THE NATURALIST AND COLLECTOR 
43 
Besides the continuance of articles 
in this number it will present illus¬ 
trated articles by Dr. Morris Gibbs, 
Will C. Hall etc.,—these names alone 
being' a sufficient guarantee of its 
value. To those who may wish this 
number separately, it will be sent on 
receipt of a silver dime.

Owing- to the lateness of the issue of 
our June number those living- in remote 
districts, may have been debarred 
from taking advantage of our clubbing 
offer with the Museum. For this 
reason we will extend the time indefi- 
nately, so that, all who so desire may 
have the privilege of accepting this 
remarkably cheap offer. This offer 
does not, as you know, include the 
“giving away”, of cheap supplies or 
worthless specimens as premiums, but 
includes two of the most neat, artistic 
and interesting publications now 
issued. This issue, together with the 
preceeding one, while it has not 
reached the standard which we wish it 
to maintain, gives a general idea of its 
character and the contents. The 
“Museum,” considering the short time 
it has been published has met with 
phenomenal and unprecedented success 
The fact of its rapidly increasing 
circulation indicates the position of es¬ 
teem which it holds with the natural¬ 
ists of our country. It gives each 
month thirty-six or more pages of val¬ 
uable reading matter on the subjects of 
botany, ornithology, geology, etc. The 
regular price of the Museum is one dol¬ 
lar per year and is well worth more. 
The price of this paper is seventy-five 
cents, but for a short time only, we 
will make a special price of both for 
one dollar. Remember, in accepting 
this offer, you do not get a supply of 
worthless specimens, but two of the 
most popular and meritorious journals 
that are at present issued—something 
that wdll remain standard as long as 
the natural sciences are studied. 
t t t 
As our advertisements in the natural¬ 
ists’ papers appeared so close to the 
time of the appearance of the June 
number, we will extend this time also. 
Till August 15th, we will receive sub¬ 
scriptions to the Naturalist and Col¬ 
lector at the advance rate of fifty 
cents; in clubs of four, only thirty-five 
cents—less than half the regular price. 
At this price you will be getting what 
is pronounced by everybody who has 
been fortunate enough to receive a 
copy, to be the best publication of its 
kind ever issued. All should avail 
themselves of this offer at once, as it is 
made for but a short time. All who 
have previously sent in their subscrip¬ 
tions at the regular rate will have their 
time extended to eighteen months. As 
we state in another place, please do 
not send stamps. Simply cut a hole in 
a piece of cardboard, insert money, 
paste paper over both sides and send at 
our risk.

On account of the necessary delay 
in issuing- the first number, we are com¬ 
pelled to change the date of publica¬ 
tion. Rather than combine two num¬ 
bers as is the usual resort, we have de¬ 
cided to change the date of publication 
from the first to the fifteen! h of the 
month. We trust this arrangement 
will be satisfactory to our readers. 
O N HEATING minerals in a 
vacum and examining the gas 
thus obtained, Prof. Norman 
Lockyer has already found about sixty 
spectral lines that are believed to be 
new to terrestrial chemistry. Several 
unknown gases are indicated.
