s not available and it is desired to avoid the expense and trouble saturators may be used with advantage.
This saturator, which is made only by Messrs. Newton & Co., Christ’s College, Christchurch, New Zealand, for
designed _
use in the laboratory there.
It has considerable advantages overthose in general use here, as there is a supply of spare ether which keeps the flannel packing always equally saturated, and so prevents the diminution of light experienced with most patterns after they have been working for some time. Even with a large bore jet the saturation with the “Newtonian” saturator is perfect for over three hours.
. . hung through a hole in the table or lantern box, as is intended, it is impossible to upset it, and the construction is so simple that the packing can readily be removed for drying, while there is nothing to get out of order, and the possibility of leakage is reduced to a minimum.
It can be used with any good mixed jet.
Being made throughout in our -own workshops, it is, of course, of sound and excellent workmanship.
