Needle aspiration of lymph nodes was used at the beginning of the 20th century to identify parasites in sleeping sickness, secondary syphilis, filariasis, and bubonic plague. In 1921, Guthrie at the Johns Hopkins Hospital described systematic diagnosis of lymph node aspirates using air dried films and Romanowsky staining. This began the modern development of this technique and I intend to summa...

In this paper, we present three improvements to a three-point third order variant of Newton’s method derived from the Simpson rule. The first one is a fifth order method using the same number of functional evaluations as the third order method, the second one is a four-point 10th order method and the last one is a five-point 20th order method. In terms of computational point of view, our method...
