One group of 5 male & 5 female albino rats of the Sherman-Wistar Strain weighting between 200 and 300 gm were employed in this study. The rats were deprived of food but not water for 24 hours prior to dosing. Each animal was weighed and dosed by direct administration of the experimental material into the stomach by means of a syringe and dosing needle. The sample was dosed as a 50% w/v suspension in water. The following dosage level was administered: 1,000 mg/kg. Following administration the animals were allowed food and water ad libitum for the 14 day observation period during which time the rats were observed for signs of toxicity and mortalties. See Table 1. The subject material when studied in male and female albino rats has an acute oral LDc0 of less than 1,000 mg/kg. 4i<A Karl L.
