THE GEOLOGIST. 
Fossil Piujit prom Uri'ER Coal Measures, near Bolton. — Dear Sir, 
— Having noticed your kindness in inserting any remark upon phenomena 
which may have passed under the notice of your readers, I take the liberty of 
making the following. The enclosed is a fruit I have obtained from a quarry 
in the upper coal measures, near Bolton. It occurred along with masses of 
Trigonocarpiim oliniforme, Nopf/r/erafliki, &c., togetlier with Calamite.i, Sigillariie, 
Lejiidodendron, and Calmia, &c. ; and tlie upper flag slialcs contain numerous 
impressions of ferns, chiefly Pecopteris loiichitim, Neuropterk, &c. The large

fruit is now in tlie possession of Mr. Biuney, of Manchester : it has six lobes, 
which ascend from the base and meet at the summit, and it is larger than the 
usual Trigonocarpum. Its appearance very much resembles the fruit of the 
Zaraia, figured in vol. i. of ManteU's " Medals of Creation." The smaller fruit

is about the size of a large pea ; it is much like the larger, but its lobes are 
not so rounded ; it appears to be the young of the other. If any of your 
readers have met with such an one, and will let me know, or if you will offer 
any remarks, it wiU oblige youi's, John Taylor, Levenshulme. 
Geology of Malta. — Sir, — Will you furnish me with some information on 
the subject of the deposits in the islaud of Gozo, off Malta ? 
The islands of Malta and Gozo consist of Tertiary rocks. These were 
described in 1843 by Captain Spratt, who with Lord Ducie has since prepared 
a geological map of these islands. In tlie Proceedings of the Geological 
Society, vol. iv., p. 225, &c., is an account of the beds found in the islands, 
namely, 1st and uppermost, coral- limestone ; 2, yellow sandstone and blue 
clay ; 3, freestone ; and 4, semi-crystalline limestone. These strata lie for the 
most part horizontally, though faulted and crumpled in some places. In the 
Benjennna lIRls the four groups of beds have a thickness of about six hundi-ed 
feet. Professor E. Porbes' report upon the fossils accompanied Captain 
Spratt's memoir. Since tlien Dr. Wright has figm-ed and described the fossil
