Dr. PuLTENE Y on the Jfcaruies difcwvered in the Tekcanus, l^c. 25 



appear to differ. In the recent ftate they were of a brownifti-yellow 

 caft, having loft much of the colour fnice they were put into the 

 brandy and water. This gentleman, and the party with him, killed 

 at the time upwards of twenty of thefe birds, in every one of which 

 worms of this kind were found ; and, what appears worthy of atten- 

 tion, is, that they were difcovered, together with fmall pebbles, and 

 fragments of wood, in the crops oi young Shags, that had never been 

 out of the neft. 



A few of thefe animals will be prefented to the Society with this 

 paper, and I think it will appear that they are all of the kind called 

 AfcarideSy the fpecies of which, or at leaft the different fpecies of 

 animals in which the fame is found, have been difcovered, of late 

 years, to be greatly more numerous than was formerly known ; ob- 

 fervations relating: to M'orms in the inteflines of animals havina: been 

 almoft wholly confined to thofe found in the human fpecies. 



Linnaeus defcribes only two Jfcarides, for the charafters of whicfi 

 I need only refer to the Syjlema Nature. It is to the difcoveries of 

 later authors that we owe the knowledge of a much greater number, 

 and find them now inhabiting a great variety of fubjefts throughout 

 the different clafles of the animal kingdom. It is well knov/n that 

 Redi was the firft writer who augmented the knowledge left us by 

 the Antients, or who extended enquiries on the fubjedl oi Aniiralcuht 

 which infeft the bodies of living animals. He mentions the J^fca- 

 rjdes of the Eagle, the Raven, the Swan, the Crane, and of fevcral 

 others*. x\fter his time, fcattered obfervations only were recorded, 

 and many years intervened before any confiderable advances were 

 made in this branch of fcicnce, howfoever clofely connccled with 

 the well-being of mankind.
