Abstract
1. Glycoproteins were isolated from the plasma of sheep, goat, cow, buffalo and monkey. They were homogeneous by electrophoresis; on ultracentrifugation, a faster-sedimenting fraction, to an extent of 5-8% only, was observed in each case. 2. Similar physical properties were exhibited by these glycoproteins and they each have a molecular weight of about 105000. 3. In chemical composition, differences have been observed and the glycoproteins can be classified into three groups: (a) sheep and goat glycoproteins; (b) cow and buffalo glycoproteins; (c) monkey glycoprotein. Glucose, galactosamine and N-terminal amino acid were absent from these proteins. 4. These glycoproteins were trypsin inhibitors and prolonged the clotting time of plasma.

Abstract
Two monkeys were trained on an escape-avoidance procedure in which a lever press delayed exposure to wind by 20 sec. For 5 hr, subjects alternately worked 15 min and rested 15 min, and performed this schedule when the wind was 5, 10, and 20 mph and the temperatures were 50, 60, and 70 degrees F. Analysis of variance showed that the percent of wind avoided was related to both the velocity of the wind and the temperature during the exposure. When the wind was 10 and 20 mph it was avoided almost continuously regardless of the temperature.

Abstract
Formal, Samuel B., (Walter Reed Army Institute of Research, Washington, D.C.), E. H. LaBrec, T. H. Kent, and S. Falkow. Abortive intestinal infection with an Escherichia coli-Shigella flexneri hybrid strain. J. Bacteriol. 89:1374-1382. 1965.-The mechanism of the apparent loss of virulence of an Escherichia coli-Shigella flexneri hybrid strain was studied. The parent Shigella strain caused a fatal enteric infection when fed to starved guinea pigs, and signs of dysentery followed its oral administration to monkeys. The hybrid strain failed to produce any apparent symptoms when fed to either of these species. The parent strain was shown to invade the intestinal mucosa of starved guinea pigs. This caused a severe inflammatory reaction in the lamina propria, which progressed to ulceration of the intestinal epithelium and resulted in death of the animal. The hybrid strain also invaded the intestinal mucosa and produced an inflammatory reaction. In this case, the inflammatory reaction subsided, the intestine returned to normal within 4 days after challenge, and the animal survived. Both fluorescent-antibody techniques and in vivo growth studies have shown that the hybrid strain can not maintain itself in the intestinal mucosa. Preliminary studies have indicated that a similar situation also exists in the monkey. It is concluded that the virulence of dysentery bacilli rests not only in the capacity to reach the lamina propria, but also in the ability to multiply in this region.

Abstract
Both response-contingent withdrawal of a visual reinforcement and response-contingent presentation of an aversive stimulus (loud noise) were found to be effective in suppressing toe-sucking in a young rhesus monkey.

Abstract
The nucleic acids produced intracellularly during the replication cycles of both DNA and RNA viruses can now be identified rapidly using a sensitized procedure based on staining with the fluorochrome acridine orange. Cellular DNA, viral DNA (both single and double stranded forms), cellular RNA, and RNA arising as a result of viral stimulus can be differentiated. The intracellular development of virus specific DNA, RNA, and protein has been studied in monkey kidney cells infected with adenoviruses types 3 and 7. It has been possible to detect a labile RNA in the nucleus from 16 to 20 hours after inoculation. When the cultures are treated with puromycin at this time, this RNA can be accumulated under certain conditions in the nucleus and demonstrated cytochemically. At the same time the production of specific viral protein as determined by staining with fluorescein-labeled antibodies is markedly inhibited. However, intranuclear double stranded DNA continues to be formed for a time. When puromycin is added to the system early in the eclipse period virus-specific DNA and labile RNA cannot be detected.

Abstract
1. A model of anthrax infection in rhesus monkeys closely simulating human inhalation anthrax has been employed to study the course of the illness and methods of recognition and therapy.2. Roentgenographic evidence of mediastinitis was detected early in the illness and served as a suitable indication for starting treatment.3. Therapy with either penicillin or tetracycline appeared efficacious when started at the time chest roentgenograms first evidenced disease.4. Isolation of penicillin-resistant B. anthracis from an animal dying during treatment with penicillin is reported.

Abstract
Rhesus monkeys in a colony were stimulated by means of intracerebral electrodes controlled by radio, for 5 seconds every minute, day and night, for periods up to 14 days. Stimulations of the red nucleus evoked a reliable sequence of behavior including bipedal locomotion, climbing, vocalization, and social interactions. During periods of spontaneous sleep, stimulations produced only a small head movement, but the whole behavioral sequence reappeared as soon as the animal awoke. In monkeys injected with chlorpromazine, the evoked behavior was inhibited in the same way as during spontaneous sleep, while the administration of atropine, Regitine, and Indurol which blocked both sympathetic and parasympathetic systems, produced only minor modifications of the sequential response.

Abstract
Attack behavior was elicited from squirrel monkeys by externally applied electric shock. The shock elicited attack toward other monkeys, rats, and mice, as well as toward inanimate objects, such as a stuffed doll, and even a round ball. A method of quantifying the attack behavior was devised on the basis of the attack against inanimate objects. This method revealed that the duration and probability of attack was a direct function of the shock intensity.

Abstract
Monkeys with surgically produced lesions of the orbital frontal cortex, monkeys with lesions of the lateral frontal cortex, and normal controls were tested for the effects of repeated presentation of novel stimuli on lever-pressing for food rewards. The results support the conclusion that the habituation of responses to novel stimuli was more impaired in monkeys with orbital frontal lesions than in monkeys with lateral frontal lesions.
