SimiUtud'ine ornaf/.s;" and in an appendix to his " de Aquatilibiis

Sir Robert was contributor of several papers to the Philoso- 

 phical Transactions. In volume lyth there is an account of some 

 Scotch shells, addressed to Dr. Lister ; and in the 25th volume a 

 description of Avhat the author calls Pediculus ceti {Lepas diadema, 

 Linn.) forms part of a letter to Sir Hans Sloane. 



The refutation of the absurd story of the Barnacle Goosewas 



undertaken by many writers about this time, and among others

ERICUS A MOINICHEN, 



whose name is prefixed to a dissertation entitled " Conchce anati- 

 fera rindicato'." 



In the number of writers who have treated of the physiology of 

 the Testacea, the celebrated 



LEEUWENHOEK 



deserves to hold a distinguished place. His first production on this 

 subject Avas addressed to the Royal Society, and relates chiefly 

 to the generation of these animals : the ova and the intestinal 

 structure of certain Mytili are also particularly described. His 

 95th epistle treats of the ovaria of ConcIicB in general, and is illus- 

 trated by some good figures. Another describes the ova of ditle- 

 rent shells. Lastly, in an epistle dated l?!?, he gives an account 

 of the tendinous substances belonging to some bivalves; but it is 

 very concise, and introduced only in a cursory manner, when he 

 is treating of the structure of tendons in general.
