1889. | NEW YORK ACADEMY OF SCIENCES. 115 
forms. Still another series had changed so little that the lec- 
turer spoke of it as a persistent type; while other series which 
followed these, but sprang from the same common source, 
evolved into diminutive, degraded, and distorted shells, more 
or less uncoiled. 
The lecturer applied the laws of evolution, which could be 
seen to have governed the development of these different series, 
to the evolution of life-forms in general in the history of the 
earth. He then showed a series of views exhibiting the different 
stages of growth of the shell in the living Nautilus pompilius, 
and illustrated the laws of heredity and biogenesis by projecting 
on the same spot on the screen which had been occupied by the 
figure of the young of Nautilus the figure of the full-grown 
adult of a Silurian fossil, Cyrtoceras. The likeness was clearly 
perceptible to the audience, and was close enough to demon- 
strate the reality of the correspondence between the young of 
the existing species and the adult of its ancestor, which lived 
only in the most ancient periods of the earth’s geologic history. 
Mr. Freperick Braun exhibited further illustrations of the 
same subject, after the lecture, in a number of specimens of fossil 
shells, selected and arranged in sets to show relations and 
changes. 
A vote of thanks was unanimously tendered to Pror. Hyatt 
for his able discussion.

STaTED MEETING. 
The President, Dr. NEWBERRY, in the chair. 
Thirty-five persons present. 
Dr. Franz Boas exhibited a number of photographs of tat- 
tooed Indians from the Queen Charlotte Islands, B.C. This 
people, the Haida, are the only one in the habit of tattooing 
their whole bodies,—wrists, arms, breast, back, legs, and feet,— 
the designs being conventional representations of animals, the 
‘crest ” of the person on whom they are tattooed. The tattoo-
