SYNOPSIS OF STUDIES IN METAZOAN PARA- 



SITOLOGY IN .Mc.MANES LABORATORY 



OF PATHOLOGY, IM\ KKSITY 



OF PENNSYLVANIA. 



BY ALLEN J. SMITH, M.D., 

 I'rofessorof I'lit/mlnt/i/, University of Pennsylvania. 



THE publication of statistical lists such as follows is more 

 rmmnon in the journals of special scientific societies than in 

 the usual medical journals; but in the present instance the 

 writer hopes to justify himself by the fact that the UNIV. OF 

 I'EN.NA. MKD. Hn.i.ETiN is the official organ of the institution 

 in which these studies were made, and, too, by his desire to 

 keep in proximity this list of records with the special de- 

 scriptions of new parasites included and published in this 

 same journal. For the most part, the parasites submitted 

 for examination have, because of the correspondence of 

 findings with already published descriptions, been merely 

 named without other comment than the numbers of record 

 and a statement of their habitat and host, and an acknowl- 

 edgment of the person who collected the specimens. For 

 further reference, should this in any case be desired, the 

 reader may consult the books of the laboratory, in which the 

 details of the various examinations are preserved. The 

 value of such synoptical lists lies mainly in the aid they 

 give parasitologists in determining the range of occurrence 

 of parasites, the variety of hosts in which they have been met, 

 and their habitat in the host; and it is for this reason that 

 they should be of public record.
