ORIGINAL OBSERVATIONS, WITH PHOTO 

 GRAPHIC ILLUSTRATIONS, ON REPTILES 

 AND INSECTS OF TEXAS.

READ BEFORE THE SOCIETY, OCTOBER 11, 1904. 



Mr. President, and Gentlemen of the Scientific Society of San 

 j. Intonio : 



Some time ago I noticed in the local press that it was the in- 

 tention of your society to prepare a collection of objects inter- 

 esting- to science and natural history, and, as I had a number of 

 original photo plates illustrating such subjects, accumulated 

 during many years, it occurred to me that these plates could 

 be utilized to advantage by your honorable society. Accord- 

 ingly, through the kindness of Dr. M. J. Bliem, the plates 

 were printed and the copies were mounted in the form of three 

 separate charts — two representing photos of divers animals 

 and insects indigenous to our Texas climate, the third chart 

 representing microscopic objects, prepared by the photo-micro- 

 graphic process, which, perhaps, will be discussed, specifically, 

 on some future occasion. 



Our Texas insects, particularly those of the venomous type, 

 furnish a great field for scientific research, and in a short re- 

 view such as the one now to follow, of course only a few of 

 the more important objects seen on some of the charts can be 

 considered- 



Among the most harmless of insects, our Texas butterflies 

 abound in manifold species and luxuriant colors, and those on 

 the chart represent only a few of the more interesting species. 

 reproduced in natural size and colors. They were all prepared, 

 shortly after capture, on a 4x5" plate with extra lens appliances
