Lilley came from an old New England family, one which is in 
no danger of the extinction which appears to threaten some of 
the old colonial families, if we may judge from the information 
given the writer in the letter written at Christmas time. At that 
time Mr. Lilley assumed responsibility for 55 descendants,— 9 
children, 27 grandchildren, and 19 great-grandchildren. 
Beginning his education in a backwoods school of Pennsylvania, 
Lilley learned to write with a goosequill pen dipped in witch- 
hazel juice extracted in an iron kettle. He commenced teaching 
in the same schoolsi at the age of 18. In his genealogy of the 
Lilley and Smith families he states that reading the “rocky pages 
handed down from long ago” has been “the source of more pleas¬

To paleontologists the following quotation from Professor New¬

this tireless collector, who still delighted in the companionship

among them the representatives of several new genera and species, 
of which brief descriptions are given on the succeeding pages.”

Lunar Pertrifactions. With the increasing high-powers of the 
modern telescope, it will soon be time for someone to announce 
the discovery of fossils on the Moon. The names Lunaceras and 
Trilunabite are hereby reserved for that occasion. If the discovery 
be authoritative, a discussion of lunar inhabitants concealed on the 
off-side of that globe will follow, as a matter of course; and the 
door to controversy, closed just lately by a well written article on 
“Life in Other Worlds,” in Science (Vol. LIV, p. 329), will again 
be open. Of course it may be necessary to demonstrate that life 
on the Moon has been the real cause of the volcanic phenomena 
visible on the near side of it. To anyone who may say that such
