1876.] Microscopy. 185 
To allow ample time for preparation, and to facilitate the coöperation of 
all interested parties, it was decided to adjourn for one year, and to pro- 
with the organization at the Buffalo meeting of the association, 
which commences on the third Wednesday of August next and continues 
about one week. All persons interested in the microscope, and desirous 
of joining such an organization as is now proposed, are invited to be 
present and cobperate, whether at present members of the association or 
not, and are requested to bring to the meeting original papers of scien- 
tific interest upon subjects connected with the microscope and its work, 
and also to bring instruments, accessories, and objects, especially those 
illustrating new or unfamiliar inventions, contrivances, and discoveries. _ 
It is hoped that the participation of microscopists in this movement 
will be prompt and cordial. The general desire for a national organiza- 
tion has become a positive necessity, and it is believed that success could 
be in no other way be so fully obtained as by meeting in connection with 
the American Association, whose character and influence could not fail to 
be an advantage, whose meetings are necessarily held only at the most 
available times and places, and whose elaborate arrangements for the 
convenience and economy of members attending are designed for the 
efit of scientists in every department. The recent accession of the 
chemists, the ethnolovists, and the entomologists marks the tendency of 
the association to become a general congress of American scientists. 
In meeting with the American Association the microscopists will enjoy a 
More than double advantage, but separated from it they would lose from 
their number those who desire to attend the meetings of the association 
and whose business or other convenience might interfere with the addi- 
tional journey and absence demanded by a second meeting. 
AMERICAN POSTAL Micro-Casinet Cius.— A year’s experience in 
the working of this organization has already given it the position of a 
Useful and well-sustained institution. The first announcement of the 
formation of the club was so favorably received that an unex ly 
ge number of members was enrolled, since which time its member- 
ship has steadily increased until it now numbers twelve circuits of mem- 
bers, distributed over the whole country east of the Rocky Mountains. 
ith the exception of a remarkably small number of accidents to objects 
While in transit by the mails, which it is believed will be still fewer in 
the future, the club has met with no practical difficulties or disappoint- 
ments. The general excellence as well as the variety of objects con- 
tributed has been conspicuous; and those members, if there are any, 
Who can learn but little from the work of others in various departments 
of the science must at least feel that they have contributed widely to 
the advantage of others at very little trouble to themselves. In addi- 
tion to the circulation and study of mounted objects, critical notes upon 
Same, questions and answers, and announcement of duplicates for 
exchange, it is proposed to add during the present year the exchange of
