toad, tapir. Of shells, two species of Io, seven of Unio, 
two of Paludina and Trypanostoma were found. Most 
“important of all, in the opinion of the explorer, were 
remains of the peccary,and tapir. Teeth of the latter, 
the speaker stated, were found so near the bottom of the 
deposit that they may have belonged to the lower alluvial 
strata, and not to the period of the human remains. In 
the discussion on the paper President Brinton stated that 
the tapir was commonly regarded as a South American 
animal, but that within our century it had been observed 
as far north as the Isthmus of Teotehuntepec, and that it 
was not necessary to take refuge in the theory that the 
teeth of the tapir belonged to the lowest strata, as it is 
not unlikely that the tapir existed in the Gulf States 
within a comparatively recent time. Mr. Mercer gave an 
account of an Indian ossuary that he found in a rift in the 
Lookout Cave, and exhibited specimens of charred femurs 
and the fragment of a pierced gorget, with stone arrow 
points from this deposit. In conclusion, he urged the 
importance of a thorough exploration of the caves of the 
entire country as likely to settle the question of early 
man in America. Dr. Brinton did not think the absence 
of objects of a primitive type in caves as conclusive with 
reference to the absence of primitive man. Early man 
was probably arboreal, and did not live in caves at all. 
According to the best French archeologists, the man of 
the river drift was older than the cave man, and his bones 
are associated with remains of a fauna that required a 
tropical climate for their development. The fossil 
remains from the explorations were exhibited at the close 
of the meeting. 
—It is with deepest regret that we announce the destruc- 
tion by fire of the new Engineering Laboratory at Purdue 
University, LaFayette, Ind. It was burnedon the night 
of Jan. 23—four days after its dedication. The fire 
originated in the boiler room and spread with great 
rapidity. Its progress could not be checked until the

larger part of a fine building had been destroyed. Three 
laboratory rooms were burned ; the machine room with 
its twenty lathes, its planers, shapers, drill presses, mill- 
ing machines, and its large supply of small tools ; the 
forge room with its thirty-two power forges ; and the 
laboratory for advanced work, which contains Purdue’s now 
famous locomotive ‘‘ Schenectady,” a triple expansion 
Corliss engine and much other apparatus designed for 
work in steam engineering, hydraulics, and strength of 
materials. Nothing in these rooms escaped the fire. Not 
only was all the apparatus lost but also a large amount of 
experimental data. The main portion of the building was 
also consumed. This contained three stories, 50 feet by 
150 feet. It was occupied by drawing rooms, recitation 
and lecture rooms, instrument rooms, offices and a me- 
chanical museum. Some of the furniture and apparatus 
in these rooms was carried out before the fire took posses- 
sion, but, as already stated, this part of the building was 
entirely burned. The only portion still standing com- 
prises the wood room and foundry. ‘These rooms were 
not damaged except by the temporary removal of the 
more portable portion of their equipment. The inci- 
dental losses by the fire are considerable. Members 
of the faculty have lost books, papers and data: 
students, their instruments, and manufacturers, in every 
part of the country, who, by gifts or liberal discounts, had 
coéperated in the equipment of the building, have lost 
their representation there. The excellent facilities for 
laboratory training which Purdue has been able to offer 
have made her engineering departments well known and 
have helped to draw to them a large number of students. 
It is hoped and expected that the new building will be 
quite as extensive and its equipment quite as complete as 
were the building and equipment which have been lost, 
and, since experience has suggested the modification of 
many details, it is but reasonable to expect the second 
plant to be better than the first.

7 ARYOKINETIC FIGURES IN MAMMALIAN 
TISSUES.—Since the publication of my Prelim- 
inary Notice in Sezexce for Dec. 1, 1893, many parties 
have written me asking for permanent preparations show- 
ing mitosis. To these parties I have sent slides, and I 
now offer to all who desire them slides showing mitotic 
figures in nuclei of embryo kitten. A good immersion 
objective is necessary to make out the figures satis- 
factorily. Send 6ocentsin stamps. If the slide is not 
satisfactory, return it, and [ will return the money. I do 
not care to exchange slides, Frank S. Aby, State Uni- 
versity, Iowa City, lowa.

their stock of minerals, during the past six weeks, 
more choice specimens than during any similar period in

marked the prices very low, and as a further temptation 
to customers to forget the hard times, they have decided 
to allow a discount of ten per cent. on all minerals 
sold during the month of February.
