both in promoting the study of the mind, and in the 
training of young men to be teachers in colleges and 
high schools. He has also been deeply engaged in 
psycho-physie researches, soon to be published. Con- 
venient rooms and suitable apparatus for this work 
have been provided by the university. 
— Dr. William H. Welch, a graduate in arts of Yale 
college, and in medicine of the College of physicians 
and surgeons in New York, has been appointed pro- 
fessor of pathology in the medical faculty of the Johns 
Hopkins university. Dr. Welch is now pathologist 
to the Bellevue medical college in New York. He 
has given evidence of his ability as an independent 
investigator and as a skilful teacher; and, in connec- 
tion with the Johns Hopkins hospital and university, 
he will have an excellent opportunity to advance the 
science to which he is devoted. 
— Among recent contributions to invertebrate pale- 
ontology, we note Bulletin No. 2 of the Illinois state 
museum of natural history at Springfield, in which 
two new species of Crustacea, fifty-one of Mollusca, 
and three of Crinoidea from the carboniferous forma- 
tion, are described by Prof. A. H. Worthen. Should 
the publication of a supplementary volume of the re- 
ports of the geological survey of the state be author- 
ized by the legislature, the species now described will 
be fully illustrated. Meanwhile the typical speci- 
mens have been placed on exhibition in the state 
museum. 
_ — A notice of some new species of primordial fos- 
sils in the collection of the American museum of 
natural history, New York, with remarks on species 
previously known, by Mr. R. P. Whitfield, appears 
in Bulletin No. 5 of the museum. These organisms 
are chiefly Brachiopoda and Crustacea, and are illus- 
trated by two excellent plates. 
— The recent geological work of the New Jersey 
survey has been chiefly in connection with the creta- 
ceous formations, the artesian wells that they feed 
along the coast, and the crystalline rocks and their 
iron ores. The flowing well at Ocean Grove now 
yields a daily supply of sixty thousand gallons of 
sparkling, pure water, from a depth of about four 
hundred feet, or within twenty feet of the estimate, 
based on dip of strata, given by the survey in 1882. 
A second successful well has been lately bored in the 
same place. The drainage of the Great meadows, in 
Warren county, a work recommended by the survey, 
continues to show its efficiency: ordinary rains are 
quickly carried off; the autumnal and miasmatic dis- 
eases, formerly so much dreaded in its neighbor- 
hood, have disappeared; and the waste swamp-land, 
wherever brought into cultivation, shows a decided 
superiority over the surrounding high ground. Evi- 
dence is given to show the intrusive origin of the 
triassic trap-sheets of the Watchung (Newark) Moun- 
tains; and their crescentic outline is said to be *‘ such 
as would be expected from a vertical force pressing 
against an inclined stratum of rock.’’ Professor New- 
berry has nearly completed his monograph on the 
triassic fishes, and Professor Whitfield is at work on 
the invertebrate fossils of the New Jersey cretaceous.

— The annual report of the geological survey of 
New Jersey, by Professor George H. Cook, was re- 
cently published, and shows the same careful and suc- 
cessful administration of the survey that has been 
characteristic of it for several years past. In spite of 
the very limited cost, — ‘‘ the expenses of the survey 
are kept strictly within the annual appropriation of 
$8,000,’” — valuable and effective work is steadily ac- 
complished. The most considerable undertaking at 
present is the topographical survey of the state, in 
charge of Mr. C. C. Vermeule. The primary stations,

are provided by the U. S. coast-survey, and are now 
nearly completed. The plan of final publication of 
the state map in seventeen sheets is also shown. 
They will be on a scale of one inch to a mile, with 
contours every twenty feet in the hilly districts of the 
north, and every ten feet in the smoother country 
farther south. The surveys over the roughest and 
most difficult part of the state are now finished; and, 
although half the total area is not yet covered, it is 
said that more than half the labor is done. The 
state’s area is estimated to be 7,576 square miles. Of 
this, 1,116 square miles were surveyed last year, giv- 
ing a total of 2,856. 1,893 square miles have been 
mapped, and 1,691 engraved. When completed, there 
will be prepared, also, a general map, on a scale of 
five inches to a mile, of the whole state. This will 
be printed on a sheet twenty-four by thirty-four
