Editorial Comment. 191 
wisdom teeth are large with the crowns worn more than half way 
down, smoothly and with the surface inwardly oblique. The incisors, 
canine and premolars also show the same extreme wear with the in- 
ner, or buccal surface worn away deeply. Three teeth and three al- 
veolae are preserved in the maxillary bone, all the teeth much worn 
except the second molar which was above the diastema left by the loss 
ot the molars below. This tooth shows little or no trace of wear, in- 
dicating the loss of the lower molars at a time long prior to the death 
of the individual. There is no indication of the ridges above tj^e gen- 
ial tubercles on the inner side of the mandible in front, said to be char- 
acteristic of the Homo neanderthalensis- The cranium has a remark- 
able resemblance to one of a mound-builder recovered from a mound 
near Kansas City some years ago. The two halves of the mandible 
appear to have been broken in two either at the time of death or after- 
wards, as they were found separated, if the testimony of the finders 
is to be relied upon ; their extremities also indicate an original separa- 
tion of the parts by the hard matrix attached to them. 
Prof. Williston also writes, Aug. 26 : From a recent examination 
of the Lansing bones I find that they belong to a female between five 
feet two inches and five feet four inches in hight. They are un- 
usually small, even for a female ; the forearm is unusually long ; the 
pelvis not very broad. The woman was not less than forty years of 
age. 
Again Prof. Williston writes, August 31, 1902: A further and 
careful examination of the bones of the "Lansing skeleton" proves 
conclusively that there are two skeletons. The jaw found at a dis- 
tance (as I understand) is that of a child about 10 or 11 years ot age, 
as is shown by the presence of uncut canine tooth and of a deciduous 
molar. Please, therefore, correct my statement p-'iviously sent th^t 
the upper first molar showed little wear, — thvis indicating the removal 
of the lower molars at a much earlier time. This jaw (the upper) 
belongs to the child. 
It was noticeable that there is some irreg'ularity in the 
size of the teeth, viz. : the canine teeth are small, resembling" 
incisors, and are followed, backward, by two similar incisor- 
like teeth in place of distinct bicuspids. 
The important qtiestion lies in the ag'e of the loess cover- 
ing the skeleton — was it of the high-water stage of the Wis- 
consin epoch, or of the lowan? There was not stifificient time 
at hand to enable the party to go into a thorough examination 
of the valley with a view to determining the question with cer- 
tainty. There is not, in the immediate vicinity any stifficient evi- 
dence of the existence of terraces, whether of residuary or 
constructional origin, ylong that part of the great valley ; but 
at Council Bluffs, in Iowa, north of the city, is a distinct rem-
