 Portions of apples were exhibited with dense hemispherical groups 

 of attached barnacles an inch and a half in diameter with the barna- 

 cles from 2 to 8 lines long, and several cranberries with bunches in 

 which the barnacles are from 2 to G lines long. 



Reputed Tape-worm in a Cucumber. — Prof. Leidy stated that 

 several years ago, his colleague in the University, Prof. Wm. Goodell,. 

 submitted to his examination a tape-worm, which he received from a 

 correspondent, with the label "From the middle of a cucumber pre- 

 served in brine. S. E. Robinson, West Union, Iowa, May 29, 1876." 

 The specimen appears to be complete and in its present condition, 

 preserved in alcohol, is about eight inches long. The head is large, 

 spheroid, provided with four, small, equi-distant hemispherical both- 

 ria, and surmounted by a prominent crown with a double circle of 

 strong hooks. The neck is a slight constriction whence the body 

 rapidly widens and again tapers behind. The anterior segments are- 

 transversely linear with a gradually increasing length and more 

 acute and prominent lateral ends; the middle segments are about 

 twice the breadth of the length and slightly companulate; and 

 the posterior segments are proportionately longer and narrower. In 

 the latter, the uterus is distended with eggs only at their anterior 

 portion. 



The hooks are partially lost on one side of the crown ; and it is 

 estimated that there were about 40 or more. 



The head is •875 mm. broad; the crown of hooks '625 mm.; the 

 neek '8 mm. ; at the middle of the body six segments together are 

 1 cm. long and o'5 mm. wide; the terminal segments are about 4 mm. 

 long and 2*5 mm. wide. The eggs measure from '032 to '036 mm. 



While it cannot be admitted that the worm belonged to the cucum- 

 ber, nor is it clear how it reached this position, it is a question as to 

 the species. It bears a near resemblance to the Taenia crassicollis of 

 the Cat, but is not more than half the size of this as it ordinarily 

 occurs. 



In comparison with a complete specimen of the latter, six inches 

 in length in the contracted condition as preserved in alcohol, we find 

 the following measurements.

Diamonds in Meteorites. — Professor Carvill Lewis exhibited a 

 small fragment of a meteorite which had fallen in the district of 

 Krasnoslobodsk, Government of Penza, Siberia, on September 4, 1886,
