KANSAS CITY REVIEW OF SCIENCE. 
General Passenger Agent W. F. White, 
of the Atchison, Topeka & Santa Fe R. R., 
with characteristic liberality gives the Press 
Association of Kansas an excursion to Chi- 
huahua, 0!d Mexico, on the loth inst., which 
will doubtless prove an extremely gratifying 
and instructive trip, and one which will re- 
sult in a more full and complete ''writing- 
up " of that comparatively unknown portion 
of the continent than it has ever received. 
Having accepted an invitation to accompany 
the party we shall pay especial attention to 
the geological, mineralogical, meteorological 
and archaeological features of the country 
along the whole line, so as to be able to give 
the readers of the Review at least a general 
idea of its most attractive points in the June 
issue. 
Col. A. C. Dawes, the genial General Pass- 
enger Agent of the Kansas City, St. Joseph 
& Council Bluffs R. R., on the same day 
starts the Missouri Press Association on a 
delightful excursion trip to St. Paul, Duluth 
etc. Being a member of this Association and 
having heartily enjoyed several editorial 
jaunts with it, we hesitated which road to 
take, but finally concluded that we could not 
forego this rare chance to " revel in the Halls 
of the Montezumas." 
Professor Chas. E. Munroe, of the U. 
S. Naval Academy, is publishing a series of 
notes on the Literature of Explosives, and 
asks authors, publishers and manufacturers 
to do him the favor of sending him copies of 
their papers, publications, trade circulars, or 
expert testimony in infringement cases. 
The tornado season has commenced. For 
the next two months we are liable to feel 
their effects at any time. In this connection 
we call attention to the articles written by 
Mr. Finley, of the U. S. Signal Service, and 
published last June and July in the Review. 
They will be found to cover the whole sub- 
ject very fully indeed. 
We learn from Mr. J. P. Finley of the U. 
S. Signal Service, that the unsettled question 
of the origin of atmospheric electricity is re- 
ceiving especial attention at present from the 
Johns Hopkins University and similar insti- 
tutions in England, France and Germany, 
the immediate object being to determine defi- 
nitely the most approved methods of investi- 
gation. Delicate and costly experiments are 
now being made with this end in view. 
We are indebted to Prof. A. V. Leonhard, 
of St. Louis, for a copy of his paper upon 
The Occurrence of Millerite in St. Louis, il- 
lustrated with four beautiful artotype plates. 
Millerite is the minerological specialty of St. 
Louis, not having been found anywhere else 
in such abundance and so beautifully devel- 
oped. 
The interesting and thoughtful article up- 
on " The Age of the Missouri River " in this 
number of- the Review was delivered by 
Judge E. P. West before the Kansas City In- 
stitute. It has been published in a neat 
pamphlet and is to be sold for the benefit of 
that association at 25c per copy. 
All subscribers to the Review desiring 
their copies bound can have it done in half- 
morocco for one dollar a volume by leaving 
their back numbers at this office. 
Mr. E. p. Vining, Freight Traffic Manag- 
er of the Union Pacific Railroad, at Omaha, 
in remitting for the Review, says "I con- 
sider the vocabularies of the South American 
Indian languages, by Dr. Heath, contained 
in your. last issue well worth the cost of a 
year's subscription." 
Prof. James H. Canfield, of the State 
University of Kansas, has commenced the 
publication of a monthly Index of Periodical 
Literature, to contain the alphabetical and 
topical contents of all magazines sent him 
for the purpose and to be distributed gratui- 
tously among the institutions of learning and 
libraries throughout the State. He expects 
to obtain sufficient advertising patronage 
to pay expenses of publication, and to re- 
munerate himself by the large number of 
periodicals he will receive.
