OBITUARY. 



Lawrence M. Lambe. 



By the death of Lawrence Lambe, which oc- 

 curred on March 12th, 1919, the Canadian Geo- 

 logical Survey lost one of its best known scientists. 

 Mr. Lambe was the Vertebrate Palaeontologist of 

 the Geological Survey of Canada. 



Lawrence M. Lambe was born in Montreal, on 

 August 27th, 1863. His father, Wm. B. Lambe, 

 was an Englishman who came to Canada when a 

 young man. His mother was of Schotch descent, 

 the daughter of Hon. Wm. Morris, of Montreal. 



Lambe's college training was taken with a view to 

 entering the profession of civil engineer. He se- 

 cured shortly after his graduation from college a 

 position with the engineers of the mountain division 

 of the C. P. R. It is most probable that he would 

 have remained a civil engineer but for the fact that 

 an attack of typhoid fever compelled his return 

 home. Although offered, after his recovery, an- 

 other position on the engineering staff of the C.P.R. 

 he preferred an appointment to the Canadian Geo- 

 logical Survey. 



Much of Mr. Lambe's training in zoology and 

 palaeontology was acquired chiefly through his 

 association with that keen naturalist and palaeon- 

 tologist. Dr. J. F. Whiteaves. This association be- 

 gan when Lambe, at the age of twenty-two, re- 

 ceived his first appointment to the Canadian Geo- 

 logical Survey as artist and assistant to Dr. 

 Whiteaves. At a considerably later period he 

 studied with Dr. H. F. Osborne at Columbia Uni- 

 versity. Concerning this period of Mr. Lambe's 

 career. Dr. Osborne writes as follows: — 



"When I was appointed in April, 1900, on the 

 Geological Survey of Canada, as palaeontologist, 



to succeed Professor Edward D. Cope, I chose 

 Mr. Lawrence M. Lambe as my chief associate 

 and I immediately engaged with him in the study 

 of the fauna of the Belly River, which was pub- 

 lished in 1902 (see Osborn Bibliography 1902. 217). 

 He afterward came to Columbia University and 

 took my full course in vertebrate palaeontology." 



Analysis of Lambe's publications shows three 

 distinct s'.ages in his development as a scientific work- 

 er. His first three papers dealt with living marine 

 sponges. His contributions to zoology all relate to 

 sponges and extend over a period of thirteen years, 

 beginning in 1892. His first contribution to inver- 

 tebrate palaeontology appeared in 1896, fcur years 

 after he had begun publishing on sponges. Two 

 years later his first paper on vertebrate fossils was 

 published. His papers published since 1900 relate 

 with few exceptions to vetebrate palaeontolcgy, 

 the subject with which his name in recent years has 

 been chiefly associated. Lambe's most important 

 work on invertebrate fossils relates to the corals. 

 For a short period after the death of Dr. J. F. 

 Whiteaves, the determination of all of the palaeon- 

 tological collections of the Canadian Geological 

 Survey fell to Mr. Lambe, — a task which few palae- 

 ontologists could have ventured to undertake. After 

 1910, Lambe was able to devote his energies l.-.- 

 clusively to vertebrate palaeontology. He had, too, 

 during the later part of his career the good for- 

 tune to have the assistance of the Slcrnbergs who 

 collected for him a wealth of dinosaurs and other 

 material from the Alberta Cretaceous. 



Lambe's interest centered in the office elaboration 

 and description rather than in the collection of fos-
