them all ?” Leitz’s great feature is that he confines him- 
self entirely to microscopes and their accessories, instead 
of producing scientific instruments of every description as 
English opticians generally do. Herein lies his success. 
With a large and regular demand for certain fixed mod- 
els, a system of production in which machinery plays an 
important part is possible, and ensures sound construc- 
tion with a minimum of cost. The supervising and test- 
ing departments are of the most thorough description, 
and when the care that is taken is known, it is not to be 
wondered at that the Leitz objectives are credited with 
being more uniform in quality than any others. 
It has many times been stated that the reason why Con- 
tinental houses produce cheaply is because they employ 
women workers. Leitz has no female labor at all; all his 
men are skilled mechanics, the majority of whom have 
been trained in the works. 
It is quite possible for English houses to compete suc- 
cessfully with foreign competitors if they do but adopt 
their methods, which may be summarised in afew words. 
Have the works in a country town where rents are low, 
and the cost of living less than in a city. Have suitable 
buildings for workshops, and the rest is a matter of sys- 
tem and machinery. 
THE QUEKETT MICROSCOPICAL -CLUB.—The practical 
work done by this Society, which was’founded in the year 
1865, is recognized as being of the first importance, 
The meetings are attended by the foremost microsco- 
pists of the day. The journal, which is published bi-annu- 
ally, and gives reports of the papers read and the pro- 
ceedings generally of the club, is always worthy of care- 
ful perusal, but the great characteristic feature of the club 
is the welcome it extends to the amateur microscopist and 
the means it affords for bringing the novice into touch 
with the sound principles of manipulation, working and 
collecting.
