Chemically Treated Bands

In Illinois over a five year period the cold dipped, corrugated paper band (Powdered beta naphthol―1 lb., 200-300 seconds viscosity oil―1½ pints, gasoline―1 pint) has been as effective in stopping codling moth ( Carpocapsa pomonella ) emergence as the hot dipped band. The cold band has advantages as to uniformity of deposit, fire hazard and ease of preparation. New cold dipped formulae of high efficiency are given.

Anthelmintics and their Uses in Medical and Veterinary Practice

The text presents a logical arrangement. Section I contains a general treatment of the anthelmintics, an excellent summary of the helminths of man and domestic animals, and a discussion of the correlation between chemical composition of the drugs and their anthelmintic action. The subtitle of Section II is “Anthelmintics Acting on Parasites in the Gut.” The particular drugs used in the treatment of the cestodes and the nematodes are here considered: Male Fern, Pelletierine, Carbon Tetrachloride, Chenopodium, Santonin, Thymol, Beta Naphthol, and numerous others, some of them even of slight or doubtful value. Certain proprietary preparations are also discussed. Section III deals with “Anthelmintics used against somatic parasitic infections,” the various antimony preparations and emetine. The more important drugs receive extensive treatment. For example, Carbon Tetrachloride is presented in outline as follows: Historical and General, Chemistry, Impurities and Tests for them, Pharmacological Action, Toxicology, Dosage and Methods of Administration, Effectiveness, Uses in Animals, and the Combination of Carbon Tetrachloride and Chenopodium.

The detection of small amounts of chloral in the presence of chloroform and formalin embalming fluid

During the past five years the organs of many cases in which death was due to toxic substances, were submitted to complete chemical examination in this laboratory. Practically all of these were examples of sudden death occurring in the five boroughs of Greater New York for which the chief medical examiner or the medical assistant to the district attorney or both could find no anatomical cause. There were also a number of cases which were brought to my attention from other states. In this number, most of the commoner poisons, including chloroform, were represented. I have yet to encounter a case of straightforward chloral poisoning. Nevertheless, I became greatly interested in the question as to whether some of the so-called chloroform poisonings might not have actually been examples of chloral poisoning, and therefore, I made a study of various reactions to determine this point. The several tests, namely, the isonitrile, the resorcin, the orcin the alpha and beta naphthol, the Ragsky, the cyanide, the formic acid and the Vitalli Tornani, were stiudied, first, with relation to sensitiveness, second, as to the possibility of differentiating chloral from chloroform and, third, as to the interference of formalin with these reactions. The isonitrile and resorcin tests were found to be the most sensitive. By the former, chloral can be detected down to a dilution of .05 mgs. to the c.c. The resorcin test indicates chloral only to .25 mg. in one c.c., if the test is judged by the color alone; at this point the test is discarded if no red color appears. Chloral in amounts under .25 mg. per c.c. may still be present and detected by the appearance of a slight greenish fluorescence on diluting the reaction product with 10 c.c. of water.
