This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1899 Excerpt: ...by others. The next step was to put to practical use the knowledge gained, and experiments have since been conducted on a large scale to find a means of ridding southern cattle of their ticks. Norgaard"' in 1895 and 1896 published a report stating that the ticks could be removed effectually by bathing cattle in vats containing certain solutions. It was difficult to find a bath which injured the tick and not the cattle. 25 per cent glycerine was effective but naturally too expensive. The best results were obtained with chloronaphtholeum, 2 per cent (50 pounds), with 40 pounds of soap in a vat 5 feet deep containing 2500 gallons of water. 24 hours after dipping all the smaller ticks were dead, also many gorged ones. After 4 to 5 days all the ticks had turned black and died. Ticks have also been found associated with Texas fever by Pound" and by HuntTM (1895) in Australia. Pound recommends burning off the grass on infected pastures as a prophylactic measure. Hunt claimed to have found the parasite in young ticks, but this seems scarcely credible, as various trustworthy investigators in the United States have been unable to find them. Hunt, as well as others, failed to produce Texas fever by injecting crushed young ticks hypodermically, it being impossible at present to offer an explanation of the fact. Hill"1 (1895) found ticks on cattle suffering from Texas fever in California. Since Smith's publication the parasite has also been found affecting cattle in Roumania, South Africa, the Campagna of Rome and in the low country along the Danube. Quite recently Koch"' " (1898, I and II, see under Malaria literature) reported that he observed the disease amongst cattle in German East Africa. The disease extends there along the whole coast, pr...
