INSTRUCTORS and PURCHASING AGENTS whoare on the lookout for newer and 
better sources for preserved material and slides will be glad to learn that we are better than ever 
equipped to supply high quality material for the following sciences. 
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. Seria! 
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 parts 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 
purchase price and transportation costs.
