SCIENTIFIC PROGRAM 



SIX CASES OF GLIOMA RETINA 



By Dr. Herminio E. Velarde 



Case histories, illustrated with photographs and skiagrams, of 

 six cases of glioma retinae were presented. All six cases were 

 females, the ages being from If to 4 years; the condition in 

 one case was observed shortly after birth. Cases reported in 

 the literature have occurred in children from 10 weeks to 13 

 years of age. Other members of the families were not affected. 

 In two out of the six cases the condition was bilateral ; the usual 

 figure is 25 per cent of bilateral cases. Metastatic involvement 

 of the liver was observed in two cases, of the scalp in two cases, 

 and also of the cervical glands, ribs, shoulders, thighs, pleura, 

 and dura mater. The prognosis of the disease is serious and 

 almost certainly fatal, as exemplified by the present series, if 

 early enucleation is not done. 



POISONOUS SNAKES OF THE PHILIPPINES 

 By Mr. E. H. Taylor 



Of the 25 deadly poisonous snakes known in the Islands, 18 

 species were shown in the demonstration. Of the Crotalinse, 

 or pit vipers, the following were examined : Trimeresurus gram- 

 ineus, from Luzon; T. flavomaculatus, from Luzon; T. schultzei, 

 from Palawan; T. wagleri (and two varieties), from Mindoro 

 and Palawan ; T. haliens, a rare species from Polillo. 



A new yellow viper (recently discovered on Batan Island, 

 Batanes Islands), as yet undescribed, was shown. 



The poison apparatus of this group was discussed, and the 

 large fangs, which attain a greater size in this group than in 

 any other, were observed and discussed.
