Conclusion. 
The substantial advances made in this country in 
pyrometry during recent years may be cited as a 
useful guide as to how industry may be created and 
preserved. All the places at which pyrometers are 
made in Britain are under the direction of skilled 
scientific men, who are constantly devising new 
instruments and finding wider fields for their applica- 
tion. All are in close touch with the National 
Physical Laboratory, which has proved invaluable to 
them in securing uniformity of calibration, and in 
other ways. The result is a thriving and extending 
industry, not threatened by foreign competition, and, 
not requiring artificial props to ensure its success 

MEMBERS OF SCIENTIFIC STAFFS OF 
UNIVERSITIES, COLLEGES, AND OTHER 
INSTITUTIONS ON ACTIVE SERVICE 
WITH H.M. FORCES. 
SINCE the publication, in our issue of July 15, of 
the list of members of scientific staffs of univer- 
sities, colleges, and other institutions on active service 
with H.M. Forces, we have received further lists 
which for various reasons did not reach us earlier. 
The names in the list subjoined are supplementary to 
those published in our register last week. In each 
case the list is limited to men who have been gazetted 
or have enlisted in one of the Services. 
At the Meteorological Office permission to offer their 
services to the War Office or other Government depart- 
ment associated therewith for the period of the war 
has been given to Mr. G. I. Taylor, Schuster reader 
at Cambridge, and twelve members of the clerical and 
technical staff. Three of the attendants have left the 

service of the office to enlist. On the other hand, the |

professional and scientific staff has been increased for 
special duty in connection with meteorological field 
service by the addition of six meteorologists, three of 
whom are volunteers. More volunteers with profes- 
sional qualifications in physics and mathematics are 
required for ckity at the observatories.
