ing places in the objects of the association, and we have seldom 
seen such hearty good will and fellowship extended to scientists 
as were given by the citizens and by the great railroad corpora- 
tions of the west. If appreciation of scientific work by the multi- 
tude is one step in advancing science, the results of the last 
meeting must be considered as most favorable. i 
Neither can we review the papers received and discussed, and 
glance over the names of the members present, without feeling that 
in these respects also the meeting was successful; though admit- 
ting that there was not that sharp overhauling of some crude 
papers which has sometimes taken place to the purification of 
science. In fact, the only drawback to the meeting was the lack 
of critical discussion of some of the papers, which were read and 
allowed to drop without the criticism they would have received at 
a larger meeting when more persons working in the same field 
would have been brought together. 
The small number of members present (about 188) left several 
of the subjects which usually have a goodly number of adherents 
very limited in their support, and though about half of the hun- 
dred papers admitted to a place in the programme were referred to 
the Natural History section, to which we shall confine our remarks, 
there were not enough to cause the division of the section into 
subsections, and the bulk of them fell as usual under the head of 
Geology, In Botany there was but one, and that was the able 
address of the retiring President, Prof. Gray, which we gave in 
fallin our last number. In Zoology there were the three by Prof. 
Morse on the “ Oviducts of the Brachiopods,” the “ Embryology of 
Terebratulina,” and ‘ Observations on living Rhynchonella ;” the 
very interesting and carefully prepared paper by Prof. Riley “On 
à new genus of Tineidæ and the singular connection of the insect 
With the fructification of the Yucca,” which was one of the best 
Papers read in the section; that on “ Organic Vigor and its rela- 
tion to Sex,” by Prof. Hartshorne ; and one on “ Zoological Barri- 
ers,” by Prof. Orton. In Paleontology, the two papers by Prof. 
Sope and one by Col. Foster were important in presenting pew 
discoveries ; while the paper by Dr. Day on the “ Eye of Trilo- 
bites,” gave an opportunity for a discussion on the position of the 
Trilobites among the crustaceans.
