454 SCIENCE PROGRESS. 



The second feature which seems to us even more com- 

 mendable is the appearance of a series of articles dealing 

 with the history of renowned Helminthologists. The editor 

 himself contributed to the April number a sketch of the life 

 and work of Prof. R. Leuckart, illustrated by a character- 

 istic portrait and a facsimile letter, and in the current issue 

 is an admirable account of Francesco Redi. This remark- 

 able physician, poet, courtier, lexicographer and zoologist, 1 

 who was born at Arezzo in 1626 and was buried in the 

 church of San-Francesco in the same Tuscan city in 1697, 

 was one of the earliest and greatest investigators into the 

 anatomy and habits of Entozoa. He investigated with that 

 object not only the bodies of numerous Vertebrates but also 

 those of Cephalopods and Crustacea, and was the first to 

 describe the Liver-fluke, a fact recorded by the name Redia, 

 given to the larval Trematode by Filippi who first discovered 

 it. Altogether Dr. Guiart records some seventy-five species 

 of Entozoa studied by Redi. 



The articles of a more strictly scientific nature are too 

 numerous to mention ; besides the more lengthy memoirs 

 their are numerous short notices and reviews, so that the 

 whole forms a compendious survey of the advance made 

 day by day in the study of Parasitology.

1 If we may trust the poet, Redi was among the small number of tee- 

 totalers who have sung the praises of wine. 



" Even Redi when he chaunted 



Bacchus in the Tuscan valleys, 

 Never drank the wine he vaunted 



In his dithyrambic sallies." 



— Drinking Song. H. W. Longfellow.
