We have just enjoyed a call from Mr. Turner of the Gund- 
lach Optical Co., of Rochester, N. Y. Mr. Turner brought the 
very latest products of Mr. Gundlach’s acknowledged genius. 
One new piece of work is a one-fourth objective changeable to 
a one-inch. Another is a one-twelfth dry objective, of 165°, es- 
pecially made for work on the bacteria. It has the advantage 
of being used dry, of giving plenty of light, and of having a 
good working distance. The priee is also very reasonable in- 
deed, $40. Mr. Turner says they are coming rapidly to the 
front, and they intend to push things in the future more than 
ever. Myrowitz Bros., of 297 Fourth Ave., New York, handle 
their goods now exclusively. 
The Palmer slide Co., of Geneva, N. Y., now offer not only 
their beautiful beveled slides, but they also offer the Pillsbury 
cabinets, the Pillsbury mailing cases, the Syracuse solid watch 
glasses, mounting media, stains, and microscopists’ slides in gen- 
eral. Send for their late circulars. 
RESPIRATION OF LEAVES IN THE Dark.—Leaves placed in an 
atmosphere of carbonic acid, in the dark, absorb a considerable 
quantity of the gas.
