peculiar markings developed within the Widmannstattian 
figures and called Dr. Smith's attention to them. The latter 
gave the fir^t description of these smaller figures in the 
American Journal of Science'- with a figure, and proposed ro 
name them Laphamite markings. These peculiar figures are 
portions of the area in general marked by the Widmannstat- 
tian lines, and instead of having their extremities rounded 
like the Widmannstattian lines, they have rectangular or 
concave extremities. These areas are marked by a much 
finer lining, indicating, as thought by Smith, the axes of 
minute columnar crystals produced by cooling on contacting 
with a cold surface, and this proving that the Laphamite- 
marked area was of later origin and molten when the Wid- 
mannstattian area was solid. A few years later Dr. Smith 
noted the same fine lining on a meteoric iron that had been 
preserved in the cabinet of the late Prof. Troost, and sa}*s : "In 
connection with these Widmannstattian figures I will call 
attention to the delicate parallel lines inside these figures, 
which I pointed out several years ago as being peculiar 
to certain of the irons, and which 1 designated by the 
term Laphamite markings. : 'j Dr. Lapharn prepared 
an elaborate list of all known American meteorites, 
with citations of authorities, but it was never pub- 
lished, bo far as known. Dr. C. I. Shepard urged him 
to submit it to the American Journal of Science. The 
Laphamite markings are also illustrated in the American En- 
cyclopedia (New Ed.) under the article "Aerolite." Some- 
what later Dr. Lapham gave particulars of the discovery of 
additional fragments of the "Wisconsin meteorite, making a 
total of 143 pounds. The six fragments were all found in the 
same field in the town of Trenton, Washington Co., about 'M) 
miles northwest from Milwaukee* 
Although Dr. Lapham did not publish much that could be 
called zoological, yet among his papers are several manuscripts 
wholly zoological. One is a "Catalogue of the Fishes of Wis- 
consin and the adjoining states: with a synopsis of the fami- 
lies, references to the places where they are figured and
