lutely erect position witliout having his hands

The outside cages at the new monkey house 

 were erected and put into use during the sum- 

 mer, thus finally completing what is without 

 doubt the most pleasing and well adapted 

 building on the grounds. Plans have been pre- 

 pared for a house for small mammals, to be 

 erected upon the site of the old monkey house, 

 all of which will be torn down, with the excep- 

 tion of the stone portion of the outer walls. 



A large piece of ground lying between the 

 Carnivora House and the eastern main walk 

 has been enclosed by an iron fence, to contain 

 the elk and a similar pen, has been made for 

 ■common camels on the opposite side of the walk 

 to the west. 



A similar construction is projected on the 

 western main walk, opposite the Carnivora 

 House, for Bactrian camels. The removal of 

 the elk and camels from the series of pens on 

 the western side of the gardens has made it 

 possible to give the American buffalo the whole 

 space, measuring some 420 feet in length, with 

 a depth of from 110 to 180 feet. While the 

 conditions afforded by such an enclosure fall far 

 short of those which are to be desired, they are 

 probably as good as can be supplied in a zoolog- 

 ical garden of average size, and, on the whole, 

 the condition of the herd of buffalo owned by 

 the Society is most gratifying. 



SOLOMON STRICKEK. 



We take from an obituary notice in The 

 British Medical Journal the following details 

 regarding the life and work of the late Pro- 

 cessor Strieker. 



Born in 1834 in Waag-Neustadt, in Hun- 

 gary, he studied in Pressburg and Ofen Pest ; 

 afterwards he went to Vienna, where he ' in- 

 scribed ' as a student of law, but soon turned 

 to medicine. In his second year of medical 

 study he began to work under Briicke (1855-58). 

 In 1858 he graduated as BI.D.; in 1859 he be- 

 came Assistant in the General Hospital, in 1862 

 a Privat-docent for ' Entwicklungsgeschichte,' 

 -and in 1863 he again became Assistant to 

 Briicke. In 1865 he published his discovery of 

 the diapedesis of the red blood corpuscles and 

 i;he contractility of the capillary wall. At the 



end of the war of 1866 Cohnheim was in Vienna, 

 where began a friendship between these two. 

 In 1866 Oppolzer selected Strieker to develop 

 the experimental method as applied to physi- 

 ology and pathology in his clinic. Through 

 the strong friendshiiJ which sprang up between 

 Strieker and Rokitausky, Strieker in 1868 was 

 nominated professor (estraordinarius) of ex- 

 perimental pathology, with a very modest and 

 limited laboratory. In 1869 appeared his 

 Studien a. d. Institute f. exp. Pathologie. In 

 1870 he visited England, and in 1871 his then 

 assistant, Dr. Klein, came to London. 



In 1871-73 appeared his Handhuch d. Lehre v. 

 d. Geivehen d. Menschen u. d. Thiere (translated 

 in 3 vols.. New Sydenham Society, Human and 

 Comparative Anatomy). Chiefly through the in- 

 fluence of Rokitausky, Strieker was nominated 

 pi'ofessor of general and experimental pathol- 

 ogy. The chief results of the work done by his 

 pupils in his laboratory were edited by Strieker, 

 and published in the well-known Med. Jahr- 

 bucher (1871-80). In 1877-83 appeared his Vor- 

 lesungen iiber allgem. u. exp). Pathologie. 



Strieker recognized the importance of experi- 

 mentation for the advancement of medicine, 

 and, although in his course in 1883 he confined 

 himself to histological demonstrations, he soon 

 developed an auditorium replete with apparatus 

 for all kinds of experimentation, and so ar- 

 ranged that everyone in the audience could 

 profit thereby. He laid great stress on this 

 subject in his lectures, which were often at- 

 tended by over 400 students. 



Strieker regarded the study of tissues not as 

 an end, but as the means of ascertaining the 

 course of events in living tissues ; he studied 

 not so much tissue morphology as tissue physi- 

 ology, and to this end he invented his 'hot 

 stage.' Strieker, through his pupils, also con- 

 tributed much to our knowledge of vasomotor 

 nerves, efferent fibres in the posterior roots of 

 spinal nerves, the action of diuretics, the anaes- 

 thetic action of cocaine, etc. 



Besides strictly medical papers, Strieker pub- 

 lished several philosophical works : ' Studien 

 iiber Bewusstsein ' (1879), ' Sprachvorstellung' 

 (1880), ' Bewegungsvorstellung ' (1882), 'Asso- 

 ciation d. Vorstellungen ' (1883), and ' Physio- 

 logie d. Rechts' (1884).
