NOTES AND COMMENTS. 
YORKSHIRE BY PEN* AND PICTURE. 
With the above title Messrs. A. Brown & Sons, Ltd., of 
Hull, have published an exceedingly well illustrated book of 
216 pages, measuring 14^ inches by 10 inches, well bound, 
and with an artistic cover. It includes a brief description 
of the history, etc., of the principal places in the county, in 
connection with which the natural history and geological 
features have not been neglected. There are also many fine 
reproductions from photographs and old prints. It is sold 
at the extraordinarily low price of is., possibly due to the 
number of advertisements, of which there arc many. Un- 
fortunately the volume does not appear to be dated. As 
the letterpress is edited by Mr. T. Sheppard, we are not in a 
position to offer any adverse criticism. 
INVESTIGATION OF YORKSHIRE RIVFRS. 
A circular has neen issued by the Hon. Secretary of the 
Yorkshire Geological Society, suggesting that Yorkshire 
geologists should scientifically investigate our Yorkshire rivers. 
It is pointed out that ‘ the main lines of the work would be as 
follow" : The various river basins would be defined, and one 
or more selected for a complete study. Or it may be advisable 
to call for volunteers from our members and all others interested . 
such as waterworks engineers, to investigate a number of the 
most accessible rivers. For example, the Calder may be 
undertaken by members residing in Mirfield, Wakefield, etc., 
and these w r ould collect particulars of rainfall, variation of 
volume with respect to rainfall, variation of velocity with 
volume, formation and movement of gravel and sandbanks, 
erosion, dissolved and suspended matter.’ 
AEROI.ITE IN LANCASHIRE. 
At the recent meeting of the [Manchester Literary and 
Philosophical Society Mr. C. W. Jenkins exhibited and des- 
cribed an aerolite which fell at L’pholland, near Wigan, on 
October 13th. ‘Soon after its approach a violent explosion 
was heard throughout Lancashire, Cheshire and the sur- 
rounding counties. The result of the explosion is evident 
from the parts which w r ere fractured before its entry into the 
earth. It is the largest ‘ find ’ in England for 120 years. A 
stone of 3! lbs. fell at Middlesbrough in 1881, and a fall of iron, 
weighing yf lbs., occurred in Shropshire in 1876. The weight 
of the two pieces exhibited w r as 28 lbs. 13 oz., and there is 
evidence that some 2 lbs. or so is missing. The constituents 
are mainly basic silicates, with iron and nickel.’ We notice- 
there is a record of the fall in The Lancashire and Cheshire 
Naturalist for October. It is there stated ‘ Unfortunately the 
meteor w-as removed and trace of it appears to have been lost.’ 
It has evidently been found again.
