A TREATISE 



ON 



Apis (The Bee), Tela Araneae 



(Cobweb), Spongia and 



Cantharis. 



By John Uri Lloyd, Phar. M. 



Drug Treatise No. XXI has been delayed many months, owing to 

 the research necessary to the systematic presentation of the subjects em- 

 braced therein. This will be apparent to every studious recipient, and 

 yet the bibliographical references presented but poorly indicate the 

 researches necessarily made among volumes of past literature, unnamed 

 in these pages. 



Historical data, as well as therapeutical references, are cited in each 

 instance, and the author asks that full credit be given to one and all. 



The Librarian of the Lloyd Library, Captain William Holden, 

 has been of incalculable assistance, and to him our especial thanks are 

 due. 



To the care of the author's secretary, Miss Margaret Stewart, 

 A. M., as well as to her translations, pages 21 and 39, is due the com- 

 pleteness of each subject. 



The author hopes that this study of a few remedies now little known, 

 and their past records, which are even less familiar, will be of some in- 

 terest and service to both physician and pharmacist recipients.
