plateau which forms the southern edge of 
the Ganges valley, may be near the crest of a ridge 
of high density. An important piece of work in this 
connection was an investigation of the isostatic theory 
of Mr. Hayford, with respect to a number of Indian 
stations, and the results obtained for the above- 
mentioned stations are given. In the account of pre- 
cise levelling it is mentioned that experiments are 
being carried out with a new pattern of aluminium 
staff. 
A full account of the magnetic survey and work in 
the observatories is given, but this calls for no special 
remark. In an appendix is given a synopsis of 
geodetic work near Dehra Dun, which is illustrated 
by a map showing the triangulation and_ gravity 
observation stations, as well as the lines of precise 
levelling. The whole volume forms a valuable con- 
tribution to the literature of high-grade eu 
THE ASSOCIATION OF TECHNICAL 
INSTITUTIONS. 
ae twenty-first annual meeting of the above asso- 
ciation was held at the Clothworkers’ Hall, 
Mincing Lane, on January 30 and 31 last, and was 
attended by upwards of 120 delegates representing all 
the important technical institutions in the United 
Kingdom, of whom about ninety-seven are enrolled 
in the association. 
The new president, Sir Alfred Keogh, K.C.B., on 
taking the chair, delivered his inaugural address, in 
which he dealt with the report of the Royal Commis- 
sion on the reconstitution of the University of London, 
and especially with that part of it concerned with 
technological studies. He expressed great satisfaction 
with the position accorded to the faculty of technology 
in the proposals of the Commission, particularly with 
respect to the methods of administration and with the 
prominence assigned to the sphere of utility in educa- 
tional questions. 
The Commission recommended the establishment of 
a self-governing faculty of technology in the Univer- 
sity, such faculty to embrace all branches of applied 
science. He dwelt upon the extreme importance of 
bringing the specialisation of science well within the 
sphere of the University, and expressed gratification 
that entrance to the University would be made more 
accessible to the fit student with greater freedom for 
the teacher. 
Various questions of considerable importance to the 
well-being of technical institutions were considered. 
Amongst them, the registration of teachers and the 
proposals of the newly established Teachers’ Regis- 
tration Council. Great satisfaction was expressed 
with the happy solution of this extremely difficult 
question by means of which the profession of teacher 
had been unified, and it was unanimously agreed that 
it was desirable that all eligible members of the teach- 
ing staffs of technical institutions should seek enrol- 
ment.
