INSTRUCTORS and PURCHASING AGENTS who are on the lookout for newer and 

 belter sources for preserved material and shdes will be glad to learn that we are belter than ever 

 equipped to supply high quality material for the following sciences. 



BOTANY A set of microscopical slides of general 



morphology, which has been declared to 

 be of better quality and selection than 

 similar sets put out by any other com- 

 mercial firm in the United States. 

 A very complete line of preserved mate- 

 rial, excellent microscopical slides and 

 living material of many forms. 

 Microscopical slides of Trypanosoma 

 gambiense, Plasmodium vivax, Trepo- 

 nema pallida in tissue, Entamoeba his- 

 tolytica in sections of the human colon, 

 Necator Americanus and other economi- 

 cally important parasites. Also pre- 

 served material. 



Serial sections of 10 millimeter pig em- 

 bryos, in which a very high standard of 

 technique has been attained. Owing to 

 the method evolved, we are able to quote 

 very attractive prices on these. Serial 

 sections and whole mounts of Chick em- 

 bryos. Preserved pig embryos and chick 

 stages. Also slides and preserved mate- 

 rial illustrating the development of the 

 Starfish, Sea Urchin, Lobster Barnacle 

 and certain other invertebrates. 

 Excellent preparations of many represen- 

 tative forms. Cartilagenous skeletons 

 are mounted on glass background in 

 liquid. Ligamentous skeletons of bony 

 forms are prepared in such a manner that 

 all paits are properly shown in their 

 manural relations, with the use of visible 

 artificial supports. 



Should either preserved material or 



slides prove unsatisfactory, advise us and 



upon return of same we will refund both .
